The present application provides an implantation method of an artificial heart valve. The implantation method can include forming an incision in the left chest to expose the ventricle; advancing a guide wire kept away from chordae tendineaes through the atrium into the ventricle; advancing a guide wire catcher into the ventricle from the incision to pull out the distal end of the guide wire from the ventricle; and advancing the artificial heart valve into the ventricle from the distal end of the guide wire with a valve deliverer, and placing the artificial heart valve at a primary valve between the ventricle and the atrium along the guide wire. The artificial heart valve may avoid the chordae tendineaes in the heart system through the guide wire track during implantation.

Implantation method of artificial heart valve

An artificial heart valve stent including: a tubular stent body having an inflow side end and an outflow side end, the inflow side end and the outflow side end being opposite to each other; an inflow side skirt surrounding the external wall of the stent body; and an outflow side skirt surrounding the external wall of the stent body. In a spread state, free ends of the inflow side skirt and the outflow side skirt extend toward the inflow side end; and the inflow side skirt cooperates with the outflow side skirt to clamp heart valve tissues. The artificial heart valve stent can be steadily arranged on heart valve tissues, prolong the service life of an artificial heart valve and reduce the risk of another artificial heart valve replacement for the patient.
