![]() Strategies to prevent incident AFL using these measures after index ablation warrant further investigation.Ĭopyright © 2019 Elsevier Inc. In conclusion, noninvasive measures of right and left atrial remodeling are strongly associated with incident AFL after AF ablation. We sought to characterize patients who develop acute SND (ASND) during. Ablation may result in injury to the sinus node complex or its blood supply resulting in sinus arrest and need for temporary pacing. In the multivariable Cox regression analysis, only right atrial volume index (hazard ratio 1.25 per 10 ml/m 2, confidence interval 95% 1.10 to 1.42) was associated with incident typical AFL whereas persistent AF (HR 1.59, CI 95% 1.06 to 2.40), linear lesions (HR 1.58, CI 95% 1.02 to 2.46) and left atrial volume index (HR 1.17 per 10 ml/m 2, CI 95% 1.07 to 1.27) were associated with incident atypical AFL. Background: Many patients with atrial fibrillation (AF) or atrial flutter (Aflutter) have concomitant sinus node dysfunction (SND). Of these, 17 had typical AFL, 98 had atypical AFL, and 7 patients had both circuits. During a median follow-up of 845 days (interquartile range 389 to 1,597 days), 122 (20.1%) patients developed AFL. A total of 607 patients were included in the final cohort (age 59.2 ± 10.6 years, 76.0% men, 58.7% paroxysmal AF). Atrial volumes were measured using three-dimensional cardiac computed tomography or magnetic resonance imaging. Patients with missing follow-up data, history of AFL ablation, and those with undocumented AFL were excluded. The retrospective cohort consisted of 1,029 patients that underwent initial radiofrequency AF ablation from May 2005 to December 2013 at a single academic center. The incidence of arrhythmia recurrences after AF ablation was analyzed during long-term follow-up using repetitive 7-day ECG recording. Of the patients with AF or AFL, 20 and 5, respectively, also had episodes of atrial tachycardia and supraventricular tachyarrhythmia. Of the patients with ATA, 59 had atrial fibrillation (AF), 14 had atrial flutter (AFL), and 27 had both AF and AFL. 2 6 However, prior studies have suggested that the presence of AF leads to more AF because of a variety of proposed mechanisms, including structural 7 9 and. Results ATA occurred in 86 patients (43) after the Maze procedure. We aimed to define (1) the incidence of AFL and (2) the clinical factors associated with cavo-tricuspid isthmus dependent (typical) and atypical AFL, after AF ablation. There is mixed evidence in the literature regarding the prognostic values of early recurrence of atrial arrhythmias within the first 6 to 12 weeks post-pulmonary vein (PV) ablation. ![]() ![]() Atrial flutter (AFL) is a common form of arrhythmia recurrence after atrial fibrillation (AF) ablation.
