[Sudden cardiac death in mitral valve prolapse syndrome?].

Primary mitral valve prolapse is considered a rare cause of sudden cardiac death. Close to 100 cases are documented worldwide. The cause of death seems to be cardiac arrhythmia, so postmortal diagnosis is difficult and depends on severe changes of the mitral leaflets and--sometimes--on anamnesis. Three postmortem cases are presented, where a sudden cardiac death apparently was caused by mitral valve prolapse or its complications.
