Summary
Device migration is a rare complication of implantable loop recorder (ILR) implantation. This case highlights the first instance of subpleural penetration by a new-generation ILR, emphasizing the need for careful implantation techniques and monitoring.
Area of Science:
- Cardiology
- Medical Devices
- Surgical Complications
Background:
- Implantable loop recorders (ILRs) are crucial for diagnosing conditions like syncope and cryptogenic stroke.
- ILR implantation is generally safe, but rare complications such as device migration can occur.
Observation:
- A 65-year-old woman experienced loss of remote communication with a new-generation Biotronik ILR-BioMonitor 3 one week after implantation.
- Imaging revealed the ILR had migrated into the left pleural cavity.
Findings:
- This is the first reported case of subpleural penetration by the new Biotronik ILR-BioMonitor 3.
- The device's small size and sharp antenna may contribute to migration risk.
Implications:
- Subcutaneous implantation should utilize a minimal penetration angle, parallel to the sternum.
- Close post-implantation follow-up is recommended to detect early signs of device migration.
