1,833 Possible Causes for Mitral Valve Prolapse, Muscle Biopsy showing Variation In Fiber Size, Onset between 6 and 14 Years

  • Muscular Dystrophy

    Muscle biopsies of the proband showed large variations in muscle fiber size, necrotic and regenerating fibers and an increase in endomysial collagen tissue.[ncbi.nlm.nih.gov] variation in muscle fiber size not segregated by motor unit.[merckmanuals.com] Serum creatine kinase was increased and muscle biopsy showed moderate fiber size variation, internalized nuclei, and absence of emerin staining.[web.archive.org]

  • Myotonic Dystrophy

    Mitral valve prolapse in 20%. First-degree AV block is common.

Type one fibers may predominate.[ncbi.nlm.nih.gov]
