The primary hypothesis of ROMA is that in patients undergoing primary isolated non-emergent coronary artery bypass surgery (CABG), the use of two or more arterial grafts compared to a single arterial graft is associated with a reduction in the composite outcome of death from any cause, any stroke, post discharge myocardial infarction and/or repeat revascularization. The secondary hypothesis is that in patients undergoing primary isolated non-emergent CABG, the use of two or more arterial grafts compared to a single arterial graft is associated with improved survival.

Prospective event-driven unblinded randomized multicenter trial of at least 4,300 subjects enrolled in at least 25 international centers. Patients will be randomized to a single arterial graft (SAG) or multiple arterial grafts (MAG). Patients will be randomized in a 1:1 fashion between the two groups. Permuted block randomization with random blocks stratified by the center and the type of second arterial graft will be used to provide treatment distribution in equal proportion.
