Follow up
Immediate complications of the procedure were assessed, namely vascular access complication, pericardial effusion, stroke or arrhythmias. All patients were scheduled for presential follow-up at 30 days with ECG with measurement of HR and PQ interval. At the six-month visit and every six months afterwards a 24-hour Holter monitoring was performed. Three patients had an implantable cardiac monitor (ICM) implanted (for which two were implanted at the same admission of the ablation procedure, at physician discretion). Antiarrhythmic drugs were maintained for at least 3 months in patients with AF and ceased afterwards if no recurrences were detected.
