First in human experience of a new self-expandable percutaneous pulmonary valve implantation using knitted nitinol-wire and tri-leaflet porcine pericardial valve in the native right ventricular outflow tract.

Abstract

Balloon-expandable percutaneous pulmonary valve systems using the Melody and Edwards SAPIEN transcatheter heart valves have been increasingly used instead of surgically implantable pulmonary valves. However, limited patients with right ventricular outflow tract (RVOT) lesions are suitable candidates for percutaneous pulmonary valve implantation (PPVI) using these systems after surgical correction of tetralogy of Fallot. Therefore, larger self-expandable valved-stents are being developed for native RVOT lesions. We report the first-in-human case of a new self-expandable PPVI in a patient with a native RVOT lesion using a newly made knitted nitinol-wire stent mounted with a tri-leaflet porcine pericardial valve developed in South Korea. © 2017 Wiley Periodicals, Inc.
