Background: Cardioneuroablation is one of the emerging therapies in vasovagal syncope. In this study, we present a simple method of cardioneuroablation performed via a rightsided approach, targeting anterior-right and right-inferior ganglionated plexi, along with procedural and follow-up data.

Methods: Patients who had underwent cardioneuroablation between March 2018 and September 2019 with vasovagal syncope in 2 clinics were enrolled in the study. All patients underwent radio-anatomically guided radiofrequency ablation targeting anterior-right ganglionated plexi and right-inferior ganglionated plexi. Syncope and symptom burden, 24-hour ambulatory electrocardiogram data at presentation, and at follow-up were assessed along with procedural data.

Results: A total of 23 patients underwent modified right-sided cardioneuroablation. Mean basal cycle length decreased significantly from 862.3 ± 174.5 ms at the beginning of the procedure 695.8 ± 152.1 ms following the final radiofrequency ablation (P < .001). Mean 24-hour ambulatory heart rate increased significantly from 66.4 ± 10.7 bpm at baseline to 80 ± 7.6 bpm at follow-up (P < .001). Only 1 patient had 1 episode of syncope following the procedure at the mean follow-up period of 10 ± 2.9 months. The same patient had recurrent presyncope.

Conclusion: The right-sided cardioneuroablation approach was found to be an effective treatment for vasovagal syncope and may be regarded as a default initial cardioneuroablation technique.
