Saphenous vein bypass grafts were performed in 14 patients as a secondary cardiac operation. An indirect myocardial revascularization had been the initial procedure in five cases, an aortic valve replacement by prosthesis in three, and prior vein graft bypass in six. There were no hospital deaths, although one patient died during the 4- to 34-month follow-up period. While the condition of 11 patients has improved, 2 failed to benefit from the operation, and 1 of them subsequently underwent cardiac transplantation.
