Mitral velocity propagation
Mitral flow propagation velocity (Vp) has been proposed
as an indicator of LV relaxation and correlates with invasive time
constants of relaxation.44 Additionally, E/Vp ratio
has been shown to correlate with LA pressure,45 but
may not be accurate in patients with normal EF.40Further, transmitral E wave velocity is governed by the severity of
mitral obstruction, making this measurement unreliable in the setting of
MS.
