Even though your valve may be working fine after your surgery, there is a small risk that over time the valve may not function correctly. Aortic valve failure after aortic valve replacement occurs in less than 1 out of 100 patients.
Aortic valve failure after aortic valve replacement may be caused by a clot forming on the valve, preventing it from opening and closing properly. The replacement aortic valve may develop a leak around the sutures that hold it in place. This can be the result of the valve tissue weakening or due to an infection. Again, this occurs rarely. Further tests will most likely be done and another surgery can be performed to replace the valve.
