The present invention relates to a minimally invasive method of performing annuloplasty. According to one aspect of the present invention, a method for performing annuloplasty includes accessing a left ventricle of a heart to provide a discrete plication element (905) to the left ventricle, and engaging the plication element to tissue near a mitral valve (916) of the heart. Engaging the plication element (905) includes causing the plication element to gather a portion of the tissue to create a plication. In one embodiment, accesing the left ventricle of the heart to provide the plication element (905) includes accessing the left ventricle of the heart using a catheter arrangement.

L'invention concerne un procédé avec effraction minimale de réalisation d'une annuloplastie. Selon un aspect de l'invention, un procédé de réalisation d'une annuloplastie consiste à accéder à un ventricule gauche du coeur afin de lui fournir un élément de plication discret, et accoupler l'élément de plication aux tissus situés à proximité d'une valvule mitrale du coeur. Le couplage de l'élément de plication consiste à entraîner ce dernier à assembler une portion de tissu afin de créer une plication. Dans un autre mode de réalisation, le procédé consiste à accéder au ventricule gauche du coeur afin de lui fournir l'élément de plication, l'accès au ventricule gauche s'effectuant au moyen d'un système de cathéter.
