Abstract

Objective: To assess intermediate coronary artery lesions by 2D and 3D Quantitative Coronary Angiography (QCA) and compare the results with standard fractional flow reserve (FFR).

Background: FFR is the standard for assessment of physiological significance of an intermediate coronary stenosis, but it expensive, sometimes it is unavailable, or limited use by contraindications to adenosine, QCA especially three-dimensional (3D-QCA) can be used as another method to help in assessment of the intermediate coronary lesions.

Patients and methods: Thirty two vessels in 30 patients with intermediate coronary lesions were scheduled for FFR, 2D and 3D QCA measurement and the results of QCA were c... view more»
