The unit physical examination detected, aortic valve closure insufficiency, medium amount of regurgitation, left ventricular diastolic hypofunction. At present, there are not many symptoms, after the detection to the attention of a little, the activity is strong feeling gas is not enough, no treatment how to do? Whether aortic valve closure insufficiency requires valve replacement surgery, there are several issues to be clarified. First, the lesion is caused by what disease, if it is caused by connective tissue disease, surgery must be very careful, otherwise surgery is likely to occur after the unmanageable perivalvular leakage; second is whether the patient has symptoms, mainly post-activity panic shortness of breath, syncope or angina, symptoms should be operated; third is whether the ventricular function is impaired, if the ejection fraction is less than 60% or left ventricular end-diastolic diameter of more than 70mm, also If the ejection fraction is less than 60% or the left ventricular end-diastolic diameter is more than 70mm, surgery should be performed; fourth, the degree of dilatation of the ascending aorta. The information you provided does not include any of these, so I cannot determine whether surgery is needed.
