DR-FLASH Score Is Useful for Identifying Patients With Persistent Atrial Fibrillation Who Require Extensive Catheter Ablation Procedures.

ABSTRACT: Background Modification of arrhythmogenic substrates with extensive ablation comprising linear and/or complex fractional atrial electrogram ablation in addition to pulmonary vein isolation (PVI-plus) can theoretically reduce the recurrence of atrial fibrillation. The DR-FLASH score (score based on diabetes mellitus, renal dysfunction, persistent form of atrial fibrillation, left atrialdiameter >45 mm, age >65 years, female sex, and hypertension) is reportedly useful for identifying patients with arrhythmogenic substrates. We hypothesized that, in patients with persistent atrial fibrillation, the DR-FLASH score can be used to classify patients into those who require PVI-plus and those for whom a PVI-only strategy is sufficient. Methods and Results This study is a post hoc subanalysis of the
