Patterns of phasic coronary collateral flow velocity in patients.
Antegrade or retrograde collateral flow velocity Doppler signals, acquired with the flowire, permit the quantitation of collateral blood flow and its phasic patterns. The velocity spectra are easily visualized, and reproducible alterations during balloon occlusion may be directly related to coronary collateral flow-dependent variables of ischemia and left ventricular wall motion. The effects of pharmacologic stimulation on collateral flow remain under study.
