Between 1971 and 1988 left thoracotomy was performed on pump for selected reoperations. Since 1993, 92 patients were operated on with a limited approach and an increased number of cases were done off pump (70 patients). The purpose of this paper is to describe the transition of our operative techniques from on pump to off pump for reoperative coronary patients. From 1995 to 1999, 22 patients (Group 1) were operated on pump and 70 patients (Group II) off pump; 86 of 92 (93.5%) had reoperations. The demographic data were similar in these two groups regarding age, gender, ejection fraction, and total number of grafts performed. In this study 92 patients had a crude mortality of 4.3%. Limited access thoractomy provides safer reoperation than previously (1971-1988) with an improved on or off pump (4.5% vs. 4.3%) mortality, compared to the on pump mortality of 10% between 1971-1988. Off-pump operations are performed with increasing frequency and with the same risk and less postoperative complications.
