Treatment of Infected Cardiac Implantable Electronic Devices

Area of Science:

• Cardiology
• Infectious Diseases
• Biomedical Engineering

Background:

• Cardiac implantable electronic devices (CIEDs), including pacemakers and left ventricular assist devices (LVADs), have seen increased utilization over the last 50 years.
• The expanding applications of CIEDs have led to a concurrent rise in device-related infections.
• Managing CIED infections is critical due to their increasing prevalence.

Purpose of the Study:

• To review current treatment strategies for CIED infections.
• To highlight the importance of early pathogen identification for targeted antimicrobial therapy.
• To discuss novel therapeutic approaches for CIED infection management.

Main Methods:

• Review of existing literature and treatment algorithms for CIED infections.
• Discussion of diagnostic methods for identifying causative organisms.
• Analysis of conventional and novel treatment modalities, including device explantation and device salvage techniques.

Main Results:

• Early diagnosis of infection is essential for effective treatment planning.
• Surgical debridement and device explantation remain standard care for many CIED infections.
• Device salvage techniques, such as serial wound washouts and antibiotic-eluting beads, offer an alternative for select patients.

Conclusions:

• Novel strategies focus on salvaging CIEDs, particularly for patients unsuitable for surgery or those who have not responded to conventional treatments.
• The choice between explantation and device salvage depends on patient factors and infection severity.
• Continued research into effective CIED infection management is warranted.
