The aim – to study the features of longitudinal segmental displacement of left ventriclar walls in patients with mitral insufficiency.
Material and methods. Echocardiography has been used to diagnose mitral insufficiency, as well as to determine its severity, intensity of dilatation and evaluation of functional condition of myocardium. It included M- and B-mode echocardiography, continuous and impulse Doppler, color Doppler mapping. Special attention has been given to novel technology of speckle-tracking, based on two-dimensional echocardiography. 54 patients with mitral insufficiency have been involved into the study. 35 patients with normal heart have been assigned to the control group.
Results. Left ventricular volumes were significantly higher in group of patients with mitral insufficiency; at the same time the ejection fraction was normal. The degree of mitral insufficiency reached severe grade, whereas pulmonary hypertension was moderate. No apparent signs of heart failure and coronary arteries involvement were noted. Displacement of basal, middle and apical parts of all walls didn’t differ from the control group. However, the tendency to increase in longitudinal displacement of basal segments in the inferoseptal, posterior, anterior and inferior walls has been noted.
Conclusions. In mitral insufficiency the indices of displacement of basal, middle and apical portions of left ventricular walls were not changed. However, displacement of basal segments of the inferoseptal, posterior, anterior and inferior walls were tending to increase, compared to normal heart.
