| Popis: | MARROUCHE, N.F., et al.: Use of Different Catheter Ablation Technologies for Treatment of Typical Atrial Flutter: Acute Results and Long-Term Follow-Up.Objectives: We report the acute success and long-term follow-up in consecutive patients undergoing catheter ablation of typical right atrial flutter (AFL) using different ablation technologies. Methods: One hundred and two patients presenting for treatment of AFL to our laboratory were included in the study. Based on availability and physician preference, ablation was performed with either a cooled-tip catheter (39 patients, group I), an 8- or 10-mm tip catheter connected to a high-power radiofrequency (RF) generator (25 patients, group II), or a 4- or 5-mm tip catheter (38 patients, group III). Acute ablation success was achieved in all group II and group III patients. Among the 38 patients undergoing ablation with the conventional catheter tip (group I), crossover to an 8-mm tip or a cooled tip ablation catheter was required in 11 patients (29%). The mean fluoroscopy time was significantly higher in group I(54.3 ± 26.4 minutes)when compared to group II(39.6 ± 19.6 minutes; P < 0.05)and group III(40 ± 16 minutes; P = 0.0.5). After a mean follow up of20 ± 5months no patient in group II experienced recurrence of AFL, whereas 18.4% (7 of 38 patients;P < 0.05) in group I and 10% (4 of 39 patients;P < 0.05) in group III had recurrence of AFL. Ablation technologies designed to obtain larger size lesions appeared to be more effective in achieving acute ablation success of AFL and in limiting the long-term recurrence rate of this arrhythmia.
