Patients with pulmonary stenosis, if detected and treated in time, have an unaffected life expectancy; if the patient’s cardiorespiratory function has declined before surgery and his or her physical condition is poor, his or her life expectancy may be in the 50’s or 60’s. The exact situation depends on the severity of the pulmonary stenosis and the patient’s own physical condition. This depends on the severity of the pulmonary stenosis and the patient’s own physical condition. If the patient finds pulmonary stenosis in time and has minimally invasive surgery, balloon dilatation, valve replacement, etc. for treatment. And the patient’s physical condition is good, and there is no serious underlying disease, cardiopulmonary function is very good, this situation will not affect the life expectancy. However, if when the surgery is done, there are already obvious signs of decreased cardiopulmonary function, plus the patient’s physical condition is relatively poor. Even if the surgery is done, it can only alleviate the development of the disease and improve the quality of life, and the life expectancy will naturally not reach the natural life expectancy. May be fifty or sixty years old will have serious complications and die. Therefore, patients should go to the hospital for examination and receive treatment in time to avoid missing the best time.
