Cardiac Device Infection

As the use of pacemakers, implantable cardioverter defibrillators, and cardiac resynchronization devices expands, Cardiac Device Infection has become a critical complication with substantial morbidity and mortality. This session examines the spectrum of infection—from superficial pocket inflammation to systemic device-related endocarditis—and outlines evidence-based strategies for diagnosis, treatment, and prevention. Participants will review risk factors, microbiology, and clinical presentations, learning how to recognize early warning signs and differentiate sterile inflammation from true infection. The content is highly practical, geared toward cardiologists, electrophysiologists, infectious disease specialists, and device clinic teams.

Growing interest in a dedicated cardiology conference reflects the need for clearer, multidisciplinary pathways. This session discusses appropriate use of blood cultures, inflammatory markers, and advanced imaging such as transesophageal echocardiography and PET-CT to identify lead and valvular involvement. Attendees will learn when conservative management is inadequate and how to time complete system extraction, including leads, to maximize cure rates. Real-world case discussions highlight scenarios such as late pocket infections, occult bacteremia with implanted hardware, and device infection in frail or high-risk patients where procedural risk must be weighed carefully.

A central focus is best practice in CIED infection management (cardiac implantable electronic device infection). Participants will explore recommended antibiotic regimens, timing of re-implantation, and options for temporary pacing or defibrillation support during the interval. The session emphasizes the importance of referral to experienced extraction centers, where surgical and percutaneous expertise can be combined for complex cases. Preventive strategies—antibiotic prophylaxis, pocket preparation, device selection, and use of antibacterial envelopes—are discussed in detail to help reduce first-time and recurrent infections.

The session also covers system-wide implications, including the role of device infection registries, standardized documentation, and quality improvement initiatives. Attendees will learn how to design institutional protocols that streamline referrals, clarify responsibilities among specialties, and ensure timely intervention. By the end, participants will have a comprehensive framework for recognizing, treating, and preventing cardiac device infections, ultimately safeguarding the benefits of device therapy for patients who depend on them.

Diagnostic and Treatment Principles in Device Infection

Recognizing Clinical Presentations

  • Identifying local pocket changes, systemic symptoms, and bacteremia patterns that suggest device involvement.
  • Distinguishing superficial wound issues from deep pocket infection or endocarditis.

Imaging and Microbiological Workup

  • Using echocardiography and advanced imaging to detect lead vegetations or valvular involvement.
  • Obtaining appropriate cultures before antibiotics to guide targeted therapy.

Extraction and Re-Implantation Strategies

  • Determining when complete system removal is mandatory for cure.
  • Planning timing and site of new device placement, considering alternative systems when needed.

Multidisciplinary Coordination and Prevention

  • Aligning cardiology, electrophysiology, infectious disease, and surgery teams around unified pathways.
  • Implementing peri-procedural protocols that reduce infection risk at the time of implantation.
