Brief Summary

Pulmonary vein isolation (PVI) is a cornerstone for catheter ablation of atrial fibrillation (AF), however, exact mechanisms of PVI efficacy remain debatable. It has been postulated that in patients with increased vagal tone AF can be treated by attenuation of parasympathetic drive to the heart using cardioneuroablation (CNA) by means of radiofrequency (RF) of the ganglionated plexi, however, data in literature and guidelines are lacking. The objective of this study is to examine the mid-term efficacy of RF-CNA targeting the right anterior ganglionated plexus (RAGP) in management of AF using right-atrial approach only.

Sampling MethodProbability Sample
Study Population

Consecutive patients with paroxysmal AF who were scheduled for ablation of AF and in whom clinical parameters such as sinus bradycardia and AF paroxysms occurring during rest, night or after meals, suggested vagally-mediated AF, were considered for the study.

You may qualify if:

  • Paroxysmal atrial fibrillation
  • Deceleration capacity \>7ms

You may not qualify if:

  • Permanent AF lasting more than one year or persistent AF lasting more than 7 days
  • AF secondary to electrolyte imbalance, thyroid disease, alcohol abuse, or other non-heart related causes
  • Anteroposterior dimension of the left atrium in the echocardiography ≥ 5.5 cm
  • Significant valvular disease
  • Prosthetic valve
  • Heart failure New York Heart Association (NYHA) class III/IV
  • Previous AF ablation
  • History of a persistent oval opening/atrial septal defect closure
  • History of left atrial appendage closure
  • Atrial myxoma
  • Presence of a cardiac pacemaker, defibrillator or cardiac resynchronization therapy device
  • Symptomatic hypotension
  • History of pericarditis
  • Congenital heart disease
  • History of coagulation disorders
  • +10 more criteria
