Pulmonary Stenosis

Types of Pulmonary Stenosis?: Pulmonary stenosis? can be classified into three main types:

1. Valvular Pulmonary Stenosis?: This occurs when the pulmonary valve, which separates the right ventricle from the pulmonary artery, is narrow.
2. Subvalvular Pulmonary Stenosis?: It happens when there is a narrowing just below the pulmonary valve.
3. Supravalvular Pulmonary Stenosis?: This is a rare type where the narrowing occurs in the pulmonary artery above the valve.
