Purpose - Bypass grafting is the gold standard for severe coronary disease, yet most repeat revascularizations target previously grafted territories. External stenting of saphenous vein grafts, the most frequently used bypass conduit, has been shown to minimize disease markers. This study evaluates clinical outcomes of external stenting in real world routine practice.

Methods - Three centers enrolled a prospective real-world cohort of external- stenting- enhanced CABG patients. All patients received an internal mammary artery graft to the left anterior descending artery and additional arterial and/or venous grafts. One or more venous grafts were externally stented. Choice of conduits, use of cardiopulmonary bypass, and vein harvesting technique were performed according to the routine practice of each surgeon.

All patients were prescribed standard of care medication and were followed via on site visits or phone interviews for major adverse myocardial and cerebral effects.
