Transseptal course of anomalous left main coronary artery originating from single right coronary orifice presenting as unstable angina
Abstract
Transseptal course of coronary artery has often been described as a benign entity; however, this report and literature analysis provides growing evidence of high risk of serious cardiovascular events in this anomaly. We present a case of unstable angina in a patient with anomalous common origin of left and right coronary arteries from a single coronary ostium at the right sinus of Valsalva, with subsequent transseptal course of the left main artery, review of relevant literature, and discussion of possible management options. Keywords: Transseptal course, Intramyocardial course, Intraseptal course
