# Computer-Assisted Transcatheter Mitral Valve Implantation for Valve-in-Valve Procedures

## TL;DR

This paper introduces a new imaging tool to guide heart valve implantation procedures, improving accuracy and reducing risks.

## Contribution

The study presents the first intraoperative guidance tool for transcatheter mitral valve-in-valve procedures.

## Key findings

- A patient-specific augmented imaging system was developed for preoperative planning.
- The tool combines preoperative and intraoperative data for real-time guidance.
- The method was successfully tested in a single case study.

## Abstract

Transcatheter mitral valve-in-valve is an alternative to high-risk reoperation on
a failing bioprosthesis. It entails specific challenges such as left ventricular
outflow tract obstruction. We propose a patient-specific augmented imaging based
on preoperative planning to assist the procedure.

Valve-in-valve simulation was performed to represent the optimal level of
implantation and the neo-left ventricular outflow tract. These data were
combined with intraoperative images through a real-time 3D/2D registration tool.
All data were collected retrospectively on one case (pre and per-procedure
imaging). We present for the first time an intraoperative guidance tool in
transcatheter mitral valve-in-valve procedure.
