Transcatheter pulmonary valve implantation: A cross-sectional US experience

Abstract

More than a decade ago Bonhoeffer et al. [ [1] Bonhoeffer P. Boudjemline Y. Saliba Z. Merckx J. Aggoun Y. Bonnet D. Acar P. Le Bidois J. Sidi D. Kachaner J. Percutaneous replacement of pulmonary valve in a right-ventricle to pulmonary-artery prosthetic conduit with valve dysfunction. Lancet. Oct 21 2000; 356: 1403-1405 Abstract Full Text Full Text PDF PubMed Scopus (821) Google Scholar ] demonstrated implantation of transcatheter pulmonary valve (TPV) in a RVOT (Right Ventricular Outflow Tract) conduit with a device comprising a balloon-expandable stent with mounted bovine jugular venous valve. US food and Drug Administration (FDA) approved modified version of the original device, the Melody valve (Medtronic Inc, Minneapolis, Minnesota) in 2010 after the original Investigational Device Exemption (IDE #G050186) trial [ [2] Zahn E.M.
