The "omega-anastomosis": a new revascularization technique for coronary bifurcations

Ann Thorac Surg. 2003 Sep;76(3):954-5. doi: 10.1016/s0003-4975(02)05025-7.


We report the "omega-anastomosis," a new technique permitting the revascularization of both coronary branches beyond a bifurcation by using a single arterial graft. This technique consists of a longitudinal incision in the main coronary artery, which extends to both coronary branches beyond the bifurcation. The arterial conduit's distal extremity is cut vertically and tailored to produce a "bipetal" shape, which is used to enlarge and create an acceptable roof for both coronary branches beyond the bifurcation.
