Severe MR suggested
- Closure drift of the AV at the end systole in the presence of normal LVEF.
- ↑ LA/LV diameter; Flailed MV leaflet; papillary muscle rupture.
- CW: ↑↑ signal intensity/density and presence of “v” wave cut off sign.
- MV VTI/LVOT VTI ≥ 1.3.
- MR Color flow area averaged/LA Area averaged in 3 planes (mild <20%, moderate 20–40%, severe >40% mosaic part of a jet only).
- Color eccentric MR jet reaching posterior wall of LA and entering into RUPV and LUPV.
- Increased E velocity (≥1.4 m/sec native, >2.0 m/sec prosthetic) without increase of DT (deceleration time).
Severe MR most likely ruled out
- Presence of significant spontaneous contrast in LA.
- A > E in mitral inflow pattern.
