L’ablation du flutter atrial typique, de la tachycardie par réentrée intra nodale ou des voies accessoires de type faisceau de Kent est simple et réalisée dans la majorité des cas facilement en pratique courante. Occasionnellement, des difficultés pourront être rencontrées comme par exemple en cas d’anatomie particulière de l’ICT ou d’un circuit plus épicardique pour le flutter typique, lorsque l’ablation de la voie lente est inefficace au site habituel et qu’un abord gauche est nécessaire ou enfin en cas de voie accessoire proche de la VNH ou de localisation inhabituelle. Il est donc nécessaire comme pour les autres types d’ablation d’avoir une bonne connaissance anatomique et électrophysiologique ainsi qu’un protocole rigoureux, qu’il faut parfois adapter, afin d’obtenir un résultat immédiat et à long terme sûr et efficace.
