Common pulmonary vein


  • Gets incorporated into the left atrium
  • The common pulmonary vein gets incorporated into the left atrium (LA
  • Four pulmonary veins individually connect directly to the left atrium.
  • Failure of the common pulmonary vein or atresia early in its development, while the persistent of the connections between systemic and pulmonary vasculature, leads to the development of TAPVC.
  • If only a portion of the common pulmonary vein, either right or left, becomes atretic, persisting pulmonary-systemic venous connections form PAPVC.
