title: Usefulness of cardiac computed tomography in the diagnosis of prosthetic coronary artery graft with interposition procedure.
abstract: An 80-year-old Japanese man was admitted with orthopnea and pitting edema of both lower legs. We diagnosed congestive heart failure (CHF) on the basis of a chest X-ray and an echocardiogram. An electrocardiogram showed a heart rate of 120 beats/min with atrial fibrillation rhythm (Af). The patient developed aortic valve failure and destruction of the base of right coronary artery (RCA) due to infectious endocarditis at 71 years of age. The patient underwent aortic valve replacement and coronary artery bypass grafting with an interposed graft with polyester vascular graft to RCA. The patient recovered from CHF after the 6 days of treatment with diuretics and verapamil. We confirmed the patency of coronary arteries and bypass grafts using a 64-slice cardiac computed tomography scan (CT) and diagnosed CHF due to Af. Here we describe the estimation of the prosthetic coronary artery graft patency with the interposition procedure using 64-slice cardiac CT.
