ValveinvalveTechniken
ValveinvalveTechniken refers to transcatheter procedures in which a transcatheter heart valve is implanted within a previously implanted bioprosthetic valve that has degenerated. The goal is to restore valve function while avoiding redo surgery through sternotomy. By treating stenosis, regurgitation, or mixed dysfunction, ViV techniques aim to reduce symptoms and improve hemodynamics in patients at higher surgical risk.
Indications include symptomatic dysfunction of a degenerated bioprosthetic valve after prior surgery, particularly in patients with
Planning relies on multimodality imaging, especially CT, to determine the inner diameter of the failed valve,
In some situations, the bioprosthetic valve fracture technique may be employed to fracture the surgical frame
Early and mid-term outcomes from experienced centers show meaningful symptom relief and favorable survival in appropriately
