Abstract

The invention provides a heart valve prosthesis which is applied to the technical field of interventional medical prostheses. In the heart valve prosthesis provided by the invention, under the condition that the sizes of the valve leaflet connecting parts are the same, compared with the prior art that a closing hole is formed in a valve leaflet fixing structure; according to the embodiment of the invention, a plurality of valve leaflet connecting parts are arranged in the stent main body in the heart valve prosthesis, each row of holes of each valve leaflet connecting part at least comprises a double-row hole structure of a non-closed hole, so that more suture holes which are more compactly distributed can be formed in a valve leaflet fixing structure, connecting points of the valve leaflet and the stent are increased, and the valve leaflet fixing structure is more compact. The connecting strength of the valve leaflet and the stent is enhanced under the condition that the outer diameter of the stent is not increased after compression, and then the stability of the heart valve prosthesis in the working state is improved.

Description

technical field [0001] The invention relates to the technical field of interventional medical prostheses, in particular to a heart valve prosthesis. Background technique [0002] The heart contains four chambers, the left atrium and left ventricle are located on the left side of the heart, and the right atrium and right ventricle are located on the right side of the heart. The ventricular inflow tract structure is formed between the atrium and the ventricle, the left ventricle and the aorta form the left ventricular outflow tract structure, and the right ventricle and the pulmonary artery form the right ventricular outflow tract structure. There are valves with a "one-way valve" function at the ventricular inflow tract structure and the ventricular outflow tract structure to ensure the normal flow of blood in the cardiac cavity. When there is a problem with this valve, the hemodynamics of the heart changes and the heart functions abnormally, called valvular heart disease. ...
