There is a new two-piece valve under development that allows for removal and replacement of the bioprosthetic leaflets as they wear out.
The valve is surgically implanted and contains a "docking station" that is sewn in as normal and after many years when the bovine leaflets calcify they can be removed and replaced by transapical catheter or an incision through the aorta. This allows the leaflets to be replaced as they wear out without having to remove and resew the "docking station" ring.
