Atrial Fibrillation Ablation Guided with Electroanatomical Mapping System: A One year Follow up

---

Aim AF is the most common arrhythmia in clinical practice and associated with an increased long-term risk of stroke, heart failure, and all-cause mortality. Catheter ablation of AF is relatively new modality to convert A F to sinus rhythm. This study was aimed to elaborate efficacy of catheter ablation in mixed type of AF.
Methods Thirty patients (age of 52 ± 8 yo) comprised of 19 paroxysmal and 11 chronic AF underwent radio frequency catheter ablation guided by electroanatomical CARTO™ mapping system. We used step wise ablation approach with circumferential pulmonary vein isolation (PVI) as a cornerstone. Additional ablation comprised ofroofline, mitral isthmus line, complex fractionated atrial electrogram (CFAE), septal line and coronary sinus ablation was done respectively if indicated. All patients were followed up to I year for AF recurrence.
Results c!ircumferential PVl was successfully performed in all patients but one. Average follow up period was 11.5 months. More than 80% of all patients remain in sinus rhythm at the end of follow period which 62% of them were free from any anti-arrhythmic drug. No major complication in all patients series.
Conclusion Radiofrequency ablation guided with electroanatornical mapping is effective and safe in mixed type of AF. (Med J Indone s 2009; 19: 172-8)
