In this video, Dr. O P. Yadava, Chief Cardiac Surgeon, National Heart Institute talks about total arterial bypass surgery. Whenever a bypass surgery is done, only arterial conduits are used which is then known as total arterial myocardial revascularization. It can be performed using various configurations. Free grafts, in situ grafts, single grafts or sequential grafts are used in bypass surgery. In sequential grafts, one conduit can be used to bypass two arteries. Dr. Yadava will also describe that a free graft can be attached to a pedicle graft and can do T or Y configuration of total arterial revascularization known as T or Y grafts.
