The life expectancy of patients after aortic valve replacement is affected by a variety of factors such as the severity of the disease, the timing of treatment, and whether or not there is a combination of complications, and it is not possible to definitively determine the expected survival period. 1. For patients with early aortic valve lesions, if aortic valve replacement is performed before the emergence of serious complications such as heart failure, and if the patient recovers well after the operation, and if there are no obvious symptoms of panic, shortness of breath, chest tightness and chest pain in daily activities, then the patient’s prognosis is better, and the impact on the patient’s long-term survival is smaller. 2. For patients who have developed serious complications such as heart failure, the timing of surgery is late, and even if aortic valve replacement is performed, symptoms such as panic, shortness of breath, chest tightness and fatigue may still be present after surgery, and this type of patient has a relatively poor prognosis, which also has an impact on the patient’s long-term survival. For patients who need aortic valve replacement, it is recommended that they be treated as early as possible under the guidance of their doctors to avoid serious complications that may affect their long-term survival.
