Background - Minimally invasive coro3nary artery bypass (MIDCAB) is a new surgical technique by which the left internal mammary artery is anastomosed under direct visualization to the left anterior descending artery without cardiopulmonary bypass. Methods and Results - We followed all 274 patients who underwent MIDCAB from the time it was introduced at a single center. In-hospital and 1-year clinical events were source-documented and adjudicated. The in-hospital major acute cardiac event rate was 2.2%; this included a 1.1% mortality rate. At 1 year, the respective rates were 7.8% and 2.5%. When compared with the initial 100 procedures, the subsequent 174 procedures had shorter vessel occlusion times (10±5 versus 14±6 minutes; P=0.009), times to extubation (6±3 versus 14±10 hours; P<0.001), and lengths of hospital stay (2.1±1.9 versus 3.2±3.1 days; P=0.04). Cumulative 1-year adverse cardiac events were 11% in the initial 100 cases and 6% in the subsequent 174 cases (P=0.17). Conclusions - Excellent clinical results can be achieved with the MIDCAB technique. The clinical adverse event rate may decrease with accumulated experience.
