Atrial Fibrillation after Atrial Flutter Ablation: An Existential Journey to Escape an Inevitable Fate

Atrial flutter is a sustained cardiac dysrhythmia that usually involves a single macroreentrant atrial circuit rotating around a large central functional or anatomic obstacle , and similar to atrial fibrillation (AF), accounts for a significant proportion of arrhythmia-related emergency department consultations and hospital admissions.1 Atrial flutter is most commonly classified as "typical", when dependent on a critical isthmus between the tricuspid annulus and the inferior vena cava (cavotricuspid isthmus), or "atypical" when the critical isthmus resides elsewhere (e.g.
