 Doppler assessment of left ventricular diastolic function (LVDD)

Mitral inflowPulmonary venous inflowTDI MAM
At least two Doppler criteria consistent with moderate to severe left ventricular diastolic function were required to distinguish from normal diastolic function.
A, peak mitral filling velocity at atrial contraction; D, peak velocity of pulmonary venous forward flow during diastole; DT, deceleration time of mitral E wave; E, peak early mitral inflow filling velocity; e′, peak velocity of lateral mitral annulus motion during early diastole; MV Adur, duration of mitral A wave; PV Adur, duration of pulmonary venous reversal wave at atrial contraction; S, peak velocity of pulmonary venous forward flow during systole; TDI MAM, tissue Doppler imaging of mitral annular motion.
