Multi-center, Observational Registry with Retrospective Enrollment and Prospective Follow-up. The aim of the registry is to document the feasibility and safety of implanting an Edwards SAPIEN XT transcatheter heart valve in the pulmonic position.
A malfunction or dysplasia of the pulmonary valve or the right ventricular outflow tract (RVOT) is one of the major components of the cardiac physiology in many congenital heart defects. Surgical correction of complex heart defects often includes some form of surgical repair or replacement of the native RVOT by biological valves such as homograft, bioprosthesis or Xenografts (i.e., Contegra conduits). Typical examples are tetralogy of Fallot (TOF) or double outlet right ventricle (DORV), pulmonary stenosis (PS), pulmonary atresia (PA), truncus arteriosus (TA), transposition of the great arteries (TGA) with PS (Rastelli's operation), absent pulmonary valve syndrome (Miller-Lev-Paul), Ross surgery for aortic valve disease and others. The repaired or replaced pulmonary valve however often becomes dysfunctional later on and many patients require surgical revisions of the RVOT with pulmonary valve replacement within 10 years of primary intervention. TPVI provides a less invasive alternative to surgery in patients with right ventricular-to-pulmonary artery (RV-PA) conduit dysfunction. Early results of percutaneous pulmonary valve implantation (PPVI) showed that it is a promising procedure compared to a conventional surgical intervention. Meanwhile, pre-stenting of the RVOT before PPVI is routinely performed, enabling PPVI in various anatomies.
