Whether aortic valve calcification is serious or not should be judged according to the patient’s symptoms and cardiac ultrasound, as follows: 1, causing impaired valve function, such as causing severe stenosis, or incomplete closure, is a more serious situation; 2, if there is no effect on hemodynamics, not causing significant stenosis or incomplete closure, observation is sufficient and no treatment is needed. With the development of aortic valve calcification, if it leads to stenosis of the valve, especially moderate or severe stenosis, it can lead to heart failure and even sudden death. The clinical manifestations are angina pectoris, and the most serious is that it can lead to sudden death. This condition should be treated, usually surgically, either by open-heart surgery to replace the valve. There are now 10-20 large hospitals in China that have carried out TAVR surgery, which can be performed through the blood vessels for replacement.
