الوصف: Purpose Off-pump coronary arterial bypass grafting (OPCAB) has become a common practice for coronary artery bypass grafting (CABG) in Japan, with approximately 65% CABG procedures currently being performed using OPCAB. However, it is unclear whether OPCAB is superior in terms of associated mortality, incidence of complications, graft patency rate, and long-term outcomes compared with conventional CABG (CCABG). Methods Literature consideration was performed, mainly based on observational studies involving large samples and randomized controlled trials (RCTs). Results Many RCTs indicated that the acute-phase and long-term mortality rates were comparable between CCABG and OPCAB or that OPCAB was inferior to CCABG. In contrast, many observational studies indicated that OPCAB was superior to CCABG. Conclusion CABG is a delicate procedure, the outcomes of which vary in accordance with the patient's condition as well as the level of expertise of the associated institution and surgeon. In the future, we hope that reports will emerge with excellent results, including long-term results, from Japanese institutions experienced in performing OPCAB.

الوصف: Background Multiple studies have compared on-pump coronary artery bypass (ONCAB) grafting with off-pump coronary artery bypass (OPCAB) grafting, but the optimal surgical strategy has yet to be established. Furthermore, there is limited evidence regarding mid-term graft patency rates. Methods Between April 2001 and March 2014, 365 consecutive patients underwent isolated coronary artery bypass grafting (CABG; male: 75%; mean age: 69 ± 10 years). After propensity-score-matched analysis, we assessed the results of 67 patients in each group (ONCAB: group A, OPCAB: group B). The mean follow-up period of graft patency and survival rate was 35 ± 37 months and 54 ± 47 months, respectively. Results There were no significant differences in baseline characteristics between the two groups. There was a trend for an increased number of distal anastomoses in group B as compared to group A (group A vs. group B: 3.8 ± 1.1 vs. 4.1 ± 1.6, P = 0.17). The total graft patency rate was tend to be lower in group A, but not statistically significant (group A: 156 months, 45.2%; group B: 96 months, 72.6%; P = 0.21). There was no difference for survival and major-adverse-cardiac-and-cerebrovascular-events (MACCE) free rate (P = 0.42 and 0.76, respectively). Conclusion Propensity-score-matched analysis revealed no difference in mid-term survival rate, MACCE free rate, graft patency rates, and number of distal anastomoses between ONCAB and OPCAB groups.
