A stent device with skirt folds and a processing method thereof, a skirt folding method, and a heart valve. The stent device comprises a stent () and a flexible skirt (), the skirt () having an expanded state, in which the skirt is axially extended and surrounds the stent () before release thereof, and a folded state, in which the skirt is driven by the deformation caused when the stent () is released, collapses and folds axially along the released stent () so as to form an annular peripheral leakage-blocking portion. The peripheral leakage prevention technology enables an interventional stent to fit to the inner wall of a vessel more snugly, such that the stent does not easily move and is more stable, thereby being suitable for more people, reducing additional risks of surgery and preventing complications such as peripheral leakage and thrombus. The present disclosure can provide better blood dynamics, increase the crawling capability of endothelial cells of a host, reduce the probability of occurrence of endocarditis, and restore a normal blood supply functionality of vessels.
