Prognostic value of the atrial pulsed Doppler recordings of transmitral flow in the assessment of left ventricular diastolic dysfunction.

Volume sample location is the most important factor influencing pulsed Doppler recordings of left ventricular (LV) diastolic filling. Transmitral diastolic flow velocities measured at the tips of mitral valve leaflets are usually higher than those obtained from atrial location. Nevertheless, independently of volume sample location, differences between early to late velocities ratio (E/A) are nonsignificant, so E/A became the most useful index of ventricular diastolic performance.
