Abstract
Aim. To asses the left atrium (LA) mechanical function in patients with ischemic mitral regurgitation (IMR) using technologies of vector analysis of endocardium movement rate. Materials and methods. The study enclosed 82 patients aged 59 ± 7,6 including 49 men (59,7 %). The entry criteria: EchoCG criteria of degree I-III ischemic mitral regurgitation, coronary artery lesions while fulfilling selective angiography corresponding to surgical revascularization criteria, sinus rhythm and normosystolia (heart rate from 60 to 89 per minute) during investigation, superior EchoCG visualization of LA endocardium. We suggest that atrial changes in deformation and deformation rate can be associated with severity of regurgitation. Results. Left atrium mechanical function indices decline proportionally to IMR severity. Longitudinal deformation and LA deformation rate reflect link with IMR greater than conventional indices used for estimation of LA geometry. Conclusions. Left atrium mechanical function indices are associated with IMR and connected with mechanical remodeling of the left atrium.
