Key result
Isovolumic relaxation flow patterns were significantly associated with LV function (P<0.05), with a persistent large intraventricular vortex indicating increasingly depressed LV function.

p-value: p=<0.05
Vector flow mapping identifies distinct intraventricular isovolumic relaxation flow patterns that correlate with the severity of left ventricular dysfunction.
Zhang et al. (2016) conducted an observational in Left ventricular dysfunction (coronary artery disease and dilated cardiomyopathy) (n=131). Left ventricular dysfunction vs. Healthy controls was evaluated on Isovolumic relaxation flow (IRF) patterns and association with LV function parameters (p=<0.05). Isovolumic relaxation flow patterns were significantly associated with LV function (P<0.05), with a persistent large intraventricular vortex indicating increasingly depressed LV function.
