Abstract
A prosthetic heart valve for implantation at a native heart valve includes a multi-part frame. The multi-part frame includes a cylindrical main body and a ventricular anchor component surrounding the main body. The main body includes a plurality of struts arranged in a lattice pattern. The ventricular anchor component is attached to the main body only at an outflow end of the main body and extends toward an inflow end of the main body. The prosthetic valve further includes a valve structure having three leaflets made from pericardium. The multi-part frame is radially compressible for delivery within a sheath of a delivery catheter and is self-expandable for deployment within an annulus of the native valve. The main body and the ventricular anchor component are formed separately and are attached by a locking mechanism for reducing strain between the main body and the ventricular anchor component.
