Authors' 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

Safety

Major adverse events (stroke, bleeding, infection, respiratory failure, renal and hepatic dysfunction)

More likely with CHD than non-CHD
