Abstract

The invention relates to a heart valve which comprises a valve stent and a tying rope, wherein the valve stent comprises a main body stent, a skirt stent and a fixing part; the skirt stent and the fixing part are separately arranged on the main body stent; and the tying rope is detachably connected with the main body stent. In the operation process, after it is ensured that the fixing part is fixedly connected with heart tissue through push testing, the tying rope can be dissociated from the valve stent, and thus the risk of thrombi caused if the tying rope is retained in a left ventricle canbe avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a heart valve. Background technique [0002] Heart valve disease is a very common heart disease, among which valve damage caused by rheumatic fever is one of the most common causes. With the aging of the population, senile valvular disease and valvular disease caused by coronary heart disease and myocardial infarction are becoming more and more common. These valvular lesions not only endanger life safety and affect the quality of life, but also bring heavy burden and pressure to families and society. The human heart is divided into four chambers: the left atrium, the left ventricle, the right atrium, and the right ventricle. The two atria are connected to the two ventricles, and the two ventricles are connected to the two great arteries. Heart valves grow between the atrium and ventricle, between the ventricle and the aorta, and act as one-way valves to help blood flow in one dir...
