Can TAVR replace a mechanical aortic valve that was put in place 13 years ago?

It might need replacing and would blood thinners still be required? Thank you.

Transcatheter aortic valve replacement is a new procedure used to implant a stented tissue valve. It can be used in the patient’s own aortic valve, if calcified, or in a previously placed aortic tissue valve replacement. It cannot be placed in a mechanical valve. If the mechanical valve needs to be replaced due to infection, obstruction, or malfunction, an open chest procedure would be required. Tissue valves do not require blood thinners in most cases.
