A Randomized Comparison of Off-Pump and On-Pump Multivessel Coronary-Artery Bypass Surgery

Abstract

In this randomized study, off-pump coronary surgery was as safe as on-pump surgery and caused less myocardial damage. However, the graft-patency rate was lower at three months in the off-pump group than in the on-pump group, and this difference has implications with respect to the long-term outcome.
