The present application relates to a method for visual identification of atrial tissue comprising the steps of visualizing a site of atrial tissue formation using a device adapted for visualizing and obtaining an image; and analyzing the image to determine the presence, location and/or distribution of atrial tissue in the site. The present application also discloses to a method for the treatment of atrial fibrillation in a patient, comprising the steps of identifying atrial tissue in a site of atrial tissue formation by introducing a device adapted for visualization into the site; and substantially ablating atrial tissue previously identified. The present application invention further discloses a method for determining the shape of an atrial tissue formation comprising the step of identifying atrial tissue site potential indicative of the shape of the atrial tissue.
La présente invention concerne un procédé d'identification visuelle d'un tissu atrial, comprenant les étapes consistant à visualiser un site de formation de tissu atrial au moyen d'un dispositif de visualisation et de collecte d'image; puis, à analyser cette image afin de déterminer la présence, l'emplacement et/ou la répartition d'un tissu atrial dans le site. La présente invention concerne également une méthode permettant de traiter la fibrillation atriale chez un patient. Cette méthode consiste à identifier un tissu atrial dans un site de formation de tissu atrial par introduction d'un dispositif conçu pour visualiser l'intérieur du site; puis, à prélever sensiblement un tissu atrial préalablement identifié. Cette invention concerne également une méthode permettant de déterminer la forme d'une formation de tissu atrial, consistant à identifier un site de tissu atrial susceptible d'indiquer la forme du tissu atrial.
