[Barlow's disease with arrhythmic phenotype: a case report].

Barlow disease represents the extreme form of the degenerative mitral valve spectrum described by Carpentier. The myxoid degeneration of the mitral valve may result in a billowing leaflet or in a prolapse and myxomatous degeneration of the mitral leaflets. There are increasing evidences of the association between Barlow disease and sudden cardiac death.
