The diagnosis of pulmonary valve stenosis can be achieved via echocardiogram, as well as a
variety of other means among them are: ultrasound, in which images of the heart chambers in utero where
the tricuspid valve has thickening (or due to Fallot's tetralogy, Noonan's syndrome, and other congenital defects)
and in infancy auscultation of the heart can reveal identification of a murmur.
Some other conditions to contemplate (in diagnosis of pulmonic valvular stenosis) are the following:
- Infundibular Stenosis,
- Supravalvular Pulmonary Stenosis,
- Dysplastic Pulmonic Valve Stenosis.
