Valve Performance of the SAPIEN 3 Ultra RESILIA Valve: A Prospective Registry With Central Echocardiography Analysis.

Inclusion Criteria: * Inclusion criteria - Patients with severe aortic stenosis undergoing transarterial TAVR with the SAPIEN 3 Ultra RESILIA valve. * Successful valve implantation of the SAPIEN 3 Ultra RESILIA valve. VARC-3- defined technical success defined as: * Freedom from mortality * Successful access, delivery of the device, and retrieval of the delivery system * Correct positioning of a single prosthetic heart valve into the proper anatomical location * Freedom from surgery or intervention related to the device (excluding permanent pacemaker) or to a major vascular or access related, or cardiac structural complication - Absence of severe procedural or in-hospital complications (VARC-3 definitions): mortality, stroke, bleeding type 2-4, myocardial infarction, need for a second valve, valve embolization, coronary obstruction, annular rupture. Exclusion Criteria: * Age \>80 years * Severe pulmonary disease (FEV1 \<50% predicted or need for home oxygen) * Severe renal dysfunction (eGFR \<30 ml/min/1.73m2) * Frailty (Clinical Frailty Scale \> 4) * Severe coronary disease (SYNTAX score \>32) * Left ventricular ejection fraction ≤30% * Moderate-to-severe mitral regurgitation * Severe tricuspid regurgitation * Pulmonary systolic pressure \>60 mmHg * STS-PROM \>5% * Any disease leading to a life expectancy \<5 years
