Bed rest in the acute stage with close observation is the mainstay of treatment in mild and asymptomatic cases buy antabuse online pills medications valium. Digitalis is avoided during the acute stage of the inflammation due to possible cardiac side effects such as ventricular arrhythmias order antabuse 250mg with amex medications 3601, although it can be used in the chronic stage of the disease or in those who progress to dilated cardiomyopathy discount antabuse 500 mg medications ok for pregnancy. Other therapies order antabuse toronto treatment for depression, such as the use of immunosuppressive therapy and immuno- modulating agents like intravenous immunoglobulin is still controversial. So far studies showed no benefit of steroids or other immunosuppressants in the long-term outcome of the disease. Patients who present with fulminant myocarditis or intractable arrhythmias may need mechanical support like extracorporeal membrane oxygenation, ventricular assist devices, or even heart transplantation. Prognosis The long-term outcome of patients with acute myocarditis varies by the initial pre- sentation. Torchen Patients who present with acute fulminant myocarditis have the best recovery outcome if they survive the initial acute stage, with full recovery of ventricular function in >90% of patients in one series. Overall, about 1/2 to 2/3 of pediatric patients with myocarditis show complete recovery, 10% have incomplete recovery and up to 25% either die or require heart transplantation. Case Scenarios Case 1 History: A previously healthy 3-year-old boy is brought to the emergency room because he has been having abdominal pain and vomiting for the last 2 days. Physical examination: The patient’s physical examination shows that he has mild dehydration. Differential diagnosis: Based on the information obtained so far, it appears that this child has some degree of heart failure, based on the findings of tachycardia, tachyp- nea, hepatomegaly, cardiomegaly, and increased vascular markings on chest X-ray. Other causes such as endocarditis, myocarditis, or pericarditis must be considered. Final diagnosis: An echocardiogram is performed which shows dilatation of the left ventricle with decreased systolic function and moderate mitral regurgitation. It is usually preceded by a viral prodrome of either upper respiratory tract infection or gastro- enteritis. He recovers from the acute phase of the disease and is then discharged home on an oral ace inhibitor, aspirin, and a diuretic. Case 2 History: An 8-month-old infant is brought to the emergency room by ambulance after what is thought to be a brief seizure episode. This infant was previously healthy and was playing at home when she suddenly became limp and unresponsive for a few seconds prior to regaining consciousness. She had a preceding upper respiratory tract infection and low-grade fever 5 days prior to this episode. Physical examination: On physical exam, the patient is fully awake and alert with mild tachypnea. Investigative studies: Laboratory workup shows mildly elevated white cell count, with lymphocytic predominance. Differential diagnosis: The differential diagnosis remains quite broad at this time. However, the anion gap metabolic acidosis is more concerning; causes including hypoperfusion leading to lactic acidosis, diabetic ketoacidosis, and toxic ingestion must be considered. During this observation period, she has another episode dur- ing which she becomes pale, dusky, and limp. An echocardiogram performed upon arrival to the tertiary care center is significant for dilatation of the left ventricle with decreased systolic function. Assessment: This is a less common presentation of acute myocarditis presenting with loss of consciousness secondary to ventricular arrhythmias. This patient needs man- agement in a pediatric cardiac intensive care with access to cardiovascular mechan- ical support that may be needed in case of arrhythmia unresponsive to medical therapy. She is maintained on mechanical ventilation with inotropic support and diuretics during the acute phase of her illness. Naheed and Laura Torchen Key Facts • Dilated cardiomyopathy is the most common form of cardiomyopathy. Definition Cardiomyopathy is a disease of the myocardium resulting in thickening of the myocardial fibers or fibrosis. Hypertrophic cardiomyopathy is characterized by thickening of the muscular walls of the ventricles, typically involving the ven- tricular septum. Dilated cardiomyopathy may also cause hypertrophy of the ventricu- lar walls, however due to severe dilation of the ventricular chambers, they appear thin and stretched. Torchen Incidence Cardiomyopathy is a chronic and variably progressive disease of the heart muscle that can present in various forms and in severe cases can lead to heart failure and sudden death. However, it has to be noted that many asymptomatic and undiagnosed cases are unaccounted for in this survey. Infants