title: Outcomes of off-pump coronary artery bypass surgery: current best available evidence.
abstract: In the last decade, there has been an upsurge of interest in less invasive alternatives to standard coronary artery bypass grafting performed with cardiopulmonary bypass. Off-pump coronary artery bypass grafting is one such less invasive alternative that has seen a resurgence in the last 10 years. The development and application of the technology required has largely been driven by the hope of decreasing the incidence and/or severity of the adverse outcomes associated with cardiopulmonary bypass, the idea being to perform coronary artery bypass grafting without cardiopulmonary bypass. A number of studies that have reported the safety and efficacy of off-pump coronary artery bypass surgery have provided the impetus for the development of this technology over the last decade. Despite tremendous enthusiasm on the part of cardiac surgeons, patients, industry and the media, skepticism still exists about the actual impact of off-pump coronary artery bypass grafting on the outcomes after coronary artery bypass grafting. The only means of countering this skepticism is to validate the safety and efficacy of off-pump coronary artery bypass surgery through the explicit and conscientious assessment of current best evidence. This review article attempts to evaluate the current best evidence available from randomized, controlled trials in order to compare the outcomes of off-pump coronary artery bypass surgery and conventional coronary artery bypass grafting.
