Re-interventions Following Patent Ductus Arteriosus Stenting During the Inter-stage Period

Stenting of the arterial duct is an established alternative to surgical palliation for infants with duct-dependent congenital heart disease but is often associated with the need for reintervention to achieve a result through to the next stage surgery. The relatively high rate of interstage reintervention is partly related to increased anatomic and procedural complexity but with growing experience planned reinterventions to optimize vessel and somatic growth is also possible. We discuss the challenges encountered when reintervening on stented ducts and technical considerations to increase procedural efficiency and mitigate complications in these small infants.
