Abstract
A prosthetic heart valve includes a multi-part frame having a first annular body and an anchor component that includes a second annular body circumscribing the first annular body. The first annular body includes a plurality of struts arranged in a lattice pattern and defining a lumen. The anchor component further includes one or more ventricular anchors extending from the second annular body toward an inflow end portion of the first annular body. A fabric layer is disposed on an inner surface of the first annular body and sutured to the struts. A valve structure including three leaflets is disposed within the lumen and inlet ends of the leaflets are sutured to the fabric layer. 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 a native valve.
