CONTENT Definition of Congenital cyanotic heart disease Evaluation of Criticlly Ill Neonate with Cyanosis Classification of Congenital cyanotic heart disease Tetralogy of Fallot Pulmonary atresia with VSD Double outlet right ventricle with PS Pulmonary atresia Tricuspid atresia Ebstein's Anomaly
Congenital cyanotic heart disease It is abnormality in cardio circulatory structure that present at birth. CHD occurs in about 8/1000 live births, and those with critical CHD are 2/1000 live births. Prompt diagnosis and treatment of CHD significantly decrease mortality and prevent secondary damage to other organ systems.

Tetralogy of Fallot It is a condition caused by a combination of four heart defects that are present at birth. These defects are: Pulmonary Infundibular Stenosis Overriding aorta ventricular septal defect (VSD) Right ventricular hypertrophy,
Tetralogy of Fallot.
Tetralogy of Fallot hypercyanotic spells: Sometimes, babies with tetralogy of Fallot will suddenly develop worsen of central cyanosis after crying, feeding or having a bowel movement. It is treated by placing child in the knee-to-chest position, oxygen,morphine and propranol. systolic thrill over left sternal border Single second sound Ejection systolic murmur(PS) Treated by: Total correction or The Black-Taussig operation
Tetralogy of Fallot boot-shaped heart
Pulmonary atresia with VSD Pulmonary atresia with ventricular septal defect (PA-VSD) is a cyanotic congenital heart disease characterized by underdevelopment of the right ventricular (RV) outflow tract with atresia of the pulmonary valve and a large ventricular septal defect (VSD),
Pulmonary atresia with VSD
A prominent a wave in the jugular pulse may be found. auscultation: systolic murmur usually is audible along the lower left sternal border. A continuous murmur is best heard over the upper chest in the presence of a PDA. If systemic-to-pulmonary collateral arteries are present, continuous murmurs may be diffusely audible over the entire chest and back. Treatment: prostaglandin E 2 is often required to keep the ductus arteriosus open Most babies will need a 'Shunt' operation during infancy
Double outlet right ventricle with PS Double outlet right ventricle (DORV) is a congenital heart disease in which the aorta rises from the right ventricle instead of from the left ventricle Both the pulmonary artery and aorta come from the same pumping chamber. No arteries arise from the left ventricle.
Double outlet right ventricle with PS
Double outlet right ventricle with PS initial medical management consists of increasing the fraction of inspired oxygen (FIO 2 ), which may be up to 100%. This decreases pulmonary vascular resistance, thereby increasing the amount of blood flow in the lungs Surgical treatment create a tunnel through the VSD. The tunnel connects to the aorta.
Pulmonary atresia Pulmonary atresia with intact ventricular septum (PA/IVS) is a condition in which the valve that allows blood to flow from right ventricle of heart to lungs (pulmonary valve) hasn't formed properly or is closed (atresia). PA/IVS is a rare congenital heart disease present from the early stages of a baby's heart development
Pulmonary atresia systolic thrill over pulmonary area prostaglandin E1 is usually used to help the blood move into the lungs. Open heart surgery to repair or replace the valve
Tricuspid atresia Tricuspid atresia is the third most common form of cyanotic congenital heart disease, The deformity consists of a complete lack of formation of the tricuspid valve with absence of direct connection between the right atrium and right ventricle.
Tricuspid atresia single second sound giant A wave murmer of VSD(+PDA) prostaglandin E 2 is often required to keep the ductus arteriosus open in the early neonatal period until surgery can be performed. Surgical treatment: The Fontan operation
Ebstein's Anomaly Ebstein's anomaly is a condition in which the tricuspid valve is malformed and sits lower than normal in the right ventricle. This condition is associated with right ventricle dysfunction, and commonly atrial septal defect or patent foramen ovale.
Ebstein's Anomaly =
Jugular venous pulse Large a and v waves late in the course of the disease, First heart sound is widely split with loud tricuspid component Third and fourthheart sounds are commonly present Medical Care Antibiotic prophylaxis for infective endocarditis Medical therapy for heart failure - Angiotensin-converting enzyme (ACE) inhibitors, diuretics, and digoxin Surgical Care Surgical care includes correction of the underlying tricuspid valve and right ventricular abnormalities heart sounds are commonly present
Critaria CCHD with increased pulmonary blood flow Poor feeding Recurrent chest infection Recurrent heart failure Increase P2 Chest x ray show plethora
Transposition of the great vessels Def:Transposition of the great vessels is acongenital heart defect in which The two major vessels that carry blood away from the heart -- the aorta and the pulmonary artery -- are switched (transposed).
Investigation. Chest x-ray
Total anomalous pulmonary venous return Def:Total anomalous pulmonary venous return is acongenital heart disease) in which none of the four veins that take blood from the lungs to the heart is attached to the left atrium (left upper chamber of the heart)
Double outlet right ventricle with out pulmonary stenosis
Investigation Chest x-rays :no pulmonary stenosis will cause increase pulmonary blood flow resulting in cardiomegaly with increase pulmonary vascular markings. The mediastinum may be narrow due to malposed great vessels.
Truncus arteriosus (TA) is an uncommon congenital cardiovascular anomaly that is characterized by a single arterial trunk arising from the normally formed ventricles by means of a single semilunar valve (ie, truncal valve).
Classification .Truncus arteriosus type I is characterized by origin of a single pulmonary trunk from the left lateral aspect of the common trunk, with branching of the left and right pulmonary arteries from the pulmonary trunk. .Truncus arteriosus type II is characterized by separate but proximate origins of the left and right pulmonary arterial branches from the posterolateral aspect of the common arterial trunk.
Type3,4 .In truncus arteriosus type III, the branch pulmonary arteries originate independently from the common arterial trunk or aortic arch, most often from the left and right lateral aspects of the trunk. This occasionally occurs with origin of one pulmonary artery from the underside of the aortic arch, usually from a ductus arteriosus. .Type IV truncus arteriosus, originally proposed by Collett and Edwards as a form of the lesion with neither pulmonary arterial branch arising from the common trunk, is now recognized to be a form of pulmonary atresia with ventricular septal defect rather than truncus arteriosus.
Double inlet left ventricle
hypoplastic left heart syndrome (HLHS), In hypoplastic left heart syndrome (HLHS), the heart’s left side — including the aorta, aortic valve, left ventricle and mitral valve — is underdeveloped.
Heterotaxy Syndrome Heterotaxy syndrome is a rare birth defect that involves the positionof the heart and other organs. nt
“right atrial isomerism” and “left atrial isomerism” In a normal heart, the left atrial appendage looks different than the right. In heterotaxy syndrome, the two appendages look similar.
Asplenia Asplenia or right atrial isomerism: Children with this condition have multiple heart defects. They may have septal defects and problems with heart valves, particularly the pulmonary valve. The spleen may be absent (asplenia), and the liver and other organs may be on the wrong side of the body.septal defects
polysplenia Polysplenia or left atrial isomerism: Children with this condition may have septal defects as well as problems with heart valves and the heart’s electrical system. The spleen may be absent, or there may be several small spleens (polysplenia), instead of one spleen.
