Recurrence of angina pectoris in thesepatients is a common problem, and early graft occlusion isdescribed in up to 23% of all patients,1 with a large numberof patients developing angina pectoris within the initialthree months. Surgical revascularization is done usuallywith either arterial or venous grafts or the combinationof both. Arterial grafts (left or right internal mammarianartery or free arterial grafts) are preferable as they havea higher graft patency rate than venous grafts in short-and mid-time follow-up.2 Five years after coronaryartery bypass surgery approximately 90% of arterialgrafts are patent, in contrast to 80% of venous grafts. Thegold standard for direct visualization of coronary artery ves-sels is invasive X-ray coronary angiography. However, dueto its invasive character and possible complications, there isa need for non-invasive tools to assess coronary artery bypassvessels.Read More
