Methods Mitral annular motion in 35 cases of normal subjects form apicial four chamber view and two chamber view were detected with DTI M mode.

Discrimination of Pseudonormalized Echocardiographic Doppler Transmitral Filling Velocity Profile by Mitral annular slope;

Mitral annulus in patients with myocardial infarction evaluated by real-time three-dimensional echocardiography;

Objective To probe the value of mitral annulus peak systolic flow velocity and systolic displacement in evaluating left ventricular systolic function of dilated cardiomyopathy patients.

Methods Mitral annulus velocities from posteroseptal,lateral,anteroseptal,posterior,anterior and inferior segments during early diastole (Ve),atrial contraction (Va) were measured by quantative tissue velocity imaging in 14 patients with dilated cardiomyopathy and in 14 age matched healthy subjects,and then Ve/Va was calculated.