less than a year old are ten times more likely to develop cardiomyopathy compared to children aged 2–18 years. Pathology Hypertrophic cardiomyopathy is characterized by abnormal growth and arrange- ment of muscle fibers, termed muscle disarray. The process starts in the ventricles and in severe cases can involve the wall of the atria. It can be acquired, secondary to a viral infection or chemotherapy, or inherited as an autosomal dominant, auto- somal recessive, or X-linked disease such as the Barth Syndrome. Cardiomyopathy could also be secondary to a more generalized metabolic, mitochondrial, or multi- system disorder. In hypertrophic cardiomyopathy most commonly the left ventricle is the more affected chamber with the septum showing the most growth. The thickening can sometimes be symmetric or concentric involving the entire left ventricular wall or localized to the apex in rare cases. After starting as a patchy lesion, the process can gradually spread to involve the entire right ventricle and then to the left ventricle. Hypertrophic cardiomyopathy causes abnormal relaxation of the heart during diastole and secondary obstruction to venous return. In the terminal stages of this disease, the heart resembles those seen in a dilated cardiomyopathy. In restrictive cardiomyopathy there is normal systolic function but abnormal relaxation. Clinical Manifestations Cardiomyopathy is not gender, race, geography or age specific. About 50–60% of children with hypertrophic cardiomyopathy and 20–30% with dilated cardiomyo- pathy have a family history. Symptoms of hypertrophic cardiomyopathy could first manifest with the spurt of growth during puberty. The general symptoms, not specific to any single type of cardiomyopathy, include tac- hypnea, poor feeding, and failure to thrive in infancy and poor exercise tolerance in older children. Other presenting features may include a murmur, arrhythmias, chest pain and syncope. In restrictive cardiomyopathy, common presenting symptoms include resting tachypnea, easy fatigability, syncope, chest pain, or dry cough. Cardiomyopathy may be associated with a metabolic disorder which may present with symptoms such as muscle weakness, decreased muscle tone, growth retardation, developmental delays, failure to thrive, or constant vomiting and lethargy. There also may be an association with a malformation syndrome with dysmorphic features specific to the syndrome, such as short stature and webbed neck seen in Noonan’s syndrome. Diagnostic Testing Any suspicion of cardiomyopathy should prompt a consult to the pediatric cardiologist. Echocardiogram is the most widely used and most informative noninvasive test for diagnosing cardiomyopathy. With echocardio- gram, the practitioner cannot only specify the type of cardiomyopathy but also determine the degree of dysfunction of the heart muscle. Measurements of the pressures in the ventricles and the great vessels like the pulmonary artery may also be performed. In addition a chest X-ray, electrocardiogram and a 24–72 h Holter monitor are necessary for evaluation. In some cases there may be need for more invasive tests like radionuclide ventriculogram or cardiac catheterization. This helps in evaluating for possible infections of the heart and certain metabolic diseases. Certain biochemical, genetic and enzyme deficiency tests are needed before starting the most appropriate medical therapy. It is especially important to get a metabolic screening in children with cardiomyopathy under 4 years of age. This may require additional blood, urine and tissue testing in consultation with special- ists such as geneticists or neurologists. Improving the contractility by using dopamine and dobutamine in critically ill patients and digoxin orally as maintenance therapy. Control of symptoms related to obstruction with calcium channel blockers or beta blockers like verapamil and propranolol. Prevention of arrhythmias and sudden death with antiarrhythmics like amio- darone or disopyramide. Patients with associated metabolic disorders may need careful dietary monitoring of fats, avoidance of fasting and possible daily carnitine orally. Dual chamber pacing has been shown to decrease outflow obstruction in hypertro- phic cardiomyopathy. An automatic internal cardioverter defibrillator is recom- mended in cases of severe life threatening arrhythmias, syncope, or history of resuscitation from a cardiac arrest. Myectomy is the surgical removal of part of the thickened septal muscle that blocks the blood flow in hypertrophic cardiomyopathy. Even though it may control symptoms of heart failure secondary to obstruction, studies have not shown that this procedure prevents sudden death from arrhythmias or stops progression of the disease. Heart transplantation is the last resort when patients reach the end stage of the disease. About 20% of symptomatic infants with cardiomyopathy require a cardiac transplant within the first year of life.

