Abstract

A prosthetic valve with fluoroscopic properties for precise placement of the prosthetic valve in a human stenosed aortic orifice is disclosed. The prosthetic valve comprises a support frame having a distal and a proximal end, and three adjacently placed rows of hexagonal cells (namely an upper, middle and a lower row). The upper row occupies 50-55% of total length of the support frame. The supportframe of the prosthetic valve under fluoroscopy comprises a plurality of light bands and dark bands alternating with each other along the length of the support frame. Further, a second dark band fromthe distal end of the support frame is bisected by aortic annular plane on placement in orthotopic position of a human stenosed aortic orifice. The prosthetic valve offers advantages such as minimalprotrusion in left ventricle and minimal obstruction of prosthetic valve to ostia of coronary arteries.

Description

technical field [0001] The present invention relates to artificial valves. More specifically, the present invention relates to an artificial heart valve implanted by percutaneous catheterization techniques. Background technique [0002] The human heart is a hollow organ with four chambers separated by corresponding valves (aortic, pulmonary, tricuspid and mitral). Responding to pressure gradients created by the contraction and relaxation of the four chambers, these valves open and close in a cyclical rhythm to allow blood to flow in specific directions. These valves consist of leaflets (leaflets) attached to an annulus. Thus, with the help of the leaflets, the native heart valve plays a key role in ensuring the forward flow of blood and the adequate supply of blood. [0003] The valves of the human heart can suffer from a variety of diseases that lead to cardiac dysfunction, resulting in serious cardiovascular hazard or death. Diseased heart valves may be narrowed and / or...
