Anomalous left coronary artery from the pulmonary artery: Modified extra-anatomic reimplantation

Abstract

The anomalous origin of the left coronary artery from the pulmonary artery in the position of a non-facing coronary sinus is extremely rare. The anatomical position of the ectopic ostia will determine which is the appropriate operative approach to create a dual-coronary supply. This report describes a technique of modified extra-anatomical rerouting using autologous pericardium patch and pulmonary artery flap to create a neo-composite coronary trunk passing anterior to the right ventricular outflow tract.
