OBJECTIVES: Over the past few years, great strides have been made in off-pump coronary surgery. This progress is due to a combination of the advances in surgical techniques and the development of instruments that make it possible to perform this procedure in the most varied situations. This is a retrospective study, the purpose of which is to assess our experience with this procedure over the last eleven and a half years. The authors underscore the rapid progress of the method in recent years and report on its indications, contraindications and results. METHODS: In the period from August 1991 to December 2003, 3,410 consecutively patients suffering from angina pectoris were submitted to off-pump coronary surgery. Ages ranged from 13 to 93 years, with a mean of 63 ± 12.0 years. Males accounted for 58% of the cases. The angina was rated according to the criteria of the Canadian Cardiovascular Society, 6.1% of the patients being in Class I, 6.8% in Class II, 46.3% in Class III and 40.8% in Class IV. RESULTS: Intraoperative mortality was low (0.4%). Hospital mortality (30 postoperative days) was 2.5%. Mortality and morbidity among the octogenarian patients were extremely low compared with patients operated on with cardiopulmonary bypass (CPB) (2.2% versus 12.6%) (p
