Infections during left ventricular assist device support do not affect posttransplant outcomes

Area of Science:

• Cardiology
• Infectious Disease
• Transplantation

Background:

• Infections during ventricular assist device (VAD) support may impact transplant survival.
• The post-transplant consequences of VAD-associated infections require further investigation.

Purpose of the Study:

• To evaluate the impact of an outpatient program, newer VAD devices, and updated infection management on post-transplant outcomes.
• To assess infection-related risks and survival in VAD patients compared to non-VAD controls.

Main Methods:

• Retrospective analysis of 86 VAD patients and 50 matched non-VAD control patients.
• Comparison of peritransplant and post-transplant infection rates and actuarial survival at 6 months and 3 years, respectively.
• Infection defined by clinical signs and positive culture requiring intervention.

Main Results:

• A high incidence of infection during VAD support did not affect pre- or post-transplant mortality or overall survival.
• LVAD recipients experienced a lower freedom from infection compared to controls (P<0.05).
• Three-year survival rates were comparable: 79% for LVAD recipients and 87% for controls.

Conclusions:

• VADs increase early post-transplant infection risk but do not negatively impact transplantability or patient survival.
• Effective infection control strategies in both inpatient and outpatient settings likely mitigate adverse outcomes.
• Modern VAD support and management protocols contribute to favorable long-term survival post-transplant.
