Abstract
A replacement heart valve assembly includes a stent frame including a plurality of struts defining a lattice structure with a plurality of strut junctions, an inner skirt coupled to an inner surface of the stent frame, an outer skirt coupled to an outer surface of the stent frame, and a fabric mesh wrapped around a portion of the stent frame, where the fabric mesh is positioned to reduce leak channels around the strut junctions.
