Transcatheter occlusion of an anomalous origin of left coronary artery from pulmonary artery in an adult as an alternative to surgery.

Anomalous origin of the left coronary artery from the pulmonary artery causes heart failure and death in infancy. In rare adult survivors with well-developed collaterals, surgical left coronary ligation to arrest steal is often combined with bypass grafting. Transcatheter left coronary artery closure in a symptomatic adult as an alternative to surgical ligation resulted in complete resolution of inducible ischaemia on myocardial perfusion imaging.
