Bioprostheses are prone to structural valve degeneration, resulting in limited long-term
durability. A significant challenge when comparing the durability of different types of …

After 15 years of successive randomized, controlled trials, indications for transcatheter aortic
valve replacement (TAVR) are rapidly expanding. In the coming years, this procedure could …

Bioprosthetic valve dysfunction (BVD) and bioprosthetic valve failure (BVF) may be caused
by structural or nonstructural valve dysfunction. Both surgical and transcatheter bioprosthetic …

Aims There are limited data on coronary obstruction following transcatheter valve-in-valve
(ViV) implantation inside failed aortic bioprostheses. The objectives of this study were to …

Background: Mitral valve-in-valve (ViV) and valve-in-ring (ViR) are alternatives to surgical
reoperation in patients with recurrent mitral valve failure after previous surgical valve repair …

Aims Due to bioprosthetic valve degeneration, aortic valve-in-valve (ViV) procedures are
increasingly performed. There are no data on long-term outcomes after aortic ViV. Our aim …

Background The majority of transcatheter aortic valve implantation (TAVI) procedures are
currently performed by percutaneous transfemoral approach. The potential contribution of …

Objectives The aim of this study was to evaluate early results of valve-in-valve (ViV)
transcatheter aortic valve replacement (TAVR) versus redo surgical aortic valve replacement …

Background—Transcatheter valve implantation inside failed bioprosthetic surgical valves
(valve-in-valve [ViV]) may offer an advantage over reoperation. Supra-annular transcatheter …

Objectives: The aim of this study was to determine whether the association of small label
size of the surgical valve with increased mortality after transcatheter valve-in-valve (ViV) …
