Anomalous Origin of Left Main Coronary Artery from the Right Sinus of Valsalva

Abstract

Anomalous coronary arteries are rare congenital variations with cases ranging from asymptomatic to life-threatening. Given the wide variability of coronary anomalies, it is challenging to predict their clinical consequences. Here, we present the ‘malignant’ variant – interarterial course of the left coronary artery between the aorta and pulmonary trunk – given the highest risk of sudden cardiac death among the various coronary anomalies. Learning Objectives: 1. To describe the ‘malignant’ interarterial course of the left coronary artery and its association with sudden cardiac death 2. To present the various surgical options recommended to patients with this variant
