    Abstract: Systems, devices, and methods for shunting blood from one anatomical chamber/vessel to another anatomical chamber/vessel are described. For example, a dual frame shunt can include an anchoring frame/structure that is configured to self-expand and to anchor the shunt within an opening between two anatomical chambers/features. The shunt can also include an adjustable frame/structure disposed outside or inside of at least a portion of the anchoring frame and configured to expand/adjust to various sizes.

    Abstract: A prosthetic heart valve configured to be expanded within a native valve annulus, engage surrounding tissue, and constricted tissue inward to enhance contact between the tissue and the valve. The heart valve may have a structural valve stent with an outer constricting structure having tissue-engaging members or anchors. The constricting structure may be intrinsic or extrinsic. One intrinsic version includes a plurality of arms that are arranged to constrict inward toward a central valve portion, or a fabric structure with tissue anchors and surrounding an inner valve member may be cinched to pull the tissue inward. The anchors may engage tissue around the annulus in the atrium, or surround leaflets in the ventricle, or grasp leaflets from within.
