Overview

MSCT may support noninvasive graft assessment after CABG; leaves open prospective validation of accuracy versus angiography.

Structured PICO

Does MSCT accurately assess bypass graft patency compared to angiography in patients undergoing CABG with T-grafts?

P
Population
26 patients who underwent elective coronary surgery utilizing a T-Graft (free right internal thoracic or radial artery centrally implanted into the left internal thoracic artery)
I
Intervention
Multi-slice computed tomography (MSCT) including volume rendering on postoperative day 8
C
Comparator
Arterial coronary angiography on postoperative day 8
O
Outcome
Bypass graft patency rate and patency rate of anastomosessurrogate

MSCT is a reliable, less invasive alternative to angiography for assessing bypass graft patency after complex CABG, though it has limited ability to quantify stenosis.

Limitations

  • The ability to quantify stenosis is restricted.
