Octogenarian Atrial Fibrillation Ablation with New NavX EnSite “Live View” Tool

Abstract

Background. Atrial Fibrillation ablation in older patients represents a challenge to be addressed to ensure the improvement of the quality of life and survival of these patients. New mapping system tools can help to treat older patients because of its ability to simplify and reduce procedural risks. The new NavX EnSite “Live view” tool allows dynamic “beat to beat” activation and voltage mapping visualization in order to instantly recognize vein disconnection and minimize RF deliveries. Methods. An 81-year old patient with paroxysmal AF and well-documented firing focus trigger underwent pulmonary veins isolation using NavX EnSite Precision, HD Grid multipolar catheter, and the new “Live view” tool. Results. All pulmonary veins were successfully isolated with no procedural complications. “Live view” tool allows to perform shorter and safer procedure (total procedural time: 90 minutes, left atrium dwell time: 60 minutes, total RF delivery number: 78). Conclusion. “Live view tool” allows dynamic activation and voltage mapping in order to perform a safe and tailored approach to ablation, especially in older patients.
