Follow up for Ablation success:
Patients were followed for a period of one year after the CBA procedure for the development of any form of atrial arrhythmias (AA). AA were confirmed on chart review by self-reported patient symptom and documented by EKG’s or any form of long-term cardiac rhythm monitoring such as a holter or event monitor. A three month blanking period was followed to allow for recurrence of AA after the initial procedure except for symptomatic patients with early recurrence requiring a repeat procedure such as an electrical cardioversion or repeat ablation.
