Percutaneous pulmonary valve implantation in a failed novel biorestorative valved conduit

Percutaneous pulmonary valve implantation

INTRODUCTION Percutaneous pulmonary valve implantation (PPVI) is one of the most exciting recent developments in the treatment of structural heart disease and has evolved as an attractive alternative to surgery in patients with dysfunctional right ventricle-pulmonary artery conduits. Although surgical pulmonary valve replacement is associated with low morbidity and mortality rates, there are ma...

Percutaneous Pulmonary Valve Implantation

Pulmonary regurgitation (PR) is a frequent sequelae after repair of tetralogy of Fallot, pulmonary atresia, truncus arteriosus, Rastelli and Ross operation. Due to patient growth and conduit degeneration, these conduits have to be changed frequently due to regurgitation or stenosis. However, morbidity is significant in these repeated operations. To prolong conduit longevity, bare-metal stenting...

Leaflets have a thickness of approximately 100—150 mm. The stent valves are produced in a dip coating technique (by Mecora GmbH, Aachen, Germany).
