| Popis: | Background: The NOTION trial (Nordic Aortic Valve Intervention) was designed to compare transcatheter aortic valve replacement (TAVR) with surgical aortic valve replacement (SAVR) in patients ≥70 years old with isolated severe aortic valve stenosis. Clinical and echocardiographic outcomes are presented after 5 years. Methods: Patients were enrolled at 3 Nordic centers and randomized 1:1 to TAVR using the self-expanding CoreValve prosthesis (n=145) or SAVR using any stented bioprostheses (n=135). The primary composite outcome was the rate of all-cause mortality, stroke, or myocardial infarction at 1 year defined according to Valve Academic Research Consortium-2 criteria. Results: Baseline characteristics were similar. The mean age was 79.1±4.8 years and mean Society of Thoracic Surgeons Predicted Risk of Mortality score was 3.0%±1.7%. After 5 years, there were no differences between TAVR and SAVR in the composite outcome (Kaplan-Meier estimates 38.0% versus 36.3%, log-rank test P =0.86) or any of its components. TAVR patients had larger prosthetic valve area (1.7 cm 2 versus 1.2 cm 2 , P P P P Conclusions: These are currently the longest follow-up data comparing TAVR and SAVR in lower risk patients, demonstrating no statistical difference for major clinical outcomes 5 years after TAVR with a self-expanding prosthesis compared to SAVR. Higher rates of prosthetic regurgitation and pacemaker implantation were seen after TAVR. Clinical Trial Registration: URL: https://clinicaltrials.gov . Unique identifier: NCT01057173. |
