Problems solved by technology

However, the current mitral prosthetic heart valve will occupy part of the left ventricular outflow tract space after the anterior leaflet of the valve stent is implanted, causing the valve stent to obstruct the blood flow out of the left ventricle, and easily lead to complications such as heart failure

Abstract

An embodiment of the present application provides a transcatheter mitral valve stent, wherein the transcatheter mitral valve stent includes an inflow section and an outflow section, the outflow section includes the front part of the outflow section and the rear part of the outflow section, and the height of the front part of the outflow section is It is higher than the height of the rear part of the outflow section; there is a preset angle between the end surface of the outflow section and the height direction of the stent; through this design, the outflow section can be kept away from the left ventricular outflow tract to reduce the impact on the left ventricle after valve implantation The blocking effect of blood flow is beneficial to improve heart function and relieve pain of patients.

Description

technical field [0001] The present application relates to the technical field of transcatheter artificial heart valves, in particular to a transcatheter mitral valve stent. Background technique [0002] The mitral valve is an important organ in the blood circulation process of the human body. It is used to open or close to ensure that the blood from the left atrium flows to the left ventricle. Due to the aging or disease effects of the valve working for a long time, it is easy for the anterior leaflet and the posterior leaflet of the valve to fail to close or fully open, which will affect the blood circulation, lead to insufficient blood supply, and cause harm to human health. Usually, an artificial heart valve is placed surgically to reduce regurgitation and improve blood supply to the heart. However, the current mitral prosthetic heart valve will occupy part of the left ventricular outflow tract space after the anterior leaflet of the valve stent is implanted, causing the...
