Short summary
Deeper implantation in small valve-in-valve transcatheter aortic valve replacement (ViV TAVR) may worsen hemodynamic outcomes and mechanical consequences.

Key points
- Valve-in-valve (ViV) TAVR in small surgical bioprostheses often results in high gradients and prosthesis-patient mismatch.
- Implantation depth is an operator-controlled variable in ViV TAVR.
- Guidance on optimal implantation depth for various valve combinations is currently limited.
- The study explores the relationship between implantation depth and hemodynamic/mechanical outcomes.

Abstract
Valve-in-valve (ViV) transcatheter aortic valve replacement in small surgical bioprostheses is often limited by residual gradients and prosthesis-patient mismatch. Implantation depth is operator-controlled, but depth guidance for different valve combinations remains limited.
