Hello, according to the information you provided, patients' dizziness, fatigue, dizziness aggravated by fast walking and occasional blackness in front of their eyes are all related to aortic valve lesions. The indication of operation is still clear, and surgery should be performed. Valve replacement is one of the routine heart operations at present, and the operation is not difficult. The risk should be comprehensively assessed according to the patient's general condition (liver/kidney/lung/brain function), of course, mainly depending on the heart function. If the patient's liver, kidney, lung and brain functions are normal, in view of his ideal heart function at present, he should be able to tolerate surgery. As far as the patient's current age is concerned, coronary angiography is needed before operation to determine whether there is coronary artery disease, and if there is, it should be treated together during operation. For reference only! If necessary, you can contact me by phone (see doctor's clinic time at the bottom of the homepage of the website).

Yi Song, a doctor from Qilu Hospital of Shandong University, solemnly reminded me that I couldn't fully understand the illness because I couldn't see the patient in person. The above suggestions are for reference only. Please go to the hospital for specific diagnosis and treatment under the guidance of a doctor! )