This should include help interpreting publicly available data, information on other clinical specialties offered by alternative units (particularly for patients with co-morbidities), accessibility of alternative units, patient facilities offered by alternative units, outcomes at units under consideration and consideration of the closest unit to the patient’s home. This feedback should be openly available together with outcome of relevant local and national audits. Governance The Network will have a Governance Framework in place which includes arrangements for:  Regular continuous clinical audit and quality improvement. Patient registers/database  All children transferring between services will be accompanied by high quality information, including a health records summary and a management or follow up plan. The protocols will be developed and agreed with local referring Paediatricians, Paediatric Cardiologists, Children’s Cardiac Specialist Nurses, Clinical Psychologists and Patient Groups. Annual reports Congenital Heart Networks will produce annual audit and governance reports covering paediatric cardiac services. The Specialist Children’s Surgical Centre will work with the Specialist Children’s Cardiology Centres and Local Children’s Cardiology Centres within the Network to:  Manage and develop referral and care pathways;  Manage and develop treatment and transfer pathways;  Develop network policies, protocols, and procedures;  Performance monitor through agreed governance arrangements;  Undertake audit, professional training and development;  Facilitate the development of as much care and treatment as possible close to the child’s home;  Manage the transition to adult services; and  Continually review the pathways to ensure they provide the best care and support for parents and their children. They will facilitate regular face-to-face and teleconference attendance by Specialist Children’s Cardiology and Local Children’s Cardiology Centres. To ensure equity of access, wherever possible, access to the service should be according to common routes, policies and criteria that do not disadvantage any relevant patient group. It should be noted that around 10% of patients have some form of learning disability. Acceptance criteria  Pregnancy with either suspected fetal heart disease or at high risk of fetal heart disease  All patients (including patients with congenital heart disease and inherited/ acquired conditions) before the sixteenth birthday at referral, with suspected or confirmed heart disease. In some cases it may be appropriate to offer choice to older teenagers (up to the eighteenth birthday). Exclusions The specification excludes:  Major airway surgery undertaken by Congenital Cardiac Surgical teams This service specification applies to any patient with a congenital heart condition requiring treatment, and whose condition enters them onto this pathway of care. Supra-Regional Services  Potential candidates for paediatric cardiac transplantation (including implantation of a mechanical support device as a bridge to transplantation) must be referred to a designated paediatric cardiac transplant centre. The designated transplant centre is responsible for managing and developing referral, care, treatment and transfer policies, protocols and procedures in respect of transplant patients. Out-of-hours arrangements must take into account the requirement 156 Classification: Official Paediatric Cardiac Services Specification for surgeons only to undertake procedures for which they have the appropriate competence. Congenital interventionists based at other hospitals may participate in this rota. Each consultant congenital interventionist must be primary operator in a minimum of 50 congenital procedures per year, averaged over a three-year period. Units will require more than one cardiologist with training in fetal cardiology to meet the requirements of the fetal cardiology standards. They will lead a dedicated team of nursing staff trained in the care of children who have received cardiac surgery. The precise shape of each Congenital Heart Network should be determined by local need and local circumstances, including geography and transport and agreed by Area Team Commissioners. Where a fetal cardiology service exists this must be supported by a Children’s cardiac nurse specialist with experience in fetal counselling. The precise shape of each Congenital Heart Network should be determined by local need and local circumstances, including geography and transport and agreed by Area Team Commissioners. Service description/care pathway All paediatric specialised services have a component of primary, secondary, tertiary and even quaternary elements. The efficient and effective delivery of