Abstract

We report the first use of a single 100-mm long custom-made version of the Optimus-CVS® balloon-expandable PTFE-covered XXL (15-Zig) stent (AndraTec, GmbH) to eliminate sinus venosus defect left-to-right shunt and redirect anomalous right pulmonary veins blood flow through a new walled channel to the left atrium. Anatomical feasibility and strategy decision were guided by ex-vivo procedure simulation on the patient-specific 3D printed heart model and in-vivo balloon interrogation. Modified procedural and implantation techniques are detailed. Immediate and one-month follow-up showed excellent outcomes.
