Computed Tomography (CT) coronary angiography revealed the left main coronary artery with anomalous origin from the right coronary Valsalva sinus and an initial pathway between the aorta and pulmonary arteries, where there was significant luminal reduction (close to 50%) at rest, absence of atherosclerosis or luminal reduction in the other coronary arteries, and total calcium score of zero (Figure 1).
The anomalous origin of the left main coronary artery in the right Valsalva sinus can be classified into 4 types, based on its path: (a) pathway between the aorta and the pulmonary trunk, (b) pathway anterior to the exit of the right ventricle, (c) pathway through the supraventricular intramyocardial or subendocardial ridge, and (d) posterior pathway to the aortic root [23].
Catheterization at that time revealed anomalous right coronary artery originating from the left Valsalva sinus with moderate proximal obstruction and the patient received medical treatment.
(a) Normal left coronary artery; (b) proximal occlusion of anomalous right coronary artery (black arrow) originating in the left Valsalva sinus.