services requires children to receive their care as close to home as possible dependent on the phase of their disease. Services should therefore be organised and delivered through “integrated pathways of care” (National Service Framework for children, young people and maternity services, Department of Health & Department for Education and Skills, 2004) Paediatric Imaging All services will be supported by a 3 tier imaging network (‘Delivering quality imaging services for children’ Department of Health 13732 March 2010). Within the network:  It will be clearly defined which imaging test or interventional procedure can be performed and reported at each site  Robust procedures will be in place for image transfer and review by a specialist 165 Classification: Official Paediatric Cardiac Services Specification radiologist, these will be supported by appropriate contractual and information governance arrangements. Specialist Paediatric Anaesthesia Wherever and whenever children undergo anaesthesia and surgery, their particular needs must be recognised and they should be managed in separate facilities, and looked after by staff with appropriate experience and training (1). However those working in specialist centres must have undergone additional (specialist) training (2) and should maintain the competencies so acquired (3). These competencies include the care of very young/premature babies, the care of babies and children undergoing complex surgery and/or those with major/complex co-morbidity (including those already requiring intensive care support). Specialist acute pain services for babies and children are organised within existing departments of paediatric anaesthesia and include the provision of agreed (hospital wide) guidance for acute pain, the safe administration of complex analgesia regimes including epidural analgesia, and the daily input of specialist anaesthetists and acute pain nurses with expertise in paediatrics. Accommodation, facilities and staffing must be appropriate to the needs of children and separate from those provided for adults. All staff who work with children and young people must be appropriately trained to provide care, treatment and support for children, including Children’s Workforce Development Council Induction standards (Outcome 14b Essential Standards of Quality and Safety, Care Quality Commission, London 2010). Each hospital who admits inpatients must have appropriate medical cover at all times taking account of guidance from relevant expert or professional bodies (National Minimum Standards for Providers of Independent Healthcare, Department of Health, London 2002). Staff must carry out sufficient levels of activity to maintain their competence in caring for children and young people, including in relation to specific anaesthetic and surgical procedures for children, taking account of guidance from relevant expert or professional bodies (Outcome 14g Essential Standards of Quality and Safety, Care Quality Commission, London 2010). Providers must have systems in place to gain and review consent from people who use services, and act on them (Outcome 2a Essential Standards of Quality and Safety, Care Quality Commission, London 2010). These must include specific arrangements for seeking valid consent from children while respecting their human rights and confidentiality and ensure that where the person using the service lacks capacity, best interest meetings are held with people who know and understand the person using the service. Staff should be able to show that they know how to take appropriate consent from children, young people and those with learning disabilities (Outcome 2b) (Seeking Consent: working with children Department of Health, London 2001). Children and young people must only receive a service from a provider who takes steps to prevent abuse and does not tolerate any abusive practice should it occur (Outcome 7 Essential Standards of Quality and Safety, Care Quality Commission, London 2010 defines the standards and evidence required from providers in this regard). Providers minimise the risk and likelihood of abuse occurring by:  Ensuring that staff and people who use services understand the aspects of the safeguarding processes that are relevant to them. Implementation is expected to contribute to improvements in health inequalities and public health outcomes. All providers delivering services to young people should be implementing the good practice guidance which delivers compliance with the quality criteria. Transition Poorly planned transition from young people’s to adult-oriented health services can be associated with increased risk of non-adherence to treatment and loss to follow- up, which can have serious consequences. When children