However, left atrial flutter that does occur late after ablation is amenable to interventional treatment with good prospects of success. Prevention of left atrial flutter can be achieved by induction of ablation lines as continuous and transmural as possible. Left atrial flutter is a relevant complication after RF catheter ablation of AF and was always associated with AF recurrence in our study population. Additionally, atrial flutter was documented during follow-up in 7 patients (4.7%) however, invasive electrophysiologic evaluation was not performed due to various reasons. Typical right atrial flutter occurred in 10 patients (6.7%) and was treated successfully by percutaneous RF ablation without recurrence in all patients. Nine of 10 patients (90%) were free from atrial flutter and 6 of 10 patients were free from AF after the second intervention. Left atrial flutter was associated with recurrence of AF in all 10 patients. Left atrial flutter observed in 10 patients (6.7%) was treated by recompletion of the ablation lines in all 10 patients. In 28 of 150 patients (18.7%), stable regular arrhythmias other than AF were detected during follow-up. The incidence of arrhythmia recurrences after AF ablation was analyzed during long-term follow-up using repetitive 7-day ECG recording. Both methods stop abnormal cells from sending signals. By using a thin electrode catheter to burn heart tissue, we try to stop the. Usually, providers use radiofrequency ablation (heat), but some use cryoablation to freeze the tissue that makes your heart beat too fast. We us atrial fibrillation ablation to treat arrhythmia (irregular heartbeats). One hundred fifty consecutive patients with paroxysmal or persistent AF were included in this prospective study. Atrial flutter ablation is a procedure to destroy cells in your heart that are causing atrial flutter, an abnormal rhythm of the heart. Recurrent atrial flutter or tachycar-dia post-ablation may be better managed with a repeat procedure as such arrhythmias can be difficult to rate control, frequently recur after cardioversion, and are often due to gaps in areas of prior ablation and have a relatively high success rate with repeat ablation. Atrial fibrillation after typical atrial flutter ablation: a long-term follow-up. However, late recurrent arrhythmias may complicate the patient's course. Assessing arrhythmia burden after catheter ablation of atrial fibrillation using an implantable loop recorder: the ABACUS study. RF ablation is an effective treatment for patients with AF. The aim of the study was to determine the incidence of atrial flutter and other arrhythmia recurrences (other than atrial fibrillation ) during long-term follow-up after left atrial substrate modification by percutaneous radiofrequency (RF) ablation of AF.
