What is the normal pulmonary valve area?
A normal pulmonary valve area measures approximately 2 cm2 (square centimetres)
What are the types of pulmonary stenosis?
Pulmonic stenosis may be valvular, subvalvular, or supravalvular.
Describe blood flow pattern on chest radiographs?
Patients with supravalvular stenosis also typically have normal pulmonary blood flow on CXR. Patients with subvalvular, or infundibular stenosis, however, typically have tetrology of Fallot and therefore demonstrate decreased pulmonary blood flow.