and young people who use paediatric services are moving to access adult services these should be organised so that all those involved in the care, treatment and support cooperate with the planning and provision to ensure that the services provided continue to be appropriate to the age and needs of the person who uses services. Environment All hospital settings should meet the Standards for the Care of Critically Ill Children 169 Classification: Official Paediatric Cardiac Services Specification (Paediatric Intensive Care Society, London 2010). The National Minimum Standards for Providers of Independent Healthcare, (Department of Health, London 2002) require the following standards:  A16. There should be age specific arrangements for meeting Regulation 14 of the Health and Social Care Act 2008 (Regulated Activities) Regulations 2010. These require:  A choice of suitable and nutritious food and hydration, in sufficient quantities to meet service users’ needs;  Food and hydration that meet any reasonable requirements arising from a service user’s religious or cultural background  Support, where necessary, for the purposes of enabling service users to eat and drink sufficient amounts for their needs. For children, these should include specific arrangements that:  Ensures the medicines given are appropriate and person-centred by taking account of their age, weight and any learning disability  ensuring that staff handling medicines have the competency and skills needed for children and young people’s medicines management  Ensures that wherever possible, age specific information is available for people about the medicines they are taking, including the risks, including information about the use of unlicensed medicine in paediatrics. Providers should ensure that:  They are supported to have a health action plan  Facilities meet the appropriate requirements of the Disability Discrimination Act 1995  They meet the standards set out in Transition: getting it right for young people.

How can you tell the difference between cold and allergy symptoms? Use nasal washes to rinse allergens from inside the lining of your nose. Begin allergy medications and nasal sprays before the start of allergy season to reduce the severity of symptoms. You can develop seasonal allergies at anytime during your life. Cold symptoms rarely last more than two weeks, but allergies can last as long as you are exposed to the substance that is triggering the reaction. But perhaps the biggest clue that can help you distinguish between a cold and allergies is the duration of symptoms. Cold and allergies, by nose picking, or by getting hit in the nose. Nasal passages that are blocked by a cold or allergy can cause snoring. It is caused by pollen allergens in the air, including those of grasses and hay.

Reliever inhalers - used when needed to quickly relieve asthma symptoms for a short time. Try herbs such as butterbur (for nasal allergies), spirulina or nettle leaf; check with your doctor first.

Although you cannot cure” a pollen allergy, there are effective medications - both over-the-counter and prescriptions and allergy shots - that can bring symptom relief for most people. Other pollens such as ragweed and other weeds can produce allergy symptoms as early as August and continue through November. people have pollen allergies all year. This exposure to allergens improves your tolerance to pollen and reduces symptoms. People with asthma often see increased reactions when pollen counts are high. You might not be able to control your allergies completely, but you can do yourself a favor by avoiding anything that causes your allergy symptoms. Your doctor may send you to an allergist (say: AL-ur-jist), a special doctor who helps people who have allergies. With allergies, your nose and eyes itch. There are other differences between colds and allergies you can look for. If your cold symptoms last more than 2 weeks, you probably have an allergy instead of a cold. Some of these allergens cause sneezing, a runny nose, itchy eyes and ears, and a sore throat. When your immune (say: ih-MYOON) system reacts to one of these allergens and you have symptoms, you may be allergic to it. If your allergy skin test is positive, you have several options to prevent an allergic reaction from occurring again. Your doctor may ask you to stop taking some medications before the tests, such as antidepressants or antihistamines that may affect the allergy skin test results. The doctor may choose to do an allergy blood test along with the skin allergy test. Allergy skin tests are typically done on the back or the back of the arm, depending on the number of allergens being tested. This test is usually used to test for allergies to pollen, mould, pet