Today, multiple terminologies used to describe mitral pathology. Terms such as prolapse,
flail, partial flail, redundant, overshooting, stretching, elongation, floppy, billowing,
ballooning, Barlow, dysplasia, myxoid, and myxomatous, for example, have different
meanings for different specialists. The confusion comes first from the fact that several of
these terms are synonyms. For example, flail leaflet, overshooting leaflet and leaflet prolapse
are synonyms. Other synonyms are Barlow, billowing, ballooning, myxomatous valve, and
mitral valve prolapse.
