The effect of patient characteristics to the acute procedural success and long term outcome of atrial tachycardia and atrial flutter cases undergoing catheter ablation

Objective: In the present study we aimed to demonstrate clinical characteristics, predictors of procedural success and long term recurrence atrial tachyarrhythmia patients undergoing catheter ablation (CA). Patients Methods: Consecutive who had undergone CA due an in a single centre arrhythmia unit between 2012 – 2020 were screened. Predictors analysed by logistic regression. Results: Study population consisted 299 consecutive (95 [31.8 %] tachycardia, 204 [68.2 flutter cases);163 ( 54.5 % ) male; median age was 54 IQR; 42-64). Median follow up 330 (IQR; 90 810) days. Atrial older more co-morbidities. Acute rate 82.1 vs. 77.0 (p= 0.313) 9.3 21.6 (p=0.022) tachycardia (AT) (AFL) cases respectively. History valvular or congenital heart disease surgery, left atrium diameter found be independent failed ablation, post-procedural fibrillation. Conclusion: Age, diameter, surgery are for acute success, fibrillation AT AFL undergo ablation.
