Abstract: A balloon expandable interventional valve stent has a stent main body (1), leaflets and a wing-spreading skirt (2). The wing-spreading skirt (2) is arranged outside an outflow channel (4), and several round holes (8) are evenly arranged at the edge of the wing-spreading skirt (2) close to the outflow channel (4) A pulling suture (5) is connected to the wing-spreading skirt (2). When the balloon (7) is expanded and spread, the pulling suture (5) connected to the skirt on an inflow channel (3) side is gradually tightened in the circumferential direction under the effect of the expansion force of the balloon (7), so that the wing-spreading skirt (2) is folded in the axial direction of the stent to the outside of the inflow channel (3) to form portions protruding outwards in the radial direction of the stent main body (1), so as to cover or occlude a paravalvular leak.
