Percutaneous Coronary Intervention of an Anomalous Left Main Coronary Artery Arising from the Right Sinus of Valsalva

Abstract

Anomalous origination of a coronary artery from the opposite sinus of Valsalva is an uncommon congenital anomaly. Intervention for concurrent coronary artery disease is challenging due to the location of the ostia, the takeoff of the vessel as well as the course of the artery in question. It is also important, where possible, to exclude a "malignant" course as the most common adverse outcome from this anomaly is that of sudden cardiac death. Here we present a case of percutaneous coronary intervention in a patient with anomalous left main origination from the right coronary sinus of Valsalva and a brief discussion on the subject.
