Congenital heart disease producing heart failure after age 1 to 2 weeks of age

  1. VSDs and AV septal defects
  2. TGA
  3. Truncus arteriosus
  4. Total anomalous pulmonary venous connection

Why VSD, TGA and Truncus arteriosus cause heart failure usually after the age of 1 to 2 weeks of age but not at birth?


  • After age 1 to 2 weeks pulmonary vascular resistance reduce.
  • This allows substantial left-to-right shunting
  • Increased Left to Right shunt cause heart failure
  • So heart failure is more common inthis period.
