## TL;DR

A new mitral annuloplasty ring was developed and tested for use in transcatheter valve procedures.

## Contribution

A new semirigid mitral annuloplasty ring was designed and bench-tested for valve-in-ring procedures.

## Key findings

- Bench testing confirmed that transcatheter valves can be anchored inside the new ring.
- Balloon filling volumes were determined for different sizes of valve-ring pairs.
- Heart team collaboration is recommended to optimize long-term valve disease management.

## Abstract

•A new mitral annuloplasty ring was purpose-built for transcatheter valve-in-ring.•Bench testing confirmed anchoring of transcatheter valves inside the ring.•Balloon filling volumes are provided for several sizes of valve-ring pairs.•Surgeons should consider future intervention when selecting an annuloplasty device.•Heart team collaboration can optimize lifetime management of mitral valve disease.

A new mitral annuloplasty ring was purpose-built for transcatheter valve-in-ring.

Bench testing confirmed anchoring of transcatheter valves inside the ring.

Balloon filling volumes are provided for several sizes of valve-ring pairs.

Surgeons should consider future intervention when selecting an annuloplasty device.

Heart team collaboration can optimize lifetime management of mitral valve disease.
