Remnant Pacemaker Lead Tips after Lead Extractions in Pacemaker Infections

Area of Science:

• Cardiology
• Infectious Diseases
• Medical Device Management

Background:

• Cardiovascular implantable electronic devices (CIEDs) are crucial for managing cardiac arrhythmias.
• CIED infections necessitate device and lead removal, but complete lead extraction is not always feasible.
• Optimal management strategies for CIED infections with retained lead material remain unclear.

Purpose of the Study:

• To describe the clinical outcomes and management of patients with CIED infections and retained lead fragments after attempted extraction.

Main Methods:

• Case report detailing five patients with CIED infections and remnant lead tips post-extraction.
• Review of management approaches, including antibiotic therapy duration and monitoring.
• Assessment of clinical outcomes, including infection recurrence and lead fragment migration.

Main Results:

• Two patients with localized pocket infections received >2 weeks of antibiotics.
• Three patients with infective endocarditis received >4 weeks of antibiotics.
• One lead tip migrated to the pulmonary artery without complications; only one patient had infection recurrence.

Conclusions:

• Antibiotic therapy can be effective for managing CIED infections with retained lead fragments.
• Retained lead fragments may not always lead to adverse outcomes or infection recurrence.
• Further research is needed to establish definitive management guidelines for these complex cases.
