Key result
Late diastolic vortex rings sit closer to the mitral annulus and are more elliptical than early rings.

Retrospectively-gated 4D Flow CMR is feasible for quantitatively characterizing 3D vortex rings in LV inflow, demonstrating distinct differences between early and late diastolic phases in normal subjects.
Elbaz et al. (2014) conducted an observational in Healthy (n=24). Early diastolic filling (E-vortex) vs. Late diastolic filling (A-vortex) was evaluated on Longitudinal position (L) of vortex ring core (p=0.0001). In normal subjects, late diastolic left ventricular vortex rings were significantly closer to the mitral valve annulus (L=0.15 vs 0.19) and more elliptical than early diastolic vortex rings.
