3-D heart imaging to guide bypass surgery
Part of Heart & circulation clinical trials.
This study tests whether using a 3-D printed model of your heart, made from a CT scan, helps doctors plan and perform bypass surgery more precisely. It may improve surgical outcomes for people needing this procedure.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are scheduled for coronary artery bypass graft (CABG) surgery, which may include valve repair or replacement.
- Your surgery plan includes using the left internal mammary artery (LIMA) to the left anterior descending (LAD) artery, plus at least one other graft.
- You are 18 years or older.
- You do not have permanent atrial fibrillation, severe kidney disease (eGFR below 30), or an allergy to CT contrast dye.
- You are not pregnant or breastfeeding.
- You do not need emergency (acute) bypass surgery.
- You can tolerate medications like nitroglycerin and beta blockers (with an LVEF of 40% or higher) for the CT scan.

This study tests a special technique for heart bypass surgery that avoids clamping the aorta. It may help people with hardened arteries in the aorta who need bypass surgery but are not good candidates for standard clamping.
This study tests whether having a CT scan of the heart before a standard heart catheterization is helpful for people who have had bypass surgery. It could reduce risks and improve planning.
This study tests a new way to connect a bypass graft during heart bypass surgery for people with blocked heart arteries. The goal is to see if the new graft can be safely placed and works well enough to improve outcomes compared with the standard approach.
This trial compares two imaging methods used before coronary artery bypass grafting (CABG) to check for blocked heart vessels. The goal is to see if a CT scan is as good as the standard angiogram and equally helpful for planning surgery.
This study looks at tiny structures inside heart muscle cells (especially “power stations” in the cells) in people with certain types of heart failure who are getting coronary bypass surgery. It may help researchers better understand what changes happen in the heart and how this could guide future care.
This study looks at whether a special CT heart scan (CT angiography) can show how well bypass grafts are working in people who had a CABG after an acute coronary syndrome. It compares people managed with two anti-platelet medicines versus one aspirin, aiming to understand how well grafts stay open and guide care.
