To determine the clinical outcome of patients requiring emergency repeat coronary artery bypass graft (CABG) procedures, we reviewed 23 such procedures performed for ongoing myocardial ischemia refractory to medical management. The operative mortality was 17%. On follow-up, an average of 24.9 months after emergency reoperation, 14 of the 19 survivors (74%) had recurrent angina. As compared to a randomly selected group of 25 patients who underwent elective repeat CABG procedures during the same time period, the incidence of late cardiac events was significantly higher (79% in the emergency group, 30% in the elective surgery group) and fewer patients had received internal mammary artery (IMA) grafts (9% vs 52%). Emergency repeat CABG operations have considerable operative mortality and poor postoperative functional results with the majority of survivors developing recurrent ischemic syndromes within a short period of time.
