Pulmonary stenosis

The incidence rate of pulmonary stenosis is about 8% to 10% of congenital heart disease. Pulmonary stenosis is the most common pulmonary stenosis, accounting for 90%, followed by funnel stenosis. Arteriosclera and its branches are rare. But secondary or subvalvular stenosis can be secondary or subvalvular. It can exist alone or as part of other cardiac malformations, such as tetralogy of Fallot and patent foramen ovale. If the cross valve pressure difference is less than 30% mmHg, there will generally be no obvious clinical symptoms.
