# A Rare Cause of Severe Bioprosthetic Transvalvular Regurgitation Diagnosed by Transesophageal Echocardiogram

## TL;DR

A rare cause of heart valve leakage after surgery was identified using advanced imaging techniques.

## Contribution

The study highlights suture snare of a strut as a rare but significant cause of valve dysfunction.

## Key findings

- Suture snare of a strut can lead to severe transvalvular mitral regurgitation after bioprosthetic mitral valve replacement.
- Intraoperative transesophageal echocardiography is crucial for assessing hemodynamic issues during valve surgery.
- Three-dimensional imaging enhances the detection of bioprosthetic valve dysfunction after surgery.

## Abstract

•Suture snare of a strut may cause severe transvalvular MR after bioprosthetic MVR.•Intraoperative TEE is vital in evaluating hemodynamic instability in MVR surgery.•3D imaging improves the diagnosis of bioprosthetic dysfunction post-MVR.

Suture snare of a strut may cause severe transvalvular MR after bioprosthetic MVR.

Intraoperative TEE is vital in evaluating hemodynamic instability in MVR surgery.

3D imaging improves the diagnosis of bioprosthetic dysfunction post-MVR.
