Plaque volume derived from three-dimensional reconstruction of coronary angiography predicts the fractional flow reserve.

Objectives: To compare the data calculated from the three dimensional (3D) reconstruction of a coronary stenosis with the fractional flow reserve (FFR) values measured on the same coronary segment.

Methods: Multiple projections of 22 patients (7 female, 15 male, age: 61 ± 9.73 years) were evaluated by the IC30 software of the Axiom Artis X-ray machine.
