Comparison of Doppler Flow Velocity and Thermodilution Derived Indexes of Coronary Physiology.

ABSTRACT:

Objectives

The aim of this study was to compare Doppler flow velocity and thermodilution-derived indexes and to determine the optimal thermodilution-based diagnostic thresholds for coronary flow reserve (CFR).

Background

The majority of clinical data and diagnostic thresholds for flow-based indexes are derived from Doppler measurements, and correspondence with thermodilution-derived indices remain unclear.

Methods

An international multicenter registry was conducted among patients who had coronary flow measurements using both Doppler and thermodilution techniques in the same vessel and during the same procedure.

Results

Physiological data from 250 vessels (in 149 patients) were included in the study. A modest correlation was found between thermodilution-derived
