Cine computed tomographic evaluation of aortocoronary bypass graft patency.
Evaluation of the patency of coronary bypass grafts has previously required hospitalization for invasive angiography. This report of three cases documents the unique capability of cardiac cine computed tomography to easily and accurately define coronary bypass graft patency. In each case, the findings altered therapeutic decisions. This early experience justifies wider application of this techn...
متن کاملAortocoronary bypass graft patency assessed by coronary computed tomography angiography--unicentric study.
UNLABELLED Coronary artery bypass graft (CABG) surgery is used to revascularize ischemic myocaydium affected by coronary artery obstruction. Conventional coronary angiography (CCA) is an invasive method used for graft evaluation. Nowadays, in post CABG patients grafts can be assessed noninvasively by using coronary computed tomography angiography (CCTA). AIM To determine the late patency rate...
متن کاملValue and limitations of computed tomography in assessing aortocoronary bypass graft patency.
To determine the value of nondynamic computed tomography (CT) in assessing aortocoronary bypass graft patency, we studied 67 patients with 125 grafts by CT and by coronary angiography at close time intervals. CT scans were performed before and after one to three (average 1.98 +/- 0.65) 50-ml i.v. bolus injections of contrast material. Eighty-four of 92 grafts patent at angiography were also vis...
متن کاملImaging and evaluation of coronary artery bypass graft patency by 16-slice multidetector computed tomography.
INTRODUCTION The purpose of this study was to evaluate the patency of coronary artery bypass grafts (CABGs) while assessing the capabilities and limitations of 16-slice multidetector computed tomography. METHODS We studied retrospectively 19 patients (13 men, 6 women), over an 18-month period. All patients had undergone CABG surgery 3 months to 7 years earlier. Two patients were examined on a...
