Time-Varying Survival Benefit of Radial Artery Versus Vein Grafting: A Multiinstitutional Analysis

Despite substantial differences in radial artery use patterns during a 15-year period, our analysis in large propensity-matched radial artery and saphenous vein cohorts yielded remarkably similar, time-varying radial artery to saphenous vein survival benefit at both institutions. These converging findings based on two independent patient series extend currently available objective evidence in support of a radial artery survival advantage in CABG.
