What is pulmonary stenosis?

Pulmonary ostium stenosis is a cardiovascular disease characterized by narrowing of the passage between the right ventricle and the pulmonary artery.

Pulmonary ostium stenosis occurs in infants and young children, and the prevalence rate of males is generally higher than that of females. The etiology of pulmonary ostium stenosis is unknown, and may be related to viral infection, familial inheritance, fibrous mediastinitis, arteritis, etc. When patients develop pulmonary ostium stenosis, they may experience discomfort such as dyspnea, edema of lower limbs, jugular vein distension, and hepatomegaly. If patients do not treat pulmonary ostium stenosis in time, it will cause complications such as secondary infection and heart failure.
