Does vector flow mapping (VFM) accurately quantify diastolic energy loss to determine the severity of aortic regurgitation?
Vector flow mapping can quantify diastolic energy loss, which increases proportionally with aortic regurgitation severity, offering a new measure of cardiac load.
VFM provides a promising method to quantify diastolic EL in AR. Diastolic EL increases in AR proportional to its severity. EL may be useful to determine the severity of disease from the aspect of cardiac load.
Stugaard et al. (Mon,) studied this question.
