Abstract

Purpose: Validation of ultrafast-CT and MR-angiography (MRA) in comparison with angiography for detection of early postsurgical arterial and Venous coronary artery bypass graft (CABG) patency. Methods: 21 patients with a total of 55 CABG (34 Venous and 21 arterial) were studied with angiography, ultrafast-CT (EBT), and MRA. Results: With EBT, patency of 43/45 angiographically patent CABG could be correctly assessed (sensitivity: 96%). With MRA 26 CABG (17 Venous and 9 arterial) were identified as patent (sensitivity: 67%). It was not possible to quantify proximal stenosis of three grafts (> 40%) and to evaluate the distalbypass anastomosis with both EBT and MRA. Conclusions: Ultrafast-CT is a promising minimal invasive screening method for the evaluation of venous and arterial CABG patency. The diagnostic significance of MRA is remarkably reduced.
