Intravascular Imaging-Derived Physiology-Basic Principles and Clinical Application

Cardiol Clin. 2024 Feb;42(1):89-100. doi: 10.1016/j.ccl.2023.07.005.

Abstract

Intravascular imaging-derived physiology is emerging as a promising tool allowing simultaneous anatomic and functional lesion assessment. Recently, several optical coherence tomography-based and intravascular ultrasound-based fractional flow reserve (FFR) indices have been developed that compute FFR through computational fluid dynamics, fluid dynamics equations, or machine-learning methods. This review aims to provide an overview of the currently available intravascular imaging-based physiologic indices, their diagnostic performance, and clinical application.

Keywords: Functional lesion assessment; IVUS-based FFR; OCT-based FFR; OFR; Percutaneous coronary intervention; Virtual FFR.
