Mitral-valve prolapse: Rare Disease

Mitral-valve prolapse is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). This means that Mitral-valve prolapse, or a subtype of Mitral-valve prolapse, affects less than 200,000 people in the US population.

About prevalence and incidence statistics:

The term 'prevalence' of Mitral-valve prolapse usually refers to the estimated population of people who are managing Mitral-valve prolapse at any given time. The term 'incidence' of Mitral-valve prolapse refers to the annual diagnosis rate, or the number of new cases of Mitral-valve prolapse diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
