[The pathology of mitral valve prolapse in dogs].

The authors present investigations of the prolapse of the mitral valves in dogs. In 18 cases there were dogs with a prolapse, in 6 dogs there was a prolapse of the tricuspid valves, and in 3 cases a prolapse of both valves was observed. In all cases prolapse occurred together with endocardiosis of the valves or as a consequence of it.
