# Snare technique is useful for leadless pacemaker implantation in a patient with severe right atrial dilatation

## TL;DR

A new snare technique helped successfully implant a leadless pacemaker in a patient with a severely enlarged right atrium.

## Contribution

The snare technique provides a novel solution for implanting leadless pacemakers in patients with challenging anatomical conditions.

## Key findings

- The conventional approach failed due to insufficient backup force in a dilated right atrium.
- The snare technique enabled stable delivery by transmitting force to the pacemaker tip.
- The method successfully created a gooseneck shape for implantation.

## Abstract

Leadless pacemaker implantation in a patient with severe right atrium dilation was unsuccessful using the conventional approach. The delivery system failed to gain sufficient backup force from the atrial wall and moved upward within the dilated atrium. To overcome this, the snare technique was employed. By securing the slightly distal portion of the top of the shaft curve, the pushing force was effectively transmitted to the tip of the system, creating a stable gooseneck shape for successful implantation.
