19-year patency of a coronary-coronary venous bypass graft.
No data are available on the long-term outcome of coronary-coronary venous bypass grafting. We describe a case in which we successfully stented a discrete, critical stenosis of a coronary-coronary venous graft that had been placed 19 years earlier to minimize manipulation of a severely calcified ascending aorta. Coronary-coronary bypass grafting should be considered in cases involving severe aortic calcification, in situ grafts of inadequate length, and stenosed or occluded subclavian arteries. Such a bypass can be performed with either saphenous vein or arterial conduits, and it provides a flow rate similar to that of aortocoronary bypass. This option could be borne in mind as a 2nd-choice technique for the durable restoration of coronary blood flow in selected cases.
