BackgroundLong-term outcomes of Off-Pump Coronary Artery Bypass Grafting (OPCAB) as an alternative to the traditional Coronary Artery Bypass Grafting (CABG) technique with cardiopulmonary bypass (CPB) are not well defined.AimTo compare 10-year survival of isolated OPCAB versus CABG with CPB.Material And MethodsAnalysis of information obtained from databases, clinical records and surgical protocols of patients treated with isolated CABG between January 2006 and November 2008 at a Regional Hospital. Of 658 isolated CABG, 192 (29.2%) were OPCAB and 466 (79.9%) CPB. Propensity Score Matching (PSM) was performed to compare both groups. After PSM, two groups of 192 cases were obtained. Mortality data was obtained from the Chilean public identification service. Ten-year survival was calculated and compared with Kaplan-Meier and log-rank methods.ResultsFollow-up data was obtained in all cases. No statistically significant differences were found when comparing 10-year survival between OPCAB versus CPB (78.6% and 80.2% respectively, p 0.720). There was also no statistical difference in cardiovascular death free survival (90.1% with CPB versus 89.1% OPCAB, p 0.737). Survival was comparable when analyzing subgroups with diabetes mellitus, left ventricular dysfunction or chronic kidney disease, among others.ConclusionsIn our series, OPBAB has a comparable 10-year survival with CABG with CPB.