dander, dust mites, and foods. Testing may also be necessary for people with potentially serious allergic reactions or asthma. An allergy skin test identifies which substance triggers an allergic reaction. So when we see a child with eczema, we know he is at higher risk to go on and develop asthma and allergic rhinitis.” However, Dr. Miller notes that the march is certainly not inevitable — there are plenty of cases where a child with eczema does not go on to develop either of the other conditions. Dr. Gendreau-Reid also notes that those who are born with an allergy to foods such as milk, eggs or peanuts are indeed predisposed to developing seasonal allergies as well. In what is known as the food/pollen syndrome,” people who are allergic to trees or grass pollen can also have a reaction to foods with the same molecular structure; for example, tree nuts such as hazelnuts or almonds, or even fruits such as peaches or apples. Having one parent with any type of allergy gives a child an approximately 30 percent chance of having allergies, and with two allergic parents, that probability increases to about 50 percent. The pollen can get in her hair, and it will get in her nose and eyes all night,” says Dr. Miller. Asthma and Allergy Foundation of America: Mold Allergy.” Cold symptoms and a fever of more than 102 F may be signs that you have the flu. Wheezing and shortness of breath can be caused by a cold or allergies if you have a respiratory condition, such as asthma or chronic obstructive pulmonary disease (COPD). If your coughing and sneezing is accompanied by an itchy, runny nose and itchy, watery eyes, chances are good that you have allergies. Which of the following is a symptom of both colds and allergies? DO YOU HAVE A FAMILY HISTORY OF HAY FEVER OR ALLERGIES? PLEASE NOTE: The information presented here is intended to provide readers with general information about seasonal symptoms and is not intended to provide specific medical advice, diagnosis or treatment. Question: Your symptoms include fever, body aches, sore throat and thick, colored nasal discharge. Whether you go for a walk, pet a dog, spend time gardening, or just go to check the mail, washing with soap and water can help remove pollen and pet dander. For someone with severe allergies, exposure to ozone or smog for even a short amount of time can cause worsening symptoms that are very uncomfortable. Being a severe allergy sufferer means that breathing in even a moderate amount dust or dust mites could cause your respiratory function to become impaired, your eyes to become irritated, or any other number of potentially bothersome symptoms. Maybe so. But doing this can help prevent pollen and mold spores from getting into your nose and mouth.

Surgical repair in these cases is easier as it only requires connecting this common collecting vein to the back of the left atrium cheap antabuse online mastercard medications may be administered in which of the following ways. Obstruction may occur in any type but is most common in the infradiaphragmatic type (obstruction occurring at the level of the diaphragm) and is less common with the cardiac type purchase antabuse 250 mg on-line medications quizzes for nurses. Felten Pathophysiology As mentioned above purchase antabuse with american express symptoms 24 hour flu, the presence of some atrial level communication is essential to provide right-to-left shunting buy 250 mg antabuse with visa symptoms your period is coming. Since all pulmonary and systemic veins ultimately drain into the right atrium, there is complete mixing of saturated and desaturated blood, which typically results in the same oxygen saturation in all cardiac chambers and thus arterial desaturation causing clinical cyanosis. The degree of cyanosis depends on the amount of pulmonary blood flow, which in turn depends on pulmo- nary vascular resistance and the presence of pulmonary venous obstruction. In severe cases of pulmo- nary venous obstruction pulmonary hypertension will result. On the other hand, if there is no or minimal obstruction to pulmonary venous drainage, pulmonary blood flow may be excessive and the patient can be well saturated (saturations >90%). The pul- monary venous obstruction causes significant pulmonary hypertension and pulmonary edema. As a result, infants are usually acutely ill within the first few hours after birth with severe cyanosis, tachypnea and respiratory distress. Untreated, these infants will deteriorate quickly and die within a short period of time. Findings on physical exami- nation include severe cyanosis, tachypnea and tachycardia. On cardiac auscultation, the first and second heart sound is louder than normal and a soft systolic murmur may be heard in the pulmonary area, although