Background
Randomised trials show high long-term patency for no-touch saphenous
vein grafts in coronary artery bypass grafting. The patency rate in
off-pump coronary bypass surgery for these grafts has not been
investigated. Our centre participated in the CORONARY randomized trial,
NCT00463294. This is a study aimed to assess the patency of no-touch
saphenous veins in on- versus off-pump coronary bypass surgery at
five-year follow-up.
