Summary
A dislodged leadless pacemaker (LP) in the pulmonary artery was successfully retrieved using the double-snare technique. This method offers a safe alternative when standard retrieval tools fail, enhancing patient safety in LP therapy.
Area of Science:
- Cardiology
- Medical Devices
- Interventional Cardiology
Background:
- Leadless pacemakers (LPs) offer advantages by reducing lead-related complications.
- Early dislodgement of LPs is a rare but serious adverse event requiring prompt management.
- Standard retrieval methods may be insufficient for dislodged LPs in complex anatomical locations.
