Correction of Tetralogy of Fallot Associated With Anomalous Coronary Artery Without Extracardiac Conduit.

Abstract

Between 1983 and 2016, we operated on 14 children with tetralogy of Fallot with an anomalous coronary artery crossing the pulmonary infundibulum, which is an anomaly that makes the repair complex. The technique used was the enlargement of the right ventricular outflow tract underneath the mobilized coronary artery. All patients had right ventricular outflow tract relief without coronary artery injury. Only one patient required the use of an extracardiac conduit. There was neither in-hospital mortality nor coronary anomaly requiring reintervention. Mobilizing the anomalous coronary artery in tetralogy of Fallot repair often allows relief of obstruction without using an extracardiac conduit.
