title: [Phonomechanograms of patients with the Bjork aortic valve prosthesis].
abstract: A survey, with consecutive phonocardiograms, of the function of 75 Björk aortic valve prostheses has enabled us to examine the basic components of the opening and closure sounds of this type of replacement; these are usually made up of multiple components in varying combinations. This diversity underlies the importance of an early postoperative recording to act as a baseline. In addition, 2 cases of malfunction presented with only the classical phonocardiographic changes.
