Description

The CNA-FWRD Registry is an international prospective observational multicenter registry of patients with symptomatic vasovagal syncope and bradyarrhythmias managed under routine care by medical therapy and radiofrequency catheter ablation of ganglionated plexi or permanent pacemaker implantation. Major inclusion criteria for enrollment are history of VVS or symptomatic bradyarrhythmia, age < 60 years, and evaluation by a physician and discussion about potential candidacy for radiofrequency cardioneuroablation or permanent pacemaker implantation for medically refractory symptoms.

For analysis purposes, patients awaiting the intervention will remain in the "control group" and will cross-over to the "procedural group" after successful completion of radiofrequency cardioneuroablation procedure. The follow-up for the procedure group will start at completion of CNA procedure, but patients who eventually do not get the procedure will stay in the control group until the end of the study, with similar follow-up performed as for the patients undergoing RFCA procedure. If a patient in the control group undergoes permanent pacemaker placement, then the day after the procedure the patient will be removed from the control group for follow up.
