Dual-artery stenting of a type III single coronary artery from right aortic sinus.

A single coronary artery presenting with stenosis in two of the three vessels arising from a common ostium is a rare anomaly Lipton et al. proposed a classification, which was modified by Yamanaka and Hobbs. In our case, a single coronary artery was giving rise to the LAD, left circumflex (LCx), and the right coronary artery (RCA). There was 80% stenosis in the ostium of the LCx. The RCA in the mid and distal segment had stenosis of 80% and 70%, respectively. We were able to successfully stent the three stenotic segments.
