Abstract
The present application relates to a cardiac valve prosthesis and a stent thereof. The stent comprises an inflow channel, an outflow channel, and a transitional area between the inflow channel and the outflow channel along an axial direction; the outflow channel comprises a cyclic structure and at least two convex structures extending along the axial direction; the at least two convex structures are respectively connected to the end of the cyclic structure distant from the transitional area; a restricted vacant area is formed between adjacent convex structures. The cardiac valve prosthesis and the stent thereof are not only suitable for multiple types of valve replacement, risks of injuries and operation costs are reduced for patients, and the influence of the stent to cardiac functions is minimized.
