Randomization of Single vs Multiple Arterial Grafts

Condition(s) studied

Investigational drug(s) / intervention(s)

Single arterial graft: This interventions consists of patients receiving the left internal thoracic artery to the left anterior descending coronary artery of the heart. In addition to the left internal thoracic artery patients will receive venous grafts for all additional grafting.

Multiple arterial grafting: This intervention consists of the patient receiving the left internal thoracic artery to the left anterior descending coronary artery of the heart. The second arterial graft (right internal thoracic artery or radial artery) will be directed to the major branch of the circumflex. Additional grafts will include saphenous veins or arterial conduits.

Study summary

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.

Eligibility

Primary outcome measure(s)

• Composite Outcome — > 72 hours after surgery and/or repeat revascularization
  A composite of death from any cause, any stroke, post discharge myocardial infarction and/or repeat revascularization.
