Figure 1.

Representative examples of lateral and septal mitral annular velocities measured using Doppler tissue imaging (DTI) and transmitral left ventricular (LV) filling velocities in patients with hypertrophic cardiomyopathy (HCM) and controls. Diastolic annular velocities showed two waves away from the apex during early diastole and atrial contraction. A, transmitral late left ventricular filling velocity; Aa, late diastolic velocity of mitral annulus; E, transmitral early left ventricular filling velocity; Ea, early diastolic velocity of mitral annulus.
