Key result
Valve-in-valve TAVI in stentless bioprostheses can migrate over 2 years after implantation.
Why the study?
Late migration of a valve-in-valve TAVI prosthesis is extraordinarily rare and not well documented.

May warrant prolonged surveillance after ViV TAVI; leaves open incidence and mechanisms in stentless valves.
Case Report (n=1)
This case highlights the rare but possible complication of very late migration (>2 years) of a valve-in-valve TAVI prosthesis deployed in a stentless bioprosthetic aortic valve.
Burmeister et al. (2025) conducted a case report in Failed bioprosthetic surgical aortic valve replacement (n=1). Valve-in-valve (ViV) TAVI was evaluated on Late migration of prosthesis. Very late migration of a valve-in-valve TAVI prosthesis can occur >2 years after implantation into a stentless bioprosthetic aortic valve.
