CONGENITAL – Original SubmissionAnalysis of 82 Children Supported With Pulsatile Paracorporeal Ventricular Assist Device: Comparison of Patients With Biventricular Versus Univentricular Circulation
Section snippets
INTRODUCTION
The survival of neonates, infants, children, and adults with congenital heart disease continues to improve after surgical palliation and repair;1,2 however, certain subsets of patients remain at high risk and will ultimately require cardiac transplantation. As the demand for pediatric donor hearts increases, the need for utilizing ventricular assist devices (VADs) as a bridge to transplantation in neonates, infants, and children also increases. Furthermore, as experience with pediatric VADs
Patients
This analysis includes all 82 consecutive patients supported with the Berlin Heart pulsatile VAD at University of Florida, with the first patient cannulated on September 29, 2006 and the most recent patient in this consecutive series cannulated on March 17, 2022. (These 82 patients underwent 83 separate episodes of support with the Berlin Heart because one biventricular child with myocarditis was successfully bridged to transplant, and then 615 days after the original transplant underwent a
RESULTS
Eighty-two consecutive children less than 18 years of age were supported with the Berlin Heart VAD (Age [years]: mean ± SD = 3.44 ± 4.75, median = 191 days, range = 4 days–17.7 years; Weight [kilograms]: mean ± SD = 14.8 ± 19.8, median = 5.75, range = 2.43–112), with the first patient cannulated on September 29, 2006 and the most recent patient cannulated on March 17, 2022. 48 patients with biventricular circulation were supported (43 BiVAD, 4 LVAD only, and 1 LVAD converted to BiVAD) and 34
DISCUSSION
In our single institutional analysis of 82 neonates, infants, and children supported with pulsatile VAD, overall longitudinal Kaplan-Meier estimates for survival after VAD insertion were 73.3% (95% CI = 64.1–83.8%) at one-year and 68.3% (95% CI = 58.4–79.8%) at five-years. One-year survival after VAD insertion was 82.7% (95% CI = 72.4–94.4%) in biventricular patients and 59.7% (95% CI = 44.9–79.5%) in univentricular patients, p = 0.026. Five-year survival after VAD insertion was 79.7% (95%
CONCLUSIONS
Pulsatile VAD facilitates bridge to transplantation in neonates, infants, and children with functionally univentricular circulation; however, survival is worse than in patients with biventricular circulation. One-year survival after VAD insertion was 82.7% (95% CI = 72.4–94.4%) in biventricular patients and 59.7% (95% CI = 44.9–79.5%) in univentricular patients, p = 0.026. Five-year survival after VAD insertion was 79.7% (95% CI = 68.6–92.6%) in biventricular patients and 50.5% (95%
