Angiogram of the month Successfully treated sudden cardiac arrest in a patient with single coronary artery originating from the right coronary sinus

Abstract

Congenital abnormalities of coronary arteries may predispose to life-threatening sudden cardiac events. We present a case of aborted sudden cardiac death in a patient who was diagnosed as having single coronary artery originating from right coronary sinus. The vessell divided into critically stenosed left main trunk and significantly narrowed right coronary artery. The patient was successfully treated with coronary artery bypass grafting preceded by implantation of ICD device.
