BACKGROUND: Cerebralvascular accidents (CVA) are common complications of pediatric ventricular assist devices (VADs). We employed the Pediatric Interagency Registry for Mechanical Circulatory Support (Pedimacs) to investigate rates, risk factors, and outcomes of CVA in pediatric patients supported on VAD.
METHODS: Analysis of Pedimacs (September 2012-June 2019) data to determine rates of all neurologic events and specifically CVA. Risk factors were determined by a multiphase parametric hazard model. Outcomes of patients with CVA were compared with patients without CVA.
RESULTS: We included 662 patients in our analysis. In total, 87 CVA events occurred in 71 patients (10.7%). The proportion of patients with CVA was highest in the paracorporeal pulsatile group (16.9%) followed by the paracorporeal continuous group (10.4%). However, the rate of CVA was lower in the paracorporeal pulsatile group compared to the paracorporeal continuous group (6.4 vs 11.1 events/100 patient months), which reflects differences in support duration. Ascites, higher patient profile groups, and implants within small volume centers were associated with the occurrence of CVA. Our analysis found that the recent era (i.e., June 2017), and intracorporeal continuous implants were protective. Mortality was higher in patients following a CVA diagnosis compared to those without a CVA diagnosis.
CONCLUSIONS: CVA continues to be a problem in pediatric VAD support, though the overall percent is now <11%. Data from the most recent era are encouraging, but CVA is still significantly associated with mortality. Future efforts should focus on pre-implant and early support periods.