a murmur is often absent. These patients present with symptoms similar to a very large atrial septal defect shunt. More commonly, these patients are diagnosed as newborns due to the detection of a murmur or mild cyanosis. On physical examina- tion, these infants are thin, tachypneic and might be slightly cyanotic. The increased flow across the tricuspid valve results in a tricuspid stenosis-like murmur producing a diastolic rumble murmur at the left lower sternal border. In addi- tion, a systolic ejection murmur at the left upper sternal border can be heard due to increased flow across the pulmonary valve. It can determine the type of pulmonary venous drainage and presence or absence of obstruction to pul- monary venous return. If performed, it would reveal similar oxygen saturation measurements in all cardiac chambers. All other congenital heart diseases can be stabilized with prostaglandin infusions and/or balloon atrial septostomy (Rashkind procedure). Children with no obstruction to total anomalous pulmonary venous drainage are stable and actually tend to present at 1–2 months of age. Interventions that could help while awaiting surgery in sick patients include intuba- tion and mechanical ventilation while using 100% oxygen as well as correction of metabolic acidosis. The use of prostaglandins is controversial as it might help increase cardiac output by allowing right-to-left shunting across the ductus arteriosus but at the expense of further decrease in pulmonary blood flow. The repair involves creation of an anastomosis between the common pul- monary vein and the wall of the left atrium. Long-term potential complications include pulmonary venous obstruction at the site of anastomosis and arrhythmias. He also had history of recurrent upper respiratory infections and the mother reports that he breathes rapidly during feedings. He 19 Total Anomalous Pulmonary Venous Return 233 was born by normal vaginal delivery at term and was discharged from the hospital at 2 days of life. A 2/6 systolic ejection mur- mur was heard over the left upper sternal border and a 2/6 diastolic rumble murmur was heard over the left lower sternal border. Findings of auscultation reflect increased flow across the pulmonary valve producing a systolic ejection murmur and increased flow across the tricuspid valve resulting in diastolic rumble, which would be unlikely in cardiomyopathy. Moreover, left to right shunt lesions and cardiomyopathy should not present with this degree of cyanosis unless the patient were in severe heart failure due to signifi- cant pulmonary edema. Since this patient presents outside of the newborn period, it is likely to be a case where the anomalous pulmonary venous return is not obstructed, there- fore likely to be of the supracardiac, cardiac, or mixed types. Surgical repair is scheduled soon after the diagnosis is made to avoid the development of pulmonary and cardiac changes secondary to long stand- ing cyanosis and volume overload. She was born at term by normal vaginal delivery with no complications during pregnancy. The patient was intubated and placed on 100% oxygen and started on inotropic support. Early presentation secondary to a con- genital heart disease is unique to very few lesions, these are: • d-transposition of the great arteries: in this lesion the right ventricle pumps de- oxygenated blood to the aorta resulting in severe cyanosis, lower extremity oxygen saturation is slightly higher as shunting across the ductus arteriosus delivers some oxygenated blood to the descending aorta. On the other hand, patients with the rare variety of hypoplastic left heart syndrome associated with intact atrial septum are immediately and gravely ill at birth due to inability of pulmonary venous blood to drain out of the left atrium due to combination of mitral atresia and intact atrial septum, thus preventing delivery of oxygenated pulmonary venous blood. Pre- and post- ductal saturations in this case are the same since oxygenated and deoxygenated blood mixes in the right atrium resulting in identical oxygen saturations in all cardiac chambers. The patient can be kept on 100% oxygen, started on pressors and possibly on prostaglandins to try to increase the cardiac output, although prosta- glandins can further decrease the pulmonary blood flow and can be less helpful in this lesion. Meanwhile, emergent surgical repair is planned to reconnect the anoma- lous pulmonary venous drainage to the left atrium, which will bypass the obstructed region within the anomalous pulmonary venous connection. Hoffman Key Facts • Patients with truncus arteriosus have a significant probability of having DiGeorge syndrome. In this lesion, there is only one (truncus) artery receiving blood ejected