Summary
A novel loop wire technique successfully retrieved a wedged Aveir leadless pacemaker (LP) by releasing its docking button in the right ventricle (RV). This method offers a solution for difficult pacemaker retrievals.
Area of Science:
- Cardiology
- Medical Devices
- Interventional Procedures
Background:
- The Aveir leadless pacemaker (LP) is designed for minimally invasive cardiac rhythm management.
- Occasionally, the LP's docking button can become difficult to access due to its position within the right ventricle (RV).
Observation:
- A specific case presented a challenge where the Aveir LP's docking button was wedged in the inferior wall of the RV.
- Standard retrieval methods may be hindered by such anatomical positioning.
Findings:
- A loop wire technique was employed to successfully release the wedged docking button.
- This maneuver allowed for the effective retrieval of the Aveir LP.
Implications:
- The loop wire technique provides a potential solution for challenging Aveir LP retrievals.
- This method may improve procedural success rates when the pacemaker is lodged in difficult-to-access locations within the RV.
