Atrial Strain Analysis Predicts Atrial Arrhythmia Recurrence Following Cavotricuspid Isthmus Ablation of Typical Atrial Flutter
2025
Overview
Background: This study aimed to evaluate the effectiveness of right and left atrial strain reservoir (RASr and LASr) in predicting the recurrence of atrial arrhythmias (AAs) following cavotricuspid isthmus ablation (CTIA) for typical atrial flutter (AFL). Methods: We retrospectively enrolled consecutive patients with AFL who had undergone CTIA. Transthoracic echocardiography was conducted within one month before the procedure, and atrial two-dimensional speckle tracking analysis was performed offline. Results: Sixty-two subjects were evaluated (mean age 64.8 ± 13.2 years, 29% females). At a median follow-up of 12.1 months, AA recurrence occurred in 21 subjects (33.8%). The study endpoint occurred mainly among females (p = 0.021) and patients with lower RASr and LASr values (both p < 0.001). In Cox regression analysis, RASr and LASr remained independent predictors of AA recurrence (p = 0.02 and p = 0.03, respectively). In ROC curve analysis, RASr and LASr showed a similar and satisfactory ability to predict AA recurrence with optimal cut-off values of 16.8% and 17.7%, respectively. In survival analysis, RASr > 16.8% and LASr > 17.7% were associated with significantly higher freedom from AAs during follow-up (log rank p = 0.001 and p = 0.002, respectively). Conclusions: The results of this study suggest that pre-CTIA atrial speckle tracking analysis may aid in identifying AFL patients at an increased risk of AA recurrence, allowing for more frequent follow-up visits and extended antiarrhythmic therapy.
