The leaflet material includes a lower portion attached to the stent frame and an upper portion that includes leaflets capable of moving between an open configuration and a closed configuration. At least a portion of the leaflet material weaves through the stent frame. The transcatheter prosthetic heart valve also includes one or more reinforcement components coupled to the stent frame and/or to the leaflet material to enhance performance of the transcatheter heart valve.
