If the symptoms are obvious, surgery is recommended. As for choosing biological valve or mechanical valve, there are advantages and disadvantages, but from your age analysis, it is recommended to choose mechanical valve, because the life of mechanical valve is much longer than that of biological valve, but the disadvantage of mechanical valve is that it needs lifelong anticoagulation treatment.

In addition, valve replacement is not always necessary to treat valve diseases. If the elasticity of the valve is acceptable, you can also do aortic valvuloplasty (this is a newly developed surgical method, which does not need to open the chest, and can be operated directly through the vascular lumen with little trauma, quick recovery and no scar on the body surface after operation). But whether it is suitable for this operation depends on your own valve condition. I suggest you consult a well-known local hospital.

This operation can be performed in Beijing Anzhen and Fuwai Hospital.
