A second-time percutaneous aortic-valve implantation for bioprosthetic failure
We report a case of an 84-year-old man with a history of surgical aortic-valve replacement for chronic aortic regurgitation (AR) who later developed severe prosthetic valve AR. Subsequent treatment with a Corevalve® was unsuccessful with severe AR seen at 3 years after the valve-in-valve procedure. The patient was then successfully treated with a second catheter-based Corevalve® implantation.
متن کاملShort-term performance of mitral valve replacement with porcine bioprosthetic valves in dogs.
Porcine bioprosthetic valves cross-linked with glutaraldehyde and polyepoxy compound were newly developed for mitral valve replacement (MVR) in dogs. Five beagle dogs were performed a left thoracotomy and underwent MVR using the porcine bioprosthetic valves during cardiopulmonary bypass (CPB). A vein catheter inserted into right atrium and a vent catheter inserted into the right ventricle to dr...
متن کاملBioprosthetic Mitral Valve Regurgitation
The usefulness of two-dimensional color-Doppler flow-imaging (2D Doppler) in the detection, localization, and quantitation of bioprosthetic mitral valve regurgitation is uncertain. Mitral bioprostheses, before and after the creation of transvalvular (n = 33), paravalvular (n = 17), or combined (n = 23) defects, were mounted in a pulsed duplication system (flow rates, 2.5-6.5 1/min; pulse rate, ...
متن کاملTranscatheter heart valve in valve implantation with Edwards SAPIEN bioprosthetic valve for different degenerated bioprosthetic valve positions (First Iranian ViV report with mid-term follow up)
Introduction: After early successful experience with transcatheter aortic valve replacement (TAVR), concept of transcatheter implantation of a new valve within a failing bioprosthetic valve emerged. Valve-in-valve (ViV) implantation seems to be a simpler option for high risk surgical patients. Methods: We performed five ViV procedures in different valve positions. We included patients with fail...
متن کاملClinical outcomes of pulmonary valve replacement surgery in pediatrics: a single-center experience long-term study
Introduction: Heart valve disease in pediatricsis an increasing global concern, especially in developing countries. This study aims to determine the clinical outcomes of pulmonary valve replacement (PVR) surgery in pediatrics. Methods: The authors retrospectively identified all pediatrics undergoing PVR surgery at Imam Reza hospital (Mashhad, Iran) between 2000 and 2020. Their medical records...
