Description
Summary:Investigation and catheter ablation of cardiac arrhythmias are currently still based on optimal knowledge of arrhythmia mechanisms in relation to the cardiac anatomy involved, in order to target their crucial components. Currently, most complex arrhythmias are investigated using three-dimensional electroanatomical navigation systems, because these are felt to optimally integrate both the anatomical and electrophysiological features of a given arrhythmia in a given patient. In this article, we review the technical background of available three-dimensional electroanatomical navigation systems, and their potential use in complex ablations. L’exploration et l’ablation des arythmies cardiaques est basée sur une connaissance optimale du mécanisme de l’arythmie en relation avec l’anatomie concernée, de manière à cibler les composants critiques de celles ci. Actuellement, la plupart des arythmies complexes sont explorées avec des systèmes de navigation électro-anatomique en 3 dimensions (3D), car ceux-ci sont censés intégrer de manière optimale les éléments à la fois anatomiques et électro-physiologiques d’une arythmie donnée chez un patient donné. Dans cet article, sont rappelés les bases techniques des système 3D actuellement disponibles et les principes de leur utilisation potentielle dans les ablations complexes.
