Brief summary
The present study hypothesizes that the systematic use of bilateral internal mammary artery (BIMA) grafting is feasible in the practice of a University Cardiac Surgery Institution for the treatment of multivessel coronary artery disease (primary hypothesis). The secondary study hypothesis is that the BIMA grafting meets the safety endpoint compared with the conventional surgical strategy entailing left mammary artery grafting plus great saphenous vein grafts to revascularize the remaining coronary targets. The tertiary study hypothesis is that the BIMA grafting yields better follow-up results in terms of recurrence of symptoms related to coronary disease, of repeat revascularization and of cardiac mortality compared with patients treated with the conventional surgical strategy entailing left mammary artery grafting plus great saphenous vein grafts to revascularize the remaining coronary targets.
Interventions
Both the left and the right internal mammary arteries are harvested and used to revascularize the two major coronary targets. Further coronary targets may be revascularized using either great saphenous vein or radial artery grafts, if present.
These patients had only the left mammary artery harvested and used to revascularize the major coronary target. Great saphenous vein grafts and/or radial artery grafts were employed to revascularize the remaining targets.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Feasibility of systematic BIMA grafting | 2012-2014 (2 years) | Starting in June 2012, all clinical data concerning patients undergoing BIMA grafting are recorded, including the baseline demographics and risk factors, the operative time, all in-hospital complications, duration of Intensive care Unit and Hospital stays, the amount of transfusion of blood products. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Clinical results at follow-up | 2012-2016 (4 years) | The patients enrolled in the study are subjected to longitudinal follow-up to determine the rate of residual myocardial ischemia (periodical stress ECG), of recurrent symptoms of coronary disease, and of any adverse cardiac event (periodical follow-up visits). |
