Аннотация
INTRODUCTION: Dual tachycardias associating paroxysmal atrial fibrillation (AF) with double-exit left aortic sinus cusp tachycardia (LASCT) are described for the first time in a patient referred for AF ablation.
CASE: Both tachycardias were successfully ablated under Carto-Merge guidance. Noteworthy, vagal denervation during AF ablation was responsible for an immediate decrease in LASCT occurrence and inducibility.
CONCLUSION: This case highlights the critical role that the autonomic nervous system plays within the cardiac arrhythmia framework.
