[Report on a rare case of mitral valve aneurysm (author's transl)]

Authors describe the mitral valve aneurysm localised in the right half of the valve dorsal leaflet as an accidental finding during autopsy of 72-years-old man. They deal with similar cases described in literature, however they point out the difference between their own case and those referred by other authors. The terms of "parachute valve" and mitral valve prolapse (resp. the syndroma of the mitral valve prolapsus) are also discussed.
