Clinical Trial Summary

The goal of this study is to compare effectiveness of cardioneuroablation of right anterior ganglionated plexus and pulmonary vein isolation in patients with enhanced vagal tone expressed as deceleration capacity >7.5ms.

Description:

Patients included into the study will be randomized to a group undergoing cardioneuroablation (CNA) of the right anterior ganglionated plexus (RAGP) or pulmonary vein isolation (PVI).

In CNA group the location of RAGP will be determined anatomically below the superior vena cava ostium near the superior-septal aspect of the right atrium. Radiofrequency (RF) applications will be delivered and will be continued until heart rate (HR) acceleration >30% is achieved or if the RF time exceeds 120s.

In the PVI group point-by-point RF isolation of all pulmonary veins will be performed.

Clinical follow-up (FU) will consist of multiple ambulatory visits combined with standard ECG readings and a 7-day Holter recording. During FU visits, a detailed history of any palpitations, episodes of atrial fibrillation (AF), and hospitalizations for cardiac arrhythmias will be collected.

Intervention

Procedure:
• Cardioneuroablation of right anterior ganglionated plexus
Right anterior ganglionated plexus will be localized using anatomical approach. Radiofrequency energy will be delivered until heart rate acceleration >30% is achieved or if radiofrequency time exceeds 120 seconds.
• Pulmonary vein isolation
Application sites near the ostia of pulmonary veins will be determined. Radiofrequency energy will be delivered using point-by-point technique. After applications, the acute PVI endpoint will be confirmed by the elimination of PV potentials and lack of capture during pacing from the ablation lines.
