Why the study?
Does magnetic resonance imaging (MRI) accurately assess graft patency or occlusion in patients with coronary artery bypass grafts?

MRI is a highly accurate, non-invasive technique for assessing coronary artery bypass graft patency, which could be useful for patients presenting with post-operative angina.

Supports MRI for non-invasive CABG graft assessment in symptomatic patients; leaves open prospective validation before changing practice.
In a study of 22 patients with 60 coronary artery bypass grafts, magnetic resonance imaging (MRI) correctly assessed graft patency or occlusion in 90% of cases when compared with selective coronary graft angiography and computed tomography. It is concluded that MRI can detect a normally functioning coronary artery bypass graft and could be used as a non-invasive technique to assess graft patency in patients presenting with post-operative angina.
