Main Article Content

Abstract

Aims: This study evaluated the initial results of radiofrequency catheter ablation of focal atrial tachycardia under the guidance of 3D electro-anatomical mapping system. Method and Results: This study included 18 consecutive patients diagnosed with focal atrial tachycardia who underwent RF ablation at the Vietnam National Heart Institute (Bach Mai hospital) from August 2023 to December 2023. Ensite Precision Mapping System (St. Medical, USA) was used to reconstruct the atrium’s electro-anatomical model during the tachycardia. Paroxysmal and incessant AT ratios were 68.9% and 31.1%, respectively. In 2 patients (11.1%), incessant ATs caused tachycardia-induced cardiomyopathy. A total of 20 ATs were ablated with an acute and after 3 month follow up success rate of 100%. There were no significant procdure-related complications. 17 ATs (85%) originated from the right atrium, and 3 ATs (15%) originated from the left atrium and non-coronary cusp. The mean mapping time was 25.5 ± 16.8 minutes, and the mean fluoroscopy time was 6.4 ±6.2 minutes. Conclusion: 3D mapping system facilitates the diagnosis and ablation of focal atrial tachycardia, reduces radiation exposure for healthcare workers and patients.
