Intravascular device infections: epidemiology, diagnosis, and management

Area of Science:

• Cardiology
• Infectious Diseases
• Biomedical Engineering

Background:

• Intravascular devices, including pacemakers, implantable cardioverter-defibrillators (ICDs), left ventricular assist devices (LVADs), and prosthetic vascular grafts, are crucial for managing serious cardiac and vascular conditions.
• The increasing use of these life-saving devices has led to a rise in associated infectious complications.
• These infections pose significant risks, contributing to patient morbidity and mortality.

Purpose of the Study:

• To review the existing clinical literature on the epidemiology, diagnosis, and management of infections related to intravascular devices.
• To synthesize current knowledge regarding the origins, progression, and treatment outcomes of these device-related infections.

Main Methods:

• A comprehensive review of clinical literature was conducted.
• The review focused on studies detailing the epidemiology, diagnostic approaches, and therapeutic strategies for intravascular device infections.

Main Results:

• Intravascular device infections are commonly initiated by skin flora contamination during implantation, potentially spreading to deeper tissues.
• Infections involving the intravascular or intracardiac portions of devices are associated with high morbidity and mortality.
• Antibiotic therapy alone is often insufficient for cure, frequently necessitating device removal.

Conclusions:

• Effective management of intravascular device infections requires a multidisciplinary approach, often involving device explantation.
• There is a critical need for well-designed, randomized controlled trials to establish evidence-based guidelines for antimicrobial therapy.
• Current recommendations include targeted antibiotic therapy (4-6 weeks) and device removal in cases of infection.
