Abstract

The primary goal of coronary surgery is the delivery of increased blood flow to regions of myocardium previously underperfused. Postoperative evaluation of coronary bypass grafts is generally performed by selective graft arteriography, which provides anatomic detail but provides little information regarding graft flow or regional distribution. Several methods have been used to evaluate bypass flow using hydrogen and xenon-133 washout1,2 or videodensitometry.3 None of these techniques provides information regarding the myocardial distribution of graft flow.
