Unusual case of single coronary artery with anomalous RCA from LAD: The ultimate of cardiac CT

Abstract

Coronary artery anomalies are found in 0.6%–1.55% of patients who undergo coronary angiography, and the increasing use of diagnostic coronary angiography is unveiling even more complex coronary anomalies. We report an interesting rare case of a single coronary artery from the left coronary sinus with anomalous origin of the right coronary artery from the mid-segment of the left anterior descending coronary artery. Such a variant case of a single coronary artery is not reported on computed tomography (CT) scan coronary angiography to the best of our knowledge.
