Radial vs. Vein Grafts for Heart Bypass Surgery
Part of Heart & circulation clinical trials.
This study compares two types of blood vessels used in heart bypass surgery: the radial artery (from your forearm) versus a vein (typically from your leg). Researchers want to see which graft option works better and lasts longer in women with severe heart disease.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are female, age 18 or older
- You have severe blockages in three heart arteries, including the circumflex artery (≥70% narrowed, at least 1.5 mm wide)
- You have chest pain or evidence of heart strain on stress tests that your doctor believes needs bypass surgery
- You have never had heart surgery before, including previous bypass surgery (CABG)
- Your heart pumps at least 35% of blood with each beat (normal ejection fraction)
- You do not have severe kidney disease (CKD stage 4 or worse) and can have blood vessels safely harvested

This trial compares two types of grafts (the radial artery from the arm and a vein from the leg) used in women having heart bypass surgery for the first time. It aims to see which graft works better and stays open longer.
This trial compares two types of blood vessels used in coronary artery bypass surgery: one from the arm (radial artery) and one from the leg (saphenous vein). The goal is to see which one works better for patients with severe heart disease.
This study compares two ways of doing bypass surgery for blocked heart arteries: using only chest and arm arteries versus a mix of arteries and leg veins. The goal is to see which approach works better for long-term heart health.
This study tests whether a new way to prepare the arm artery used in heart bypass surgery can help keep it open and working well. It may improve the success of your surgery.
This study looks at whether using one artery graft or multiple artery grafts during heart bypass surgery works better for people with specific coronary artery disease. You may be randomized to one approach, and the trial team will follow outcomes after surgery.
This study compares outcomes of using one bypass graft versus multiple bypass grafts during coronary artery bypass surgery in women. It aims to see which approach leads to better recovery and heart outcomes for eligible patients.
