## TL;DR

A rare case of pacemaker lead migration causing heart and lung complications is presented with detailed imaging.

## Contribution

The paper presents a unique case of subacute pacemaker lead migration with extracardiac extension and pneumothorax.

## Key findings

- Pacemaker lead migrated subacutely, perforating the heart and extending into lung tissue.
- The complication resulted in a left-sided pneumothorax.
- Imaging confirmed involvement of multiple cardiac and thoracic structures.

## Abstract

Cardiac perforation with extracardiac extension by a pacemaker lead is a rare but serious complication of pacemaker placement. We present a unique case with imaging of a patient who underwent pacemaker placement complicated by subacute migration of the pacemaker lead, resulting in perforation involving interventricular septum, right ventricular apex, pericardium, epicardial fat, pleura and left upper lobe parenchyma with left-sided pneumothorax.
