[Simplified approach to ablation in atrial flutter using a single catheter electrode. Based on 70 cases].

The object of this study was to assess the feasibility, efficacy and risks of ablation of common atrial flutter using a single catheter electrode. Recent studies have shown that radiofrequency ablation is effective for interrupting atrial flutter but with a variable rate of recurrence. Therefore, the search for a conduction block in the isthmic region has become the reference method for reducing the incidence of recurrence but this requires the use of costly material.
