Parameters of left ventricular deformation in elderly and senile patients with aortic stenosis after transcatheter implantation of the aortic valve

Abstract

Aim: To evaluate the parameters of left ventricle (LV) myocardial deformation (longitudinal, circular and radial) in patients with symptomatic severe aortic stenosis (AS) with preserved LV ejection fraction after transcatheter aortic implantation valve (TAVI) in the early postoperative period.Material and Methods. The study included 31 patients after TAVI out of 69 with symptomatic severe AS. Echocardiography (EchoCG) using two-dimensional speckle tracking technology was performed before TAVI and in the early postoperative period (within 5 ± 1,7 days).Results. There were no significant differences in the analysis of deformation parameters before TAVI and in the early postoperative period. There was a tendency to increase the longitudinal deformation of the LV, including the longitudinal deformation of the basal, middle and apical segments in individual patients. The longitudinal deformation of the left atrium did not change after TAVI.Conclusion. There were no significant changes in deformation parameters in elderly and senile patients with severe AS and preserved LV ejection fraction and with reduced LV deformation (longitudinal, circular and radial) after minimally invasive TAVI in the early postoperative period. There is a tendency to increase the global longitudinal deformation of the LV.