from both ventricles. The pulmonary arteries emerge form the truncus as a main pulmonary artery which bifurcates into a right and left pulmonary arteries, or the 2 pulmonary arteries emerge separately from the truncus. Incidence Truncus arteriosus is rare, with a prevalence of 1–2% of all congenital heart defects. Pathology In truncus arteriosus, the heart has a single outlet through a single semilunar (truncal) valve and into a common arterial trunk. The defining feature of this common arterial trunk is that the ascending portion gives rise to all circulations: systemic, pulmonary, and coronary. The common arterial trunk usually overrides the crest of the ventricular septum, such that it has biventricular origin. Both ventricles are well-developed and in communication by a large ventricular septal defect, which is always present and roofed by the common arterial trunk. A single valve and great vessel overrides a ventricular septal defect, thus emerging from both ventricles. The pulmonary arteries arise from the ascending portion of the common arterial trunk in two main ways: – From a single orifice, with a main pulmonary artery segment of variable length, which then branches and gives rise to left and right pulmonary artery. The classifications based on the anatomic position of the pulmonary arteries are as follows: Type 1: There is a main pulmonary artery arising from the ascending portion of the truncus. Type 2: Both pulmonary arteries arise side by side in the posterior aspect of the truncus. Type 3: The pulmonary arteries arise opposite each other on the lateral aspects of the ascending truncus. Type 4: Also known as pseudotruncus is not a true type of truncus arteriosus since it represents pulmonary atresia with ventricular septal defect. The pulmonary arteries in this lesion arise opposite each other on the lateral aspects of the descending aorta, these vessels are in reality collateral vessels feeding pulmo- nary segments and not real pulmonary arteries. Stenosis at one or both branches of the pulmonary artery has been described, but is generally rare. Associated Anomalies In contrast to the normal aortic valve, the truncal valve may have from one to six leaflets. Most common is three leaflets (~60%), followed by four (~25%), and two (~10%), with one, five and six leaflets being quite rare. Furthermore, the valve leaflets may be thickened, dysplastic, fused, and of unequal size, and the truncal sinuses which support the valve leaflets are often poorly developed. A right aortic arch with mirror-image brachiocephalic branching is present in up to 35% of patients. A right aortic arch courses over the right mainstem bronchus and passes to the right of the trachea, in contrast to a left aortic arch, which courses over the left mainstem bronchus and passes to the left of the trachea. An interrupted aortic arch may be present (~15%), such that the common arterial trunk gives rise to the coronary circulation, to the ascending aorta which supplies the head and neck, and to a large ductus arteriosus which gives rise to the pulmo- nary arteries and continues on to supply the descending aorta. A branch pulmonary artery may be absent in up to 10% of patients, usually on the left if the aortic arch is left-sided, or on the right if the aortic arch is right-sided. Coronary artery anomalies are common in truncus arteriosus, and vary from unusual origin and course to stenosis of the coronary ostium. Pathophysiology In truncus arteriosus, outflow from both ventricles is directed into a dilated com- mon arterial trunk. Consequently, a mixture of oxygenated and deoxygenated blood enters systemic, pulmonary, and coronary circulations. The actual oxygen satura- tion in the common arterial trunk will depend on the ratio of pulmonary blood flow to systemic blood flow, with greater systemic oxygenation reflecting a greater mag- nitude of pulmonary blood flow. The magnitudes of pulmonary and systemic blood flow are determined by the relative resistances of the pulmonary and systemic vas- culature. In the newborn period, when pulmonary vascular resistance is high, pul- monary blood flow may be only twice as much as the systemic blood flow. As pulmonary vascular resistance declines in infancy, the magnitude of pulmonary blood flow relative to systemic blood flow increases and can be enormous, as flow into the lower resistance pulmonary vasculature occurs throughout systole and diastole. The torrential pulmonary blood flow returns to the left heart and imposes a significant volume overload with attendant increased myocardial work load, which eventually leads to congestive heart failure. There is both systolic and diastolic blood flow into the pulmonary arteries due to their origin from the truncus.
