| Popis: | Aortic stenosis (AS) results in several left ventricular (LV) disturbances as well as progressive left atrial (LA) enlargement and dysfunction. Transcatheter aortic valve implantation (TAVI) reverses LV remodelling and improves overall systolic function but its effect on LA function remains undetermined. The aim of this prospective, longitudinal study was to investigate the effects of TAVI on LA structure and function. We studied thirty-two patients with severe symptomatic AS who underwent TAVI, using standard and 2-dimensional speckle-tracking echocardiography before, at 40-day and at 3-month follow-up. Following TAVI, mean transvalvular gradient decreased (p |
