Normal TDI of Lateral Mitral Annulus
(S', E', A' velocities are measured in cm/sec)

Age-related change in Lateral Mitral Annulus TDI
(24 yr old on the left; 82 yr old on the right)

Lateral Mitral Annulus TDI
(Impaired Relaxation: E' velocity is lower than A' velocity)

Lateral Mitral Annulus TDI
(Restrictive Pattern: Both E' & A' velocities are reduced, E' velocity is higher than A' velocity though)

Mitral Inflow Doppler (Normal)
DT - DecelerationTime of E wave
Adur - A wave Duration

(S, D and Atrial reversal)
