Comparative Study Observational StudyA comparison of valve-in-valve transcatheter aortic valve replacement in failed stentless versus stented surgical bioprosthetic aortic valves.
The objectives of this study were to compare short- and intermediate-term clinical outcomes, procedural complications, TAVR prosthesis hemodynamics, and paravalvular leak (PVL) in stentless and stented groups. ⋯ ViV in the stentless bioprosthetic aortic valve has excellent procedural success and intermediate-term results. Our study shows promising data that may support the application of TAVR in stentless surgical aortic valve. However, further and larger studies need to further validate our single center's experience.
