Prevalence and Incidence of Pulmonary valve stenosis

Pulmonary valve stenosis: Rare Disease

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

Ophanet, who are a consortium of European partners, currently defines a condition rare when if affects 1 person per 2,000. They list Pulmonary valve stenosis as a "rare disease". More information about Pulmonary valve stenosis is available from Orphanet

About prevalence and incidence statistics:

The term 'prevalence' of Pulmonary valve stenosis usually refers to the estimated population of people who are managing Pulmonary valve stenosis at any given time. The term 'incidence' of Pulmonary valve stenosis refers to the annual diagnosis rate, or the number of new cases of Pulmonary valve stenosis 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.
