Adverse events in children implanted with ventricular assist devices in the United States:Â Data from the Pediatric Interagency Registry for Mechanical Circulatory Support (PediMACS)

In this study cohort, the overall rate of early adverse events (within 90 days of implantation) was 86.3 events per 100 patient-months, and of late adverse events it was 20.4 events per 100 patient-months. The most common adverse events in recipients of pulsatile VADs were device malfunction, neurologic dysfunction, bleeding and infection. For continuous-flow VADs, the most common adverse events were infection, bleeding, cardiac arrhythmia, neurologic dysfunction and respiratory failure. Compared with an adult INTERMACS cohort, the overall rate and distribution of adverse events appears similar.
