Outcomes for Children With Congenital Heart Disease Undergoing Ventricular Assist Device Implantation: An ACTION Registry Analysis
Main finding · Adjusted survivalResult — go to the resultHazard ratio 2.05 95% CI 1.39–3.02Authors' conclusion
CHD patients are more likely in extremis at VAD implantation and experience higher rates of adverse events and worse survival compared to those with non-CHD.
Study context
- Population
- Children undergoing ventricular assist device (VAD) implantation in the ACTION network, April 2018 to February 2023
- Participants
- 966 children
- Exposure
- CHD vs non-CHD; univentricular vs biventricular CHD
- CHDn = 352
- Univentricular CHDn = 230
- Outcome
- Postimplantation survival and adverse events

- Preimplantation characteristics, CHD vs non-CHD: P < 0.05 for all
eGFR, univentricular vs biventricular CHD
- No other significant differences in clinical characteristics
Safety
Major adverse events (stroke, bleeding, infection, respiratory failure, renal and hepatic dysfunction)
- More likely with CHD than non-CHD
