Sequential, bilateral and free mammary grafts are employed in the current operative treatment of coronary pathology to maximize the benefit of the enhanced long-term patency of the internal mammary graft. This study reports the early and late results of a consecutive series of 364 patients in whom an internal mammary artery jumpgraft was performed. The total perioperative mortality was 1.6%, the cardiac perioperative mortality 1.0%. The perioperative infarct rate was 2.5%; the infarct rate in the mammary outflow field 1.4%. The total survival at 90 months (operative mortality included) was 92.2%, the cardiac survival at 90 months was 95.8% and the event-free group of the operative survivors was 85.2% at 90 months. The mammary artery jumpgraft can be performed without additional risk to the patient, it has a very good late result and it should be standard tool in the current coronary surgery technique. It is essential in coronary redo surgery and in patients after bilateral saphenectomy.
