Abstract:
Fenestration transcatheter closure is widely considered to eliminate persistent right-to-left shunt after Fontan surgeries. Three consecutive children with stage III-palliated univentricular hearts recently underwent successful endovascular fenestration closure using 43 mm/Large Optimus-CVS™ that were implanted using the new Altosa-XL™ PTA balloon catheters (AndraTec GmbH). The procedure was fast with no complication and patients were discharged the following day with complete shunt closure. One-month follow-up confirmed excellent outcomes. This report aims to highlight and discuss the competitive advantages of these promising new materials in this particular intervention.
