The prosthetic cardiac valve (1) consists of two or three supple cusps (2) in combination with a tubular stent-type support (3). The cusps can be attached to the support by suturing, thermal adhesion or molding, and they can be made separately from one another or in one piece with folds. The support has a peripheral suturing cushion (4) for holding it in place after fitting.
