The severity of pulmonary stenosis depends on the degree of stenosis and can be categorized as mild stenosis and moderate and severe stenosis. Severe pulmonary stenosis is more serious.
1. Mild pulmonary stenosis: the pressure difference across the valves does not exceed 40mmHg, only heart murmurs can be heard, no surgical treatment is needed, and attention must be paid to preventing infective endocarditis. Through treatment, normal growth and development can be achieved without affecting daily life.
2. Moderate pulmonary stenosis: transvalvular pressure difference is more than 40mmHg, but not more than 100mmHg, and the size of the orifice is 1.0~1.5cm. Surgery should be performed after the age of 20 years, otherwise it will aggravate with the growth of age.
3. severe pulmonary stenosis: transvalvular pressure difference of more than 100mmHg, the examination found that the pulmonary valve orifice is less than 1cm, at this time is more serious, the onset of cyanosis, and the symptoms of right heart failure is serious, should be immediately surgical incision of the valve, surgical treatment can be satisfied with the results.
Patients with pulmonary stenosis should also actively prevent the occurrence of complications, especially in patients with severe stenosis, early heart failure, early detection, early treatment. Follow the doctor’s instructions standardized treatment.
