Abrégé
(EN) 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.
(FR) La présente invention concerne un système et un procédé permettant de restaurer (par ex., remplacer) une valvule cardiaque défectueuse d'un patient. Un système d'administration (44) est manipulé pour administrer et implanter de façon percutanée une endoprothèse de valvule cardiaque (20) sur une valvule cardiaque native. Un ballonnet post-dilatation (50) est introduit par voie percutanée jusqu'au site d'implantation, et un segment souple (60) de celui-ci est disposé au sein d'une région de la prothèse implantée (20). Le ballonnet (50) est gonflé de façon à ce que le segment souple (60) se dilate et entre en contact avec la prothèse (20), faisant passer une région de remodelage de la prothèse à un état remodelé. Avec ces techniques et d'autres techniques apparentées, le remodelage d'une endoprothèse de valvule cardiaque implantée pour mieux correspondre à la forme de la valvule native est possible, apportant de nombreux avantages, comme la réduction du risque de fuites paravalvulaires.
