Data on ventricular assist device (VAD) outcomes in infants with stage 1 single ventricle (SV) palliation are limited. We examined the Advanced Cardiac Therapies Improving Outcomes Network (ACTION) registry for outcomes of pre/poststage 1 SV patients undergoing VAD implantation between March 2018 and October 2020. Data are collected from 32 centers and major adverse events undergo central adjudication. During the study period, 30 stage 1 SV patients underwent VAD implant with median age of 0.9 months (range 0.1-25) and weight 3.7 kg (2.4-17). Preimplant illness severity was high: ventilator support (90%), ECMO (30%), prior cerebral vascular accident (CVA, 23%), and dialysis (13%). Devices used included paracorporeal pulsatile (50%), paracorporeal continuous-flow (37%), and multiple devices (13%). Median support duration was 56 days (range 3-246). A positive clinical outcome (transplanted or weaned) was attained in 63% (63% transplanted, 37% mortality, 0% weaned). VAD adverse events included: major infection (43%), neurologic dysfunction (any = 30%; CVA = 20%), major bleeding (17%), renal dysfunction (13%), and device malfunction (3%). In conclusion, stage 1 SV patients undergoing VAD support have high preimplant illness severity and complexity, as well as significant morbidity and mortality postimplant. A variety of devices and strategies are employed by centers to support this challenging population.
