Single Coronary Artery from Right Sinus of Valsalva: A Single Center Experience of Seven Cases

Figure 2

(a)–(c): CAG showing the origin of all 3 major coronaries from the right sinus of Valsalva. Dominant RCA showing 80–90% long tubular stenosis in mid to distal part along with 80% stenosis in proximal PDA. LMCA originates from the right sinus via common ostium with RCA and coursed retroaortic and then divided into LAD and LCX. LAD had long segment calcific 80% stenosis and LCX was distal diseased. (Case 3). (d)–(f): CAG showing single vessel disease with all 3 major coronaries originating from the right sinus via common ostium. LCX ran retroaortic with ostioproximal 95% thrombotic occlusion. LAD had mild plaque. Dominant RCA had 60% stenosis in the mid part. (Case 4). (g) & (h): CT coronary showing all 3 major coronaries LAD, LCX, and RCA arising from the right sinus via the common trunk. RCA showed 90% stenosis in the mid part. (Case 5). (i) & (j): CAG showing anomalous origin of LMCA from the right sinus along with RCA via common ostium. The left main coronary traversed retroaortic towards the left side and divided into the LAD and LCX branches. A small diagonal branch originated from the left sinus. (Case 6). (k): CAG showing all 3 major coronaries LAD, LCX, and RCA originating from the right coronary cusp via the common ostium. (Case 7).
