Abstract

Materials and methods. The study enrolled107 patients aged 56 ± 7,5 among which 96 men (89,7 %). The entry criteria: I-III degree of ischemic mitral regurgitation on echocardiography, angiography reveling coronary artery disease requiring surgical revascularization, sinus rhythm with the heart rate ranging from 60 to 89 per minute, superior echocardiography visualization of LA endocardium. We hypothesize that atrial changes in deformation and deformation rate can be associated with severity of regurgitation..

Results. Values of left atrium mechanical function decline proportionally to IMR severity. Longitudinal deformation and LA deformation rate reflect link with IMR greater than conventional indices used for estima-tion of LA geometry.

Keywords

Ischemic mitral regurgitation, left atrium, longitudinal deformation
