A Retrospective Cohort Study on Predictors for Rehospitalizations With Recurrence of Atrial Fibrillation Post-Catheter Ablation for Atrial Fibrillation

Abstract

Atrial fibrillation (AF) is the most common cardiac arrhythmia and is increasing in prevalence due to an aging population. Although medications for rhythm and rate control remain the first-line treatment options for many patients, difficulties can include arrhythmia relapse and drug side effects. Catheter ablation or radiofrequency is an alternative treatment modality that can isolate where ectopic arrhythmic sites originate. Several previous studies have examined post-ablation complications and hospitalization rates for arrhythmia recurrence. However, many of these studies used patient data from before 2015. We examined the following data using recent records: pre-procedural patient characteristics, rates of post-procedural hospitalizations with documented recurrence of AF, and patient risk factors associated with these recurrences.

Low voltage in small left atrium in patients with persistent atrial fibrillation: left atrium diameter alone is not always a predictor of prognosis

“…The ablation of PeAF in elderly women showed the worst outcomes, which indicates that women may require intervention during the early stage of AF (12)(13)(14)(15)To prevent failure of ablation and achieve better outcomes, we recommend intensive screening for AF and aggressive intervention for paroxysmal AF in elderly women.…”
