Nonvalvular intravascular devices are crucial for life support but prone to difficult-to-treat infections from multidrug-resistant organisms. This review covers device-related infections, focusing on pathogenesis, immunobiology, and treatment strategies.

Area of Science:

  • Medical Devices
  • Infectious Diseases
  • Immunobiology

Background:

  • Nonvalvular intravascular devices are increasingly used, surpassing prosthetic cardiac valves in prevalence.
  • These life-sustaining devices require removal for cure if infected, often by multidrug-resistant microorganisms.
  • Device-related infections pose significant treatment challenges.

Purpose of the Study:

  • To review the pathogenesis and immunobiology of nonvalvular intravascular device-related infections.
  • To discuss the epidemiology and treatment of infections associated with specific devices.

Main Methods:

  • Literature review and synthesis of current knowledge.
  • Focus on pathogenesis, immunobiology, epidemiology, and treatment.
  • Inclusion of pacemakers, implantable cardioverter defibrillators, catheters, grafts, stents, and ventricular assist devices.

Main Results:

  • Device infections are often caused by multidrug-resistant pathogens, complicating treatment.
  • Understanding pathogenesis and immunobiology is key to managing these infections.
  • Effective treatment strategies are crucial for patient outcomes.

Conclusions:

  • Nonvalvular intravascular device infections represent a growing clinical challenge.
  • Further research into prevention and treatment is warranted.
  • Multidisciplinary approaches are essential for managing these complex infections.
