Authors' conclusion

In this large congenital ASD device trial, the GCA had acceptable results. WFFs, although common, did not result in any clinical sequelae.

Study context

Population
Patients undergoing attempted ostium secundum atrial septal defect (ASD) closure (median age 10.4 years, median weight 35.0 kg)526 technical successes
Participants
569 patients
Outcome
Closure success and composite clinical success (deployment/retention of device, safety, and closure)
Follow-up
6 months
