Prosthetic band (1), in particular for repairing a mitral valve, comprising an elongate band (2) made of a flexible material for the fixation of artificial cords, and including a plurality of separable pads (4) that are joined along the trajectory of said elongate band (2) and protrude with respect thereto, said pads (4) being separated from each other and capable of receiving such artificial cords. In this way, the proper length of the artificial cords can be established, and they can be tied without slippage of the knots with the aim of applying them during an operation for the repair of a prolapse of the mitral valve
