The methods, devices, and systems are provided for performing endovascular repair of atrioventricular and other cardiac valves in the heart. Regurgitation of an atrioventricular valve, particularly a mitral valve, can be repaired by modifying a tissue structure selected from the valve leaflets, the valve annulus, the valve chordae, and the papillary muscles. These structures may be modified by suturing, stapling, snaring, or shortening, using interventional tools (30, 36, 56) which are introduced to a heart chamber. Preferably, the tissue structures will be temporarily grasped and held into position prior to permanent attachment.

L'invention porte sur des méthodes, des dispositifs et des systèmes permettant de réaliser une réparation endovasculaire des valvules atrioventriculaires et autres valvules cardiaques. La régurgitation d'une valvule atrioventriculaire, en particulier d'une valvule mitrale, peut se réparer en modifiant une structure tissulaire choisie parmi les suivantes : valves de valvules, anneau de la valvule, cordes de la valvule et muscles papillaires. Ces structures peuvent être modifiées par suture, agrafage, récupération ou raccourcissement à l'aide d'outils permettant une intervention (30, 36, 56), lesquels sont insérés dans une cavité du cour. De préférence, les structures tissulaires seront temporairement saisies et maintenues en position avant leur fixation permanente.
