BACKGROUND: The durability of transcatheter aortic bioprosthetic valves is a crucial issue, but data are scarce, especially beyond 5 years of follow-up. We aimed to assess long-term (7 years) structural valve deterioration (SVD) and bioprosthetic valve failure of transcatheter aortic bioprosthetic valves.
METHODS AND RESULTS: Consecutive patients with at least 5-year follow-up available undergoing transcatheter aortic valve implantation from April 2002 to December 2011 in 5 French centers were included. Incidence of SVD and bioprosthetic valve failure were defined according to newly standardized criteria of the European Association of Percutaneous Cardiovascular Interventions/European Society of Cardiology/European Association for Cardio-Thoracic Surgery and reported as cumulative incidence function to account for the competing risk of death. One thousand four hundred three consecutive patients were included with a mean age of 82.6±7.5 years and with a mean logistic EuroSCORE (European System for Cardiac Operative Risk Evaluation) of 21.3±7.5%. A balloon-expandable valve was used in 83.7% of cases. Survival rates were 83.5% (95% CI, 81.4%-85.5%) and 18.6% (95% CI, 15.3%-21.8%) at 1 and 7 years, respectively. Median duration of follow-up was 3.9 years. Bioprosthetic valve failure occurred in 19 patients with a 7-year cumulative incidence of 1.9% (95% CI, 1.4%-2.4%). SVD occurred in 49 patients (moderate, n=32; severe, n=17) with a 7-year cumulative incidence of moderate and severe SVD of 7.0% (95% CI, 5.6%-8.4%) and 4.2% (95% CI, 2.9%-5.5%), respectively. Five patients had aortic valve reintervention (1.0%; 95% CI, 0.4%-1.6%) including 1 case of surgical aortic valve replacement and 4 redo-transcatheter aortic valve implantation. The incidences of SVD and bioprosthetic valve failure were not significantly different between balloon and self-expandable prostheses.
CONCLUSIONS: The long-term assessment of transcatheter aortic bioprosthetic valves durability is limited by the poor survival of our population beyond 5 years. Further studies are warranted, particularly in younger and lower-risk patients.
