Title (EN) DEVICES AND METHODS FOR MAPPING CARDIAC TISSUE
(FR) DISPOSITIFS ET PROCÉDÉS DE CARTOGRAPHIE DE TISSU CARDIAQUE
Abstract:
(EN) The present disclosure relates to systems and methods for generating three-dimensional tissue maps, and particularly fibrosis maps of cardiac tissue. An intravascular device includes an elongated member and a distal tip. An imaging assembly is integrated with the elongated member to enable imaging of the microstructure of tissue near the distal tip. One or more navigation electrodes are positioned at or near the distal tip. Electrical mapping and/or ablation assemblies may also be integrated with the device. Images may be characterized according to a level of fibrosis and, using the corresponding determined locations of the images, a three-dimensional map showing areas of differential fibrosis may be generated. Electrical mapping data may also be integrated with the fibrosis map to generate a composite fibrosis and voltage map.
(FR) La présente invention concerne des systèmes et des procédés pour générer des cartes de tissu tridimensionnelles, et en particulier des cartes de fibrose de tissu cardiaque. Un dispositif intravasculaire comprend un élément allongé et une pointe distale. Un ensemble imagerie est intégré à l'élément allongé pour permettre l'imagerie de la microstructure de tissu à proximité de la pointe distale. Une ou plusieurs électrodes de navigation sont positionnées au niveau ou à proximité de la pointe distale. Des ensembles cartographie et/ou ablation électriques peuvent également être intégrés au dispositif. Des images peuvent être caractérisées en fonction d'un niveau de fibrose et, à l'aide des emplacements déterminés correspondants des images, une carte tridimensionnelle montrant des zones de fibrose différentielle peut être générée. Des données de cartographie électrique peuvent également être intégrées à la carte de fibrose pour générer une carte composite de fibrose et de tension.
