摘要：
Systems and methods of delivering and deploying a stented prosthetic heart valve having a wrap that is automatically deployed to prevent or mitigate paravalvular leakage. In various embodiments, during transcatheter delivery of the stented prosthetic heart valve, the wrap is extends beyond a stent frame of the stented prosthetic heart valve so that the profile of the stented prosthetic heart valve is not increased during delivery. The disclosed embodiments are arranged and configured so that upon expansion of a stent frame of the stented prosthetic heart valve, a plurality of elongated members automatically pull the wrap distally into a deployed arrangement.
