1 Congenital Heart Disease
Dr. Raid Jastania

2 Congenital Heart Disease
8 per 1000 live birth Could be minor defect or major defect Cause – unknown Genetic: chromosomal anomalies, trisomy 13, 18, 21 Environmental: infections, rubella Types: Left-to-Right shunt Right-to-Left shunt Obstructive defects

3 Left-to-Right Shunt

4 Left-to-Right Shunt Most common ASD, VSD, PDA
May be asymptomatic at birth Cyanosis is not early feature

5 Atrial Septal Defect 75% ostium secondum ASD 15% ostium primum ASD
10% sinus venosus ASD


7 Atrial Septal Defect Diagnosed usually in adulthood
Left to right shunt Right atrial dilatation, right ventricular hypertrophy Pulmonary hypertension Late: Cyanosis (Eisenmenger syndome) CHF


9 Ventricular Septal Defect
70% in the membarneous region Most common congenital heart disease Many VSD close spontaneously Left to right shunt Right ventricular hypertrophy/dilatation Dilated pulmonary artery Pulmonary hypertension Late: CHF, cyanosis


11 Patent ductus arteriosus

12 Patent ductus arteriosus
Ductus arteriosus closes after birth by Increase arterial oxygen Drop in pulmonary vascular resistance Decrease in prostaglandin E2 PDA leads to Left to right shunt Left atrial and left ventricular hypertrophy Pulmonary hypertension – atherosclerosis and right ventricular hypertrophy Machinery murmur Late: Cyanosis, CHF


14 Right-to-Left shunt

15 Tetralogy of Fallot Most common cyanotic congenital heat disease
Consist of: VSD Over-riding Aorta Pulmonary stenosis Right ventricular hypertrophy Boot shape heart Right to left shunt Pulmonary hypertension does not occur


17 Transposition of Great Arteries
Aorta from the right ventricle Pulmonary artery from the left ventricle + PDA, ASD, VSD Cyanosis


19 Obstructive Defect

20 Coarctation of Aorta Narrowing of the aorta Preductal coarctation
Before ductus arteriosus Right ventricualr hypertrophy Selective cyanosis of lower extremities Postductal coarctation Left ventricular hypertrophy Hypertension of upper extremities Weak pulse of legs
