Infections in Patients with Mechanical Circulatory Support

Area of Science:

• Cardiology
• Infectious Diseases
• Transplantation Medicine

Background:

• Mechanical circulatory support (MCS) devices are crucial for end-stage heart failure.
• Patients with MCS are at increased risk of infection due to device invasiveness, implantation, and biofilm formation.
• Existing infection definitions lacked standardization, complicating research and clinical practice.

Purpose of the Study:

• To review the new International Society for Heart and Lung Transplantation (ISHLT) mechanical circulatory support device infection definitions.
• To describe the epidemiology, diagnosis, and management of both durable and acute MCS device infections.
• To highlight the importance of a multidisciplinary approach and address transplantation timing in infected patients.

Main Methods:

• Literature review of recent studies and guidelines on MCS device infections.
• Analysis of the newly proposed ISHLT infection definitions.
• Synthesis of current knowledge on epidemiology, diagnosis, and management strategies.

Main Results:

• New ISHLT definitions provide standardized criteria for durable and acute MCS device infections.
• Infections are a significant complication, impacting patient morbidity and mortality.
• Effective management requires a coordinated, multidisciplinary team approach.

Conclusions:

• Standardized definitions are crucial for consistent diagnosis and management of MCS infections.
• A multidisciplinary strategy is essential for optimizing patient care and outcomes.
• Further research is needed to refine treatment protocols and address transplantation timing in infected patients.
