Anomalous aortic origin of a coronary artery: a universally applicable surgical strategy

Abstract

The most commonly reported coronary arterial malformation, in accounts of sudden deaths, is anomalous aortic origin of a coronary artery. Anomalous coronary arteries may arise from the left, right, or non-coronary sinuses of Valsalva. Importantly, although the left coronary artery from the right sinus has the worst prognosis, sudden death has been reported in all variants of origin from the various sinuses of Valsalva. This paper describes a technique that addresses all of the problems relating to anomalous aortic origin of a coronary artery from the wrong sinus of Valsalva. This technique includes the transection of the ascending aorta and pulmonary trunk, coronary arterial enlargement with a pericardial patch, and lateral translocation of the pulmonary trunk to the left pulmonary artery. Anomalous aortic origin of a coronary artery from the wrong sinus of Valsalva is a potentially lethal cardiac anomaly that can be corrected in all cases using this simplified surgical technique that addresses the major anatomic and physiological problems.
