Abstract

Aims: The aim was to study the preliminary result and safety of catheter ablation for AT/APCs originating from the aortic cusps at the Vietnam Heart Institute and other hospitals in Vietnam. Results: Between 2014 and 2023, 11 patients (7 women, 4 men, mean age 52.6 ± 13.6 years) with symptomatic atrial tachycardias (9 patients) or frequent atrial premature contactions (1 patient) originating from sinus of Valsalva was successfully ablated by radiofrequency energy at the Vietnam Heart Institute (9 patients), Dong Do hospital (1 patient) and Hanoi Medical University hospital (1 patient). The origin was from the non-coronary sinus in 10 patients (91%) and the left coronary sinus in 1 patient (9%). Early activation recording is the predominant method to locate the site of origin an early activation time of 25 ± 14 ms measured from the onset of the P' wave. Ablation was successful in 100% of cases immediately after the procedure and there were no cases of recurrence during the post-procedure follow-up period. Procedure time was 69.5 ± 16.8 minutes, X-ray exposure time was 11.5 ± 5.5 minutes. The ablation parameters include the target temperature achieved: 55-60 degrees Celsius with power level set from 15 to 40W. No procedure-related complications were noted. Conclusion: Ablation within the aortic sinus of Valsalva is safe and effective for the treatment of atrial arrhythmias.
