Why the study?
Does a Doppler guide wire accurately measure coronary artery flow velocity compared to an electromagnetic flowmeter in model tubes and dog coronary arteries?
Does a Doppler guide wire accurately measure coronary artery flow velocity compared to an electromagnetic flowmeter in model tubes and dog coronary arteries?
The Doppler guide wire accurately measures phasic flow velocity patterns and linearly tracks changes in flow rate in small, straight coronary arteries, validating its potential use during coronary angiography and angioplasty.
No takes yet. Share an insight, caveat, or question.
Animal validation supports Doppler wire flow linearity; leaves open human coronary angiography translation.
Doucette et al. (1992) studied this question.
