A frequent type of syncope, termed vasovagal syncope is originated by intense cardioinhibition, mediated by a sudden vagal reflex, that causes transitory cardiac arrest by asystole and/or transient total atrioventricular block.[1][2] It is known as “Vaso-vagal Syncope”, “Neurocardiogenic Syncope” or “Neurally-mediated Reflex Syncope”.[3] Although many different therapies have been tried in this condition, severe and refractory cases have been treated with pacemaker implantation despite great controversies about its benefit.[4][5]
The “Cardioneuroablation” is a technique created in the nineties and patented in United States , aiming to eliminate the cardiac branch of vagal reflex in order to treat the neurocardiogenic syncope without pacemaker implantation.[6][7] It is performed without surgery, by using radiofrequency catheter ablation with one-day hospital.[citation needed]
The results up to 100 months follow-up are showing better outcome than clinical measures or pacemaker implantation with changing the tilt-test on to normal and by absence of syncope in more than 90% of patients without medications.[8][9]
