Coronary angiography incompletely delineates the physiologic consequences of many epicardial stenoses. Intracoronary translesional flow velocity measurements using the Doppler flow wire during cardiac catheterization provide immediate data discriminating the physiologic significance of coronary stenoses. The validity and accuracy of the flow wire for analyzing lesion hemodynamic significance have been confirmed in multiple studies. Flow velocity analysis provides objective criteria for refining the selection of cases for revascularization, and prospective clinical data have confirmed the safety of deferring intervention on lesions with normal physiologic assessment. Translesional and distal coronary flow velocity dynamics during procedures also provide immediate data assessing the physiologic adequacy of intervention. Impaired postintervention distal coronary flow velocity and vasodilator reserve can predict subsequent clinical events, and comparisons of flow velocity indices prestenting and poststenting suggest that physiologically inadequate results of angioplasty may be improved by additional intervention. Flow velocity assessment may also have utility in profiling the adequacy of infarct artery reperfusion following acute myocardial infarction. Evidence has been accumulated to support use of Doppler flow velocity analysis as a clinically relevant technique for improving both diagnostic and therapeutic aspects of cardiovascular medicine.
