Impaired Left Atrial Strain At Discharge After Transcatheter Aortic Valve Replacement (TAVI) Is Associated With Reverse Remodelling Of The Left Ventricle But Not The Left Atrium

Abstract

Introduction: Transcatheter aortic valve implantation (TAVI) can improve left ventricular (LV) mechanics and has been shown to improve long term survival. Data on the prognostic value of left atrial (LA) strain following TAVI are scarce. LA strain - a surrogate of LV filling pressure - can aid the early detection of diastolic dysfunction and correlates with the extent of fibrosis in atrial remodelling. In this multimodality study, we aimed to evaluate the prognostic value of LA function measured before hospital discharge following TAVI and to further elucidate its association with LV and LA reverse remodelling.
