Relationship between Quantitative Optical Coherence Tomography Parameter and Pressure-derived Fractional Flow Reserve for Assessing the Functional Severity of Coronary Stenosis
نویسندگان
چکیده
Background: Optical coherence tomography (OCT) allows us to evaluate not only the qualitative coronary lesion morphology but also the quantitative anatomical severity of coronary stenosis. Fractional flow reserve (FFR) is an established index to evaluate the functional severity of a coronary stenosis. The aim of this study was to determine the OCT parameters for physiological severity of coronary stenosis.

OBJECTIVES The main objective of this study was to assess the blood flow rate and velocity in coronary artery stenosis using intracoronary frequency domain optical coherence tomography (FD-OCT). A correlation between fractional flow reserve (FFR) and FD-OCT derived blood flow velocity is also included in this study. METHODS & RESULTS A total of 20 coronary stenoses in 15 patients were assesse...

BACKGROUND Little is known regarding intravascular ultrasound (IVUS) criteria to determine the functional severity of coronary stenosis. Recently, fractional flow reserve (FFR) has emerged as a lesion-specific index of the functional severity of a coronary stenosis that is independent of systemic hemodynamic variability. The present study was undertaken to determine the IVUS parameters for the ...

BACKGROUND The management of patients with angiographically intermediate coronary lesions is a major clinical issue. Fractional flow reserve provides validated functional insights while optical coherence tomography provides high resolution anatomic imaging. Both techniques may be applied to guide management in case of angiographically intermediate coronary lesions. Moreover, these techniques ma...
متن کاملValidation With Positron Emission Tomography
Background Experimental studies have shown that fractional flow reserve (defined as the ratio of maximal achievable flow in a stenotic area to normal maximal achievable flow) can be calculated from coronary pressure measurements only. The objectives of this study were to validate fractional flow reserve calculation in humans and to compare this information with that derived from quantitative co...
