Percutaneous Pulmonary Valve Implantation
نویسندگان
چکیده
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 in the right ventricular outflow tract (RVOT) obstruction has been performed. Stenting the RVOT can reduce the right ventricular pressure and symptomatic improvement, but it causes PR with detrimental effects on the right ventricle function and risks of arrhythmia. Percutaneous pulmonary valve implantation has been shown to be a safe and effective treatment for patients with pulmonary valve insufficiency, or stenotic RVOTs.

متن کاملCorrelation between RVOT sizing and RV function and volumes in patients with repaired tetralogy of Fallot undergoing routine CMR follow-up: is there a better candidate for percutaneous pulmonary valve implantation?
Background CMR is the established non-invasive tool for routine RV functional and morphological assessment in repaired tetralogy of Fallot (rTOF) patients. 3D anatomical data of the RVOT are routinely performed to better address indications for Pulmonary Valve Replacement (PVR), either surgical or percutaneous. The aim of this crosssectional analysis is to improve the ability of CMR to identify...

Background In patients with congenital heart defects, restoration of the connection between the right ventricle (RV) and the pulmonary artery (PA) by surgical or percutaneous valved conduit implantation is a common procedure. Flow characteristics in such conduits are complex, therefore the aim of this study was demonstrating the potential application of 4D MRI flow for the comprehensive assessm...

Percutaneous pulmonary valve implantation now has a key role in the setting of dysfunctional right ventricle-to-pulmonary artery conduits or failing bioprosthetic pulmonary valves. However, despite the excellent results obtained with the two devices available currently (the Melody(®) valve [Medtronic Inc., Minneapolis, MN, USA] and the Edwards SAPIEN(®) valve [Edwards Lifesciences, Irvine, CA, ...

OBJECTIVES We report our experience of percutaneous valve insertion in pulmonary position in humans. BACKGROUND Over the past 40 years, prosthetic conduits have been developed to surgically establish continuity between the right ventricle and the pulmonary artery. However, stenosis and insufficiency of the conduit due to valvular degeneration or panus ingrowth frequently occur, limiting patient...
