Background:
Patients with a ventricular assist device (VAD) who are awaiting heart transplant (HTx) are susceptible to infections. Such infections, especially at the site of the VAD, may increase the risk of severe post-transplant infections and mortality. Information on the characteristics of VAD-specific infections and outcomes in HTx recipients after prolonged periods of LVAD therapy is scarce.
Purpose:
We aimed to assess the impact of active VAD-specific infections on the incidence of early post-transplant infections and patient survival.
Methods:
We conducted a retrospective review of adult HTx cases at our center between April 2011 and October 2020. Informed consent was waived due to study design. A total of 86 patients were included in this study, among whom 94.2% (n = 81) were bridged with a VAD, and the median VAD support period was 1089 days.
Results:
Patients with active VAD-specific infections were significantly more likely to develop severe acute mediastinitis [odds ratio (OR) 14.8, 95% confidence interval (CI) 4.83-45.4, P < .01]. Active VAD infections were significantly related to increased length of intensive care unit stay (22.1 days vs 13.0 days, P = .016) and longer mechanical ventilation periods (324.7 hours vs 113.2 hours, P = .03). The 30-day survival rates for patients with and without post-transplant infections were 100% and 97.1%, respectively.
Conclusion:
Compared to other risk factors, the presence of active VAD-specific infections increases the risk of early post-heart transplant infections and morbidity, without affecting mortality.

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
