## TL;DR

A new technique uses a single snare catheter to reposition a stuck Micra device in the tricuspid valve for successful retrieval.

## Contribution

A novel bailout technique using a single snare catheter to reposition and recapture a fixed Micra device.

## Key findings

- Using a single snare catheter from the superior vena cava can reposition a fixed Micra device.
- Pushing the tines changes the device orientation, enabling successful recapture.

## Abstract

When we recapture the Micra system, we capture the body by pulling the tether attached to the delivery catheter and retrieve it, but sometimes it is difficult, and the Micra is dislodged and fixed in the tricuspid valve annulus. Using a single snare catheter from the superior vena cava and pushing the tines changes the orientation of the device and enables recapture.
