Figure 3 Estimation of Left Ventricular Diastolic Pressure by Tissue Doppler Imaging

Estimation of left ventricular diastolic pressure by the ratio of transmitral E (A) and mitral septal annular velocity (B), E/Ea. The E/Ea ratio in this patient is 8, which is within normal limits. His Ea is also within normal limits. (C and D) A patient with elevated left ventricular diastolic pressure and E/Ea ratio of 40, which is significantly elevated. Note also that the Ea is severely reduced to only 3 cm/s. Both of these parameters were associated with poor prognosis.
