Abstract:
We reviewed 223 cases of isolated coronary artery bypass grafting (CABG) during the past 6 years, and used the EuroSCORE to assess the differences in clinical outcomes between off-pump CABG (OPCAB) and on-pump CABG (conventional CABG: CCABG). After March 2000, our first choice has been OPCAB, with CCABG selected only for cases with unstable hemodynamics. The total of 223 isolated CABG cases consisted of 129 OPCAB and 94 CCABG, but after March 2000, 94 OPCAB and 42 CCABG were performed. Mean EusoSCORE was 5.8 for OPCAB and 4.1 for CCABG, and corresponding expected survival rates were 7.20% and 5.04%. The 3 cases of hospital death (mortality, 1.3%) all belonged to the earlier CCABG groups and were not related to cardiac death. After March 2000, no hospital deaths occurred in either group. Midterm results showed 5 deaths, but these were not related to cardiac death, either. There were no significant differences between the 2 groups in terms of hospital complications other than long mechanical ventilation time, which was markedly longer only for the OPCAB groups (p<0.01). Mean number of grafts was significantly high for patients in the CCABG groups (OPCAB 2.1 vs. CCABG 2.8; p<0.05). We have therefore been using OPCAB for high-risk cases, and midterm results of our CABG patients were satisfactory.
