Percutaneous pulmonary valve replacement: autologous tissue-engineered valved stents.
AIMS Percutaneous implantation has already been used clinically and is a great option for treating young patients. The use of autologous tissue-engineered valved stents might solve the problem of degeneration and limited durability of biological heart valves. METHODS AND RESULTS Porcine pulmonary heart valves and small intestinal submucosa were obtained from a slaughterhouse. The intestinal s...
متن کاملReplacement of the ascending aorta, aortic root, and valve with a novel stentless valved conduit.
PURPOSE Biologic valved-conduit grafts avoid the need for anticoagulation and can exploit the excellent hemodynamic performance of stentless valves. Incorporation of sinuses of Valsalva into the neoaortic root can improve the function of the stentless valves. DESCRIPTION Here we present a novel prefabricated stentless valved conduit incorporating sinuses of Valsalva and describe the technique...
متن کاملDouble-crowned valved stents for off-pump mitral valve replacement.
OBJECTIVE An animal model has been designed to assess the feasibility of off-pump mitral valve replacement using valved stents. METHODS Glutaraldehyde-preserved homograft was sutured inside a prosthetic tube (Dacron). Then, two self-expandable nitinol Z-stents were sutured on the external surface of the prosthesis in such a way to create two self-expanding crowns for fixation. In adult pigs a...
متن کاملPercutaneous valve replacement: a novel low-profile polyurethane valved stent.
Fig. 1. (a) Oblique view from top of a self-expanding nitinol stent (length 28 mm, diameter 24 mm, Nitinol Devices & Components Inc., Fremont, CA, USA) containing a three leaflet polyurethane valve. Leaflets have a thickness of approximately 100—150 mm. The stent valves are produced in a dip coating technique (by Mecora GmbH, Aachen, Germany). (b) Low-profile polyurethane valved stent was folde...
متن کاملAortic root replacement with a valved conduit containing a stented xenograft.
The Bentall operation is a well-established procedure for aortic root replacement, generally contemplating the use of a mechanical valve substitute. We have devised a simple modification by which a stented bioprosthesis is sutured inside, rather than at the extremity, of a vascular tube graft. This facilitates the technique of implantation and may simplify a redo procedure in case of valve fail...
