The interventional artificial valve comprises a support, a sheathing canal, a pulling rope and a cardiac apex anchoring piece, and the support comprises a tail end part, a connecting pulling rope, a connecting end part, a connecting end part and a connecting end part which are connected in sequence; the outer diameter of the telescopic folding part after stretching is equal to the outer diameter of the tail end part, the outer diameter of the telescopic folding part after condensation is larger than the outer diameter of the tail end part, and the telescopic folding part is in a condensation state without external force; the outer diameter of the head end part is smaller than or equal to that of the tail end part. According to the artificial valve netting structure, in the conveying process, a double-layer support form is converted into a single-layer support form to be compressed through traction and stretching, the compression space is greatly reduced, conveying convenience is improved, and the trauma risk
