  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

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

  7. 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

  8. Patent ductus arteriosus

  9. 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

  10. Right-to-Left shunt

  11. 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

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

  13. Obstructive Defect

  14. 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
