The 2011-2012 pilot European Society of Cardiology Sentinel Registry of Transcatheter Aortic Valve Implantation: 12-month clinical outcomes

Aims: Our aim was to assess one-year outcomes of patients enrolled in the pilot European Sentinel Registry of Transcatheter Aortic Valve Implantation (TAVI). Methods and results: One-year outcomes of 4,571 patients (81.4±7.2 years, 2,291 [50.1%] male) receiving TAVI with the SAPIEN XT (57.3%) or CoreValve prosthesis at 137 European centres were analysed using Kaplan-Meier and Cox proportional hazards regression techniques. At one year, 3,341 patients were alive, 821 had died, and 409 were lost to follow-up. Of 2,125 patients who underwent functional assessment, 1,916 (90%) were in New York Heart Association (NYHA) Class I/II at one year, with functional improvement from baseline noted in 1,682 patients (88%). One-year survival based on 4,564 patients was estimated at 79.1%. Independent baseline predictors of mortality were increasing age and logistic EuroSCORE, the presence of NYHA III/IV, chronic obstructive pulmonary disease, and atrial fibrillation. Female gender was associated with a 4% survival benefit at one year. Vascular access routes other than transfemoral were associated with poorer survival. Procedural failure and major periprocedural complications had an adverse impact on survival. Conclusions: Contemporary European experience attests to the effectiveness of routine TAVI in unselected elderly patients.
