Randomized data on radial artery versus vein grafts
Gaudino led a patient-level analysis of 1,036 participants from randomized trials. At median ten-year follow-up, radial-artery grafting was associated with fewer events in the composite of death, myocardial infarction or repeat revascularization than saphenous-vein grafting.
How to interpret this: Pooled trials from five countries, not his own surgical cohort. The comparison concerns one conduit choice and does not establish superiority of all multiple-arterial strategies or robotic access.
