Off-Pump Coronary Artery Bypass in Patients With Left Ventricular Dysfunction: A Meta-Analysis

Off-pump CAB may be associated with lower incidence of early mortality in patients with impaired left ventricular function, although the method of handling the conversion-related mortality in each study is uncertain and may challenge these results. Incomplete revascularization provided by the OPCAB group occurred more often, although its impact was not reflected in the clinical outcomes but may explain why the early advantage in mortality was not continued to the late term.
