Analysis of 82 Children Supported With Pulsatile Paracorporeal Ventricular Assist Device: Comparison of Patients With Biventricular Versus Univentricular Circulation.
Seminars in thoracic and cardiovascular surgery(2022)
摘要
We reviewed outcomes in 82 consecutive children supported with the Berlin Heart pulsatile ventricular assist device (VAD), comparing those with functionally univentricular circulation (n = 34) to those with biventricular circulation (N = 48). The primary outcome was mortality. Kaplan-Meier methods and log-rank tests were used to assess group differences in long-term survival. T-tests using KM-estimated survival proportions and standard errors were used to compare groups at specific time points. 48 biventricular patients were supported (Age: median = 1.4 years, range = 17 days-17.7 years; Weight [kilograms]: median = 9.4, range = 3.1-112), including 43 BiVAD, 4 LVAD only, and 1 LVAD converted to BiVAD. In biventricular patients, duration of VAD support [days]: median = 97, range = 4-315. Of 48 biventricular patients, 35 underwent heart transplantation, 7 died on VAD, 5 weaned off VAD (1 of whom underwent heart transplantation 334 days after weaning), and 1 is still on VAD. 34 univentricular patients were supported with single VAD (sVAD) (Age: median = 38.5 days, range = 4 days-13.3 years; Weight [kilograms]: median = 3.98, range = 2.4-32.6). In univentricular patients, duration of VAD support [days]: median = 138, range = 4-554. Of 34 univentricular patients, 22 underwent transplantation, 11 died on VAD, and 1 is still on VAD. One-year survival 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 was 79.7% (95% CI=68.6-92.6%) in biventricular patients and 50.5% (95% CI = 35.0-73.0%) in univentricular patients, p = 0.010. 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.
