Key result
Radiofrequency catheter ablation for atrioventricular reciprocating tachycardia achieved an overall acute success rate of 99.3% with a low complication rate of 1.4%.
Why the study?
Radiofrequency catheter ablation is curative for paroxysmal supraventricular tachycardia, and the study aimed to evaluate single-center experience with electrophysiology procedures and radiofrequency ablation in AVRT.
Does radiofrequency ablation safely and effectively treat atrioventricular reciprocating tachycardia in a real-world setting?
Observational (n=141)
No
Does radiofrequency ablation safely and effectively treat atrioventricular reciprocating tachycardia in a real-world setting?
Radiofrequency ablation is a highly effective and safe treatment for atrioventricular reciprocating tachycardia in a real-world setting in Bangladesh, achieving a 99.3% acute success rate.
Supports RF ablation for AVRT in real-world cohorts; leaves open need for randomized trials on durability.
Background: Radiofrequency catheter ablation is a curative modality of treatment for paroxysmal supraventricular tachycardia. The aim of our study was to evaluate our experience of electrophysiology procedures and radiofrequency ablation in atrioventricular reciprocating tachycardia (AVRT). Methods: All patients undergoing cardiac electrophysiology and radiofrequency ablation procedures during the period from July, 2019 to July, 2021 at Department of Cardiology, Evercare Hospital, Dhaka were included in this study. The study analyzed 141 patients of among them 75(53.2%) patients were male and 66(46.8%) were female. Results: Patients who came with AVRT, 91 (65%) had concealed and 50 (35%) had manifested. The overall short term success rate was 99 %. There was no difference in the success rates between the younger and older patients. Complication rate is lower side of the spectrum, which is 1.4% (four patients). Conclusion: Radiofrequency ablation is a safe and successful treatment modality for patients with atrioventricular reciprocating tachycardia in this real - world study.

Bala et al. (2022) conducted an observational in Atrioventricular reciprocating tachycardia (AVRT) (n=141). Radiofrequency catheter ablation (RFA) was evaluated on Acute ablation success (absence of antegrade and/or retrograde accessory pathway conduction). Radiofrequency catheter ablation for atrioventricular reciprocating tachycardia achieved an overall acute success rate of 99.3% with a low complication rate of 1.4%.
