Abstract: A replacement heart valve implant may include an expandable framework having a plurality of frame struts defining a lattice structure, each frame strut having a thickness in a radial direction from a central longitudinal axis; and a plurality of valve leaflets coupled to the expandable framework. The plurality of frame struts defines a lower crown proximate an inflow end of the lattice structure and upper crown proximate an outflow end of the lattice structure and a plurality of stabilization arches extending downstream from the outflow end of the lattice structure. The lattice structure includes a first circumferential row of x-connectors upstream of the upper crown and a second circumferential row of x-connectors downstream of the lower crown. The thickness of at least some frame struts connecting the first and second circumferential rows of x-connectors is less than the thickness of other frame struts of the plurality of frame struts.
