| Summary: | Abstract Pediatric pulmonary arterial hypertension (PAH) can present with a wide spectrum of disease severity. Pulmonary hypertension (PH) crises can lead to acute decompensation requiring extracorporeal membrane oxygenation (ECMO) support, including extracorporeal cardiopulmonary resuscitation (eCPR). We evaluated outcomes for pediatric PH patients requiring ECMO. A single‐institution retrospective review of pediatric PAH patients with World Symposium on PH (WSPH) groups 1 and 3 requiring ECMO cannulation from 2010 through 2022 (n = 20) was performed. Primary outcome was survival to hospital discharge. Secondary outcomes were survival to decannulation and 1‐year survival. Of 20 ECMO patients, 16 (80%) survived to decannulation and 8 (40%) survived to discharge and 1 year follow up. Of three patients who had two ECMO runs; none survived. There were five patients who had eCPR for the first run; one survived to discharge. The univariate logistic regression model showed that venovenous ECMO was associated with better survival to hospital discharge than venoarterial ECMO, (OR: 0.12, 95% CI: 0.01–0.86, p = 0.046). PH medications (administered before, during, or after ECMO) were not associated with survival to discharge. For children with decompensated PAH requiring ECMO, mortality rate is high, and management is challenging. While VA ECMO is the main configuration for decompensated PH, VV ECMO could be considered if there is adequate ventricular function, presence of a systemic to pulmonary shunt, or an intercurrent treatable illness to improve survival to discharge. A multidisciplinary approach with requisite expertise should be utilized on a case‐by‐case basis until more reliable data is available to predict outcomes. |
