![]() Predictors and Incidence of Atrial Flutter After Catheter Ablation of Atrial Fibrillation. Predictors of early and late left atrial tachycardia and left atrial flutter after catheter ablation of atrial fibrillation: Long-term follow-up. Wójcik M, Berkowitsch A, Zaltsberg S, et al. European Heart Journal-Cardiovascular Imaging. Recommendations for cardiac chamber quantification by echocardiography in adults: an update from the American Society of Echocardiography and the European Association of Cardiovascular Imaging. ![]() Circulation: Arrhythmia and Electrophysiology. Updated worldwide survey on the methods, efficacy, and safety of catheter ablation for human atrial fibrillation. Type II (atypical) atrial flutter follows a significantly different re-entry pathway to type I flutter, and is typically faster, usually 340350 beats/minute. 2017 HRS/EHRA/ECAS/APHRS/SOLAECE expert consensus statement on catheter and surgical ablation of atrial fibrillation. Journal of Cardiovascular Electrophysiology Published by Wiley Periodicals LLC.Ĭalkins H, Hindricks G, Cappato R, et al. The success rate of first repeat ablation is significantly higher among patients with recurrent atypical AFL as compared to recurrent AF after index AF ablation.Ītrial fibrillation atypical atrial flutter left atrial volume index perimitral atrial flutter radiofrequency ablation roof dependent atrial flutter. Patients developing atypical AFL after index AF ablation have greater LA dimensions than patients with recurrent AF. In our series, roof-dependent flutter is the most common form of atypical atrial flutter post AF ablation. Arrhythmia-free survival at one year was significantly higher in the recurrent atypical AFL compared to the recurrent AF cohort (75.5 vs. ![]() Major complications at repeat ablation occurred in 0.9% of the total cohort. Atypical AFLs were roof-dependent in 35.6% and peri-mitral in 23.8% of cases. Atypical AFL patients were more likely to have had index radiofrequency (RF) ablation (as opposed to cryoballoon) than recurrent AF patients (98% vs. 03) compared to AF patients at repeat ablation. The atypical AFL cohort had significantly higher LA diameters (4.6 vs. The mean age was 63.7 ± 10.7 years, and 72.6% of patients were men. Among these 336 patients, 102 underwent a repeat ablation procedure for atypical AFL and 234 underwent a repeat ablation procedure for recurrent AF. The demographics, clinical history, procedural data, complications, and 1-year arrhythmia-free survival rates were recorded for each subject after the first repeat ablation.Ī total of 336 patients were included in our study. We studied consecutive patients who underwent a repeat left atrial (LA) ablation procedure for either recurrent AF or atypical AFL, at least 3 months after index AF ablation, between January 2012 and July 2019. But over time, atrial flutter often returns since cardioversion alone does not correct the underlying causes of an abnormal heart rhythm.Data related to electrophysiologic characteristics of atypical atrial flutter (AFL) following atrial fibrillation (AF) ablation and its prognostic value on repeat ablation success are limited. This commonly will restore your normal heart rhythm.
