# A Case of Tricuspid Valve and Papillary Muscle Rupture Due to Entrapment of the Tendon of the Tricuspid Valve by the PENTARAYTM Catheter

## TL;DR

A case report highlights a tricuspid valve and papillary muscle rupture caused by a catheter during an ablation procedure.

## Contribution

The paper presents a novel clinical case emphasizing catheter handling techniques to prevent valve injury.

## Key findings

- Tricuspid valve rupture occurred due to entrapment by the PENTARAYTM catheter.
- Applying torque during catheter passage increases the risk of valve and muscle damage.
- Careful catheter navigation through the valve annulus is critical to avoid complications.

## Abstract

When using multipolar mapping catheters for catheter ablation, take care to pass through the central portion when crossing the valve annulus or chordae tendineae, and avoid applying torque as much as possible.
