Abstract:
A case of a septic paradoxic embolus due to an infected pacemaker lead associated with a patent foramen ovale (PFO) is described. Treatment consisted of immediate intracardiac embolectomy, pericardial patch closure of the PFO, total removal of the infected pacemaker lead and generator, and placement of a new permanent epicardial lead pacemaker system.
Insights
A septic paradoxical embolus from an infected pacemaker lead and patent foramen ovale (PFO) was treated. The successful intervention involved embolectomy, PFO closure, lead removal, and new pacemaker system implantation.
Area of Science:
- Cardiology
- Infectious Diseases
- Medical Devices
Background:
- Pacemaker leads can be a source of infection, leading to complications like septic emboli.
- Patent Foramen Ovale (PFO) is an atrial septal defect that can facilitate paradoxical embolism.
Observation:
- A case of septic paradoxical embolus was identified.
- The embolus originated from an infected pacemaker lead.
- The patient had an associated patent foramen ovale (PFO).
Findings:
- Successful intracardiac embolectomy was performed.
- Pericardial patch closure effectively addressed the PFO.
- Complete removal of the infected pacemaker lead and generator was achieved.
- A new permanent epicardial lead pacemaker system was successfully implanted.
Implications:
- This case highlights a rare but serious complication of pacemaker use.
- Multimodal surgical intervention can effectively manage infected pacemaker leads and associated paradoxical emboli.
- Prompt diagnosis and treatment are crucial for favorable patient outcomes.
