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.
