A system and method for restoring (e.g., replacing) a defective heart valve of a patient. A delivery system (44) is manipulated to percutaneously deliver and implant a stented prosthetic heart valve (20) to a native heart valve. A post-dilatation balloon (50) is percutaneously delivered to the implantation site, and a compliant segment (60) thereof is arranged within a region of the implanted prosthesis (20). The balloon (50) is inflated such that the compliant segment (60) expands and contacts the prosthesis (20), expanding a remodeling region of the prosthesis to a remodeled state. With these and related techniques, remodeling of an implanted, stented prosthetic heart valve to better match the native valve shape is possible, providing many benefits such as reducing the risk of paravalvular leaks.
