Absence of the right coronary artery with distal angulation of the left circumflex coronary artery

Excerpt

The incidence of coronary artery anomalies (CAAs) is 0.6–1.3 % [1], and a single coronary artery (SCA) is present in 0.02–0.06 % of the general population [2]. These patients are mostly diagnosed during autopsy or angiographic examination [1]. An absent left main coronary artery and an anomalous left circumflex artery (LCX) are the most common CCAs [3]. SCA originating from the aortic root and supplying the heart is a rare entity that is associated with sudden cardiac death in athletes [2]. Congenital absence of the right coronary artery (RCA) is an uncommon entity with few case reports in the literature. In the present case, we report on a female patient with an absent right coronary artery accompanied by an interesting course of the LCX and apical-midventricular ischemia of the inferolateral wall on myocardial perfusion imaging. …
