Superdominant Right Coronary Artery with Absence of Left Circumflex and Anomalous Origin of the Left Anterior Descending Coronary from the Right Sinus: An Unheard Coronary Anomaly Circulation

Marcos Danillo Peixoto Oliveira et al. Case Rep Cardiol. 2015.

Abstract

Coronary artery anomalies are congenital changes in their origin, course, and/or structure. Most of them are discovered as incidental findings during coronary angiographic studies or at autopsies. We present herein the case of a 70-year-old man with symptomatic severe aortic valvar stenosis whose preoperative coronary angiogram revealed a so far unreported coronary anomaly circulation pattern.

Superior panel: cranial left anterior oblique view. Inferior panel: left anterior oblique view. RCA: right coronary artery.
