Micra leadless pacemaker retrieval in a pediatric patient

Area of Science:

• Cardiology
• Medical Devices

Background:

• Leadless pacemakers offer a less invasive option for heart rhythm management.
• Post-operative heart block can occur following cardiac procedures.

Observation:

• A pediatric patient developed transient heart block requiring pacemaker implantation.
• A post-anesthesia gagging episode led to leadless pacemaker microdislodgement.

Findings:

• The dislodged pacemaker exhibited increased and intolerable capture thresholds.
• Successful device retrieval and reimplantation resulted in adequate thresholds and projected longevity.

Implications:

• This case highlights potential complications of leadless pacemaker placement, including dislodgement due to external stimuli.
• Careful patient monitoring post-procedure is crucial for early detection of adverse events.
• Successful management underscores the feasibility of leadless pacemaker revision in pediatric cases.
