Differential effects of ganglionic plexi ablation in apatient with neurally mediated syncope and intermittent atrioventricular block: acommentary

ABSTRACT

The treatment of functional bradyarrhythmias by means of endocardial radiofrequency (RF) catheter ablation of the autonomic nervous system began with the original publication in EP-Europace in 2005and it is known as ‘cardioneuro ablation’ (CNA).1,2 The reproducibility and good long-term results have largely been observed justifyingits rapid worldwide expansion having deserved a specific section atHeart Rhythm Society Annual Sessions in 2015 and 2016. The maingoal of CNA is the parasympathetic denervation of the heart to allowthe treatment of bradyarrhythmias symptomatic reflex (neurocardiogenicsyncope) and/or functional (sinus node dysfunction andfunctional atrioventricular (AV) block). Currently, it has been observed very good results in same types of functional brady-tachy syndrome. It is essentially based on a very specific cardiac neural distribution...
