Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients aged 18 to 80 years scheduled for their first planned CABG with at least two sequential saphenous vein grafts.

Probably not a fit

Patients requiring additional cardiac surgeries or those with severe vascular or systemic conditions may not benefit from this study.

What this trial studies

This clinical trial evaluates the effectiveness of two surgical methods, RIMA-SVG and Ao-SVG, in patients undergoing coronary artery bypass grafting (CABG). A total of 300 patients will be randomly assigned to either the RIMA-SVG group, where saphenous vein grafts are connected to the right internal mammary artery, or the Ao-SVG group, where grafts are connected to the ascending aorta. The primary outcome is the patency of the grafts after one year, while secondary outcomes include complications such as mortality and major adverse cardiovascular events. Patients will be monitored for 12 months post-surgery to assess their clinical outcomes and graft health.

Why it matters

Potential benefit: If successful, this study could lead to improved graft patency and reduced complications for patients undergoing coronary artery bypass grafting.

How similar studies have gone: Other studies have explored similar surgical techniques, but the specific comparison of RIMA-SVG and Ao-SVG in this context is relatively novel.
