Introduction.
Congenital anomalies and variations of the coronary arteries (CAA) are present at birth but can remain symptomatically silent for life, being discovered accidentally during interventional radiological procedures or whose discovery is prompted by cardiac chest pain. In the published note, their overall prevalence is approximately 1.3%. CAAs can be benign or malignant. Benign variations include 1) origination of the left anterior descending and left circumflex arteries from the left sinus of Valsalva (LSV), 2) the circumflex artery originating from the right coronary artery or right sinus of Valsalva (RSV) and 3) ectopic origin of the right coronary artery from the ascending aorta (1). The most common malignant variation of the coronary arteries is the ectopic origin of the right coronary artery from the LSV, which demonstrates a single coronary artery, beginning from the aortic trunk via a single coronary arterial ostium, acting as the primary blood supply to the heart (2). Here, we present a case of ectopic origin of the right coronary artery from the left sinus of Valsalva.
