The contrast was seen in the coronary sinus, which was draining towards the right atrium.
Care was taken that this incision passed through the commissure between non-coronary and the left posterior coronary sinus. The wall of the aorta was flattened to visualize the sinu-aortic ridge, the cusps, number and position of the coronary ostia.
Echocardiography showed a slightly enlarged left ventricle (57 mm) with significant widening of the aortic root, a thin right coronary sinus with extension into the distal right ventricular outflow tract, and a 1.4 cm diameter defect in the upper part of the outflow tract.
More anteriorly located right coronary sinus (RCS) gives rise to the right coronary artery (RCA) and the left main coronary artery (LMCA) arises from more cephaladly located the left coronary sinus (LCS) (Fig.

Catheter ablation procedures to eliminate A-V nodal reentrant tachycardia place the slow pathway in the posteroinferior aspect of the right atrium in an area adjacent to the coronary sinus, (6) and Fisch and Knoebel cite evidence that the slow pathway contains specialized A-V node-like tissue that is under the influence of the vagus nerve.

Yamanaka and Hobbs reported that of all the people undergoing coronary angiography, anomalous coronary arteries are detected in only about 1.3%.1 Anomalous right coronary artery (RCA) from the left coronary sinus is reported to have an incidence of 0.13%.2 These anomalies are mostly benign and are often detected upon routine cardiac catheterizations.
