Congenital single coronary artery: a rare anomaly.
J Dow Uni Health Sci Jan ;2(3):115-7.

Congenital coronary artery anomalies (CAAs) affect approximately 1% of general population undergoing coronary angiography. The incidence of single coronary artery is very rare specially in the absence of any structural heart disease and accounts for 0.024% – 0.044% of cases. This case report describes a single coronary artery arising from right aortic cusp which was trifurcating into right coronary artery (RCA), circumflex artery (CX) and left anterior descending artery (LAD). The left anterior descending (LAD) followed a malignant course between main pulmonary artery and aorta making it vulnerable to ischaemia. The advantage of multi detector computed tomographic angiography (MDCTA) lies primarily in its high diagnostic and anatomic accuracy because of its three dimensional (3D) capability and flexible post processing.
