If the valve lesion is mild, it is possible to return to normal after valve replacement surgery. However, if the valve lesions are severe and cause other complications, it is difficult for these patients to return to normal heart function even after undergoing surgery. Valve replacement surgery is mainly used to treat mitral valve stenosis and insufficiency, aortic valve stenosis and aortic valve insufficiency. If the patient’s heart valve disease is relatively mild and does not cause secondary changes such as cardiac hypertrophy or dilatation, the patient’s heart function can be restored to normal after valve replacement surgery, and the patient can live as a normal person. However, if the patient has a long history of the disease, or if the heart valve lesions are severe, causing heart dilatation, or even chronic heart failure and other symptoms. Even if these patients undergo valve replacement surgery, they will not be able to fully return to normal in the future. Therefore, if a patient’s examination reveals a heart valve disease, he or she needs to consult a doctor in time and be treated under the guidance of a professional physician.
