Originating from the opposite sinus of Valsalva, an interarterial?course and an intramural course are especially considered as the risk factor for fatal cardiac events. Surgical indication remains controversial because many patients are asymptomatic. A 52-year-old man with anomalous origin of the right coronary artery with an interarterial?course concomitant with the left main trunk disease was resuscitated from cardiopulmonary arrest. It was likely to be attributed to the left main trunk disease, but anatomical structure of the right coronary artery suggests its possible involvement. Prophylactic bypass grafting for the right coronary artery was performed using saphenous vein graft without ligating native vessel to prevent future cardiac events, as well as revascularization of the left main trunk disease. All grafts were patent in one-year follow-up coronary angiography. Any cardiac event has not occurred.展开更多

We herewith present a case of early TRAS detected 6 hours after a successful renal transplant. Renal angiography showed complete stenosis of the internal iliac to renal artery anastomosis. Percutaneous transplant artery angioplasty was attempted, but was not successful;hence the surgical correction of the same was done. This is to demonstrate the use of saphenous vein bypass of anastomotic obstruction of the previous anastomosis, in case of short renal artery.展开更多

Peri-operative complications like dissection, stenosis involving coronary artery are well described in many series. We present a rare iatrogenic complication of disrupted left main coronary artery during the delivery of cardioplegia while performing AVR in a 54 year male patient for severe calcific aortic stenosis. The inadvertent injury to the artery was timely noticed and managed successfully with long saphenous vein graft.展开更多

TEE revealed normal size left ventricle with severely dilated left atrium. There was moderate aortic regurgitation and moderate aortic stenosis noted. Patient was incidentally found to have an abnormal vascular communication noted to the right atrium. To further evaluate this f inding, the patient underwent cardiac magnetic resonance angiography which revealed that the tubular structure noted on TEE was actually a graft that was abutting onto the coronary sinus, and the f low anomaly was really the graft coming up and running adjacent to the coronary sinus.展开更多
