摘要:
Cardiac valve prosthesis (20) for replacing a patient's natural valve, the cardiac valve being deployable with a deployment system (10), where the cardiac valve prosthesis (20) comprises a generally cylindrical stent vascular stent support ( 102) having a plurality of diamond-shaped expandable cells (110), and having a proximal end (103), a proximal part (104), a central part (105), a distal part (106) and an end distal (107), where the diamond-shaped cells (110) have edges (111), where the size of the cells (110) in the distal part (106) is larger than the size of the cells (110) in the proximal part (104); and a valve (118) having a plurality of leaflets (119), and a plurality of commissure points (120), and where the valve (118) is mounted on the stent support (102), so that the valve (118) forms the inner surface of the stent support (102), which in the proximal part (104) forms a sealing zone, where the inner surface of the cylindrical stent support (102) is lined by the valve (118), that the valve (118), in a region (108) between the distal end (107) and the central part (105), is fixed to the stent support (102) by the commissure points (120) , and that the stent support (102) has, in a region (108) between the distal end (107) and the central part (105), a valveless part, characterized in that, at the distal end (107) of the stent support (102), there are free edges (112) at least three of which have a part and T-shaped end (114), because in addition the central part (105) of the stent support (102) carries radiopaque markers (116) and because at the distal end (107), the cylindrical shape of the support Stent stent (102) in the part without valve, has a diameter that is reduced compared to the remaining cylindrical shape of the stent stent (102).Prótesis de válvula cardiaca (20) para sustitución de una válvula natural de un paciente, siendo la válvula cardiaca desplegable con un sistema de despliegue (10), donde la prótesis de válvula cardiaca (20) comprend
