Comparing two methods for using saphenous vein in heart bypass surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial evaluates the effectiveness of two different grafting techniques for coronary artery bypass grafting (CABG) using the saphenous vein. Patients will be randomized to receive either a Y-composite graft with the left internal thoracic artery or an aortocoronary conduit. The study aims to assess the morphologic changes of the saphenous vein graft and its patency at one year through intravascular ultrasound and angiography. The trial will involve routine sternotomy and follow-up evaluations to determine clinical outcomes.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* A patient who is going to receive coronary artery bypass grafting
* Older than 19 years
* Coronary artery bypass grafting is going to be performed with left internal thoracic artery and saphenous vein graft

Exclusion Criteria:

* Other concomitant procedures (e.g. valve or aorta surgery) is planned
* Patients with severe comorbidities which limit the life expectancy of them below 1 year (e.g. terminal cancer)
* Patients whose left internal thoracic artery or saphenous vein is not available due to the low quality, severe injury, or absence of the graft
* Patients whose ascending aorta is not suitable to aortocoronary anastomosis (e.g. ascending aorta aneurysm, porcelain aorta)
* Emergency operation
* Patients who have connective tissue disease
* Reoperative coronary artery bypass grafting
