Abstract
- Background: Off-pump coronary artery bypass (OPCAB) is performed worldwide, but significant risks are associated with conversion to on-pump surgery. Therefore, we evaluated the composite outcomes between an OPCAB group and a conversion group. Methods: From January 2008 to December 2012, 100 consecutive patients underwent OPCAB at Hallym University Sacred Heart Hospital, of whom 84 underwent OPCAB without adverse events (OPCAB group), and 16 were converted to on-pump surgery (conversion group). Early morbidity, early and long-term mortality, and major adverse cardiac and cerebrovascular events (MACCEs) were the primary and long-term composite endpoints. Results: The mean follow-up period was 55±26 months, with 93% of the patients completing follow-up. The composite outcomes in the OPCAB and conversion groups were as follows: early morbidity, 2.3% versus 12.5%; early mortality, 4.7% versus 0%; long-term mortality, 14.3% versus 25.0%; and MACCEs, 14.3% versus 18.8%, respectively. No composite endpoints showed statistically significant differences. Preoperative acute myocardial infarction (AMI) was identified as an independent risk factor for conversion (p=0.025). Conclusion: The conversion group showed no statistically significant differences in early mortality and morbidity, MACCEs, or long-term mortality compared with the OPCAB group. The preoperative diagnosis of AMI was associated with an increased number of conversions to on-pump surgery.
