Analysis of Coronary CT Angiography to Identify Patients With Significant Coronary Artery Stenosis
NCT02791113 · Status: UNKNOWN · Type: OBSERVATIONAL · Enrollment: 50
Last updated 2016-06-15
Summary
The investigators propose to develop a computational framework involving a novel automatic image segmentation algorithm based on CTA images, an artery model reconstruction algorithm for stenosis detection, and quantification of severity of stenosis in terms of area stenosis.

- OTHER
-
Fractional Flow Reserve (FFR) Measurement
FFR is defined as the distal pressure to coronary lesion divided by the proximal coronary pressure. FFR is measured through a standard diagnostic catheter during coronary angiogram. FFR is used to guide whether to perform angioplasty or stenting or not in patients with coronary stenosis.
