Dual tachycardias associating double-exit left aortic sinus cusp tachycardia with paroxysmal atrial fibrillation: evidence of a link between both arrhythmias by means of the autonomic nervous system.
BACKGROUND
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.


METHODS
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.


CONCLUSIONS
This case highlights the critical role that the autonomic nervous system plays within the cardiac arrhythmia framework.
