An interatrial shunting device including a tube and an anchoring assembly. The tube defines a first end opposite a second end, and a tube wall extending to and between the first and second ends. The tube wall is a solid body and defines a lumen of the tube, with the lumen being open at the first and second ends. The anchoring assembly is carried by the tube and is configured to secure the interatrial shunting device to a native atrial septum. The solid wall tube prevents tissue overgrowth across the atrial septum, and can have minimal exposure of the device in the left atrium to minimize stroke and other risks. In some examples, the anchoring assembly is configured to be self-transitionable from a delivery state to a deployed state.
