Abstract
Embodiments hereof relate to a transcatheter valve prosthesis including a tubular fabric body, a first or inflow tubular scaffold attached to a first end portion of the tubular fabric body, and a second or outflow tubular scaffold attached to a second end portion of the tubular fabric body. A prosthetic valve component is disposed within and secured to an intermediate portion of the tubular fabric body that longitudinally extends between the first and second end portions of the tubular fabric body. The intermediate portion is unsupported such that neither of the first and second tubular scaffolds surrounds the intermediate portion of the tubular fabric body. The intermediate portion may include one or more windows for coronary access and may include one or more commissure reinforcement members coupled thereto to provide support for the prosthetic valve component.
