![]() However, previous studies showed that even in patients without previously documented atrial fibrillation (AF), the risk of new-onset AF after AFL ablation was relatively high ( 1– 4), rendering either a second AF ablation or a delayed AF management. Given the high success rate and low risk, radiofrequency catheter ablation (RFCA) is currently the first-line treatment of AFL. Typical atrial flutter (AFL) is a frequently encountered clinical tachyarrhythmia, especially occurring in elderly people.
