From: Assessment of left ventricle preload by transthoracic echocardiography: an easy task?
Example for estimating the left ventricle filling pressures from transmitral flow (a) and mitral annular velocities (septal in b and lateral in c), obtained in apical four-chamber view. The E velocity is 102 cm/s and the averaged annular velocity (septal and lateral/2) is 4.27 cm/s, with E/Ea ratio of 23.8, indicating a severe elevation of filling pressures
