Patients with pulmonary valve stenosis have mild symptoms and generally do not require treatment. Surgery is the mainstay of treatment when symptoms are severe. 1. Percutaneous balloon pulmonary valvuloplasty: the method of choice for the treatment of pulmonary stenosis, with fewer complications. It is mainly used for simple pulmonary valve stenosis, patients with syncope angina, etc. 2. Direct cardiac surgery: the body circulation is established through a median sternal incision, and the heart stops beating. This type of surgery is mainly suitable for patients with obvious symptoms in moderate or severe cases. 3. Transthoracic pulmonary valve balloon dilatation: The procedure is performed under esophageal ultrasound guidance through a second rib incision in the left chest and is mainly used for younger, lighter patients. Patients diagnosed with pulmonary valve stenosis are advised to go to the hospital in time for treatment under the guidance of a doctor.
