A morphometric 3D model of coronary artery bypass graft dysfunction with multidetector computed tomography

Clin Imaging. 2015 Nov-Dec;39(6):1006-11. doi: 10.1016/j.clinimag.2015.07.011. Epub 2015 Jul 17.

Abstract

Objective: The objective was to assess, with computed tomography (CT) angiography, quantitative morphological parameters of a composite coronary artery bypass grafting (CABG) strategy and to correlate these with graft dysfunction.

Findings: Forty patients [median postoperative time, 32 (14-51) months] underwent CT angiography. Graft patency was assessed, and specific quantitative morphological parameters of the graft were collected. Graft segments had an overall patency rate of 93% (78/84). Two specific morphological parameters were found to be associated with graft dysfunction.

Conclusion: A CT morphometric model can be used to identify quantitative 3D parameters associated with graft dysfunction. Such an approach could help in developing and improving CABG designs.
