Leadless pacemaker use in a patient with a durable left ventricular assist device

Area of Science:

• Cardiology
• Medical Devices
• Electrophysiology

Background:

• Left ventricular assist devices (LVADs) are crucial for end-stage heart failure.
• Pacemaker dependency is a common complication in LVAD patients.
• Transvenous pacemaker infections pose significant risks in this population.

Observation:

• A pacemaker-dependent patient with a durable LVAD presented with a transvenous pacemaker infection.
• Traditional pacemaker revision or replacement was deemed high-risk.

Findings:

• Successful implantation of a Micra transcatheter pacing system (leadless pacemaker) was achieved.
• The leadless pacemaker provided effective pacing without complications related to the LVAD.

Implications:

• This case suggests leadless pacing is a viable and potentially safer alternative for pacemaker-dependent LVAD patients with transvenous device infections.
• Further research is warranted to establish the broader safety and efficacy of leadless pacemakers in the LVAD population.
• Leadless pacing may reduce the risk of complications associated with transvenous systems in complex cardiac device patients.
