Spontaneous Coronary Artery Dissection in Hyperdominant Left Anterior Coronary Descending Artery

Abstract

A hyperdominant left anterior descending coronary artery variation is a rare but important diagnosis because of the risk for large-territory ischemia. We describe a very rare presentation of spontaneous coronary artery dissection in the distal portion of a hyperdominant left anterior descending coronary artery. No similar cases have been described.
