Does the upstream sampling dye-dilution technique accurately quantitate aortic regurgitation compared to an electromagnetic flowmeter in a canine model?
The upstream sampling dye-dilution technique provides a valid estimation of aortic regurgitation severity, particularly for small-to-moderate regurgitation, correlating well with electromagnetic flowmeter measurements in a canine model.
