摘要:
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 support frame 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 from the 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 minimal protrusion in left ventricle and minimal obstruction of prosthetic valve to ostia of coronary arteries.
