# A Rare but Severe Long‐Term Complication of an Implantable Chamber

## TL;DR

A long-term implantable device can cause serious heart complications years later if not properly checked before reuse.

## Contribution

Highlights a rare but severe complication of implantable ports and emphasizes the need for careful pre-use verification.

## Key findings

- Delayed mechanical erosion from a dormant device can lead to pericardial effusion.
- Reusing an implantable port without verifying catheter integrity can cause life-threatening cardiac tamponade.

## Abstract

Long‐term implantable ports may cause severe complications even years after placement. This case highlights the importance of verifying catheter integrity and tip position before reusing a dormant central venous access device, as delayed mechanical erosion can lead to pericardial effusion and life‐threatening cardiac tamponade.
