title: Transcatheter closure of patent vertical vein after repair of total anomalous pulmonary venous connection.
abstract: BACKGROUND
  Vertical vein is left patent in some cases of supra-cardiac total anomalous pulmonary venous connection (TAPVC) when there is hemodynamic instability due to noncompliant left atrium and ventricle. After the peri-operative period, this results in features of pre-tricuspid shunt.
  
  
  METHODS
  Three cases with patent vertical vein following repair of supra-cardiac TAPVC presented with features of pre-tricuspid shunt on follow-up. Trans-catheter closure of patent vertical vein was performed using vascular plug in all three subjects.
  
  
  RESULTS
  The procedure was technically successful in all the patients. There was a complication related to catheter tip breakage in one of them, which was successfully managed. There was no impingement on pulmonary vein in any of the patients.
  
  
  CONCLUSIONS
  Patent vertical vein following TAPVC repair results in features of pre-tricuspid shunt. Transcatheter closure of the patent vein is feasible.
