Abstract
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.
