Typical atrial flutter and atrial fibrillation are frequently observed
to coexist(1) . In the current context
of interventional electrophysiology, curative or at least definitive ablation
is available for both arrhythmias. Despite their coexistence, it is not clear whether
typical flutter ablation is necessary in all patients undergoing catheter
ablation of atrial fibrillation. The following review explores the
pathophysiology of both arrhythmias, their interrelationships and the available
data pertaining to this theme.
