Off-Pump vs. On-Pump CABG : Up-Date

Abstract

Off-pump coronary artery bypass grating (OPCAB) is a standard procedure in Japan. This widespread use of OPCAB in Japan is supported by a number of studies that have been performed in the Japanese population, although most of these studies are retrospective singleinstitutions. Several clinical trials have been conducted worldwide and have demonstrated no benefit of OPCAB over traditional CABG with respect to these outcomes. Ultimately, OPCAB is associated with less effective myocardial revascularization and does not entirely prevent complications traditionally associated with cardiopulmonary bypass. Even so, OPCAB may improve operative outcomes by reducing the rates of perioperative myocardial injury, stroke, neurocognitive impairment, and cardiac-related mortality for elderly high-risk patients with co-morbidities. We will continue to polish this effective procedure in an aging society.
