The curability of pulmonary stenosis depends on the staging and severity of pulmonary stenosis, with mild to moderate cases achieving clinical cure with aggressive treatment and complex stenosis having a poorer prognosis. Pulmonary stenosis is defined as a dynamic or fixed anatomic obstruction of the vascular system from the right ventricle to the pulmonary artery. Common modalities for the treatment of pulmonary stenosis include percutaneous balloon valvuloplasty, surgical valvotomy, and balloon angioplasty of the pulmonary arteries with or without the placement of expandable metal stents. Mild to moderate pulmonary stenosis, such as simple pulmonary valve stenosis, can be cured, especially with interventional balloon valvuloplasty, which can completely open up the adherent valves and release the stenosis, with a very good prognosis. If the stenosis is caused by secondary factors, or not simple stenosis, but complex stenosis, such as pulmonary stenosis, funnel stenosis, or combined with congenital genetic diseases, the prognosis is relatively poor. Patients are advised to go to regular hospitals in time and listen to the advice of specialized doctors.
