Limited Access Left Thoracotomy for Reoperative Coronary Artery Disease: On or Off Pump (original) (raw)

2010, Journal of Cardiac Surgery

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 t o describe the transition of our operative techniques from on pump t o off pump for reoperative coronary patients. From 1995 t o 1999,22 patients (Group 1) were operated on pump and 70 patients (Group Ill 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 o n or off pump (4.5% vs. 4.3%) mortality, compared t o 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.
