Atrial flutter – a curable arrhythmia?

Objective: NU CORESPUNDE!!!!!!!! Atrial flutter re-presents a heterogeneous group of atrial tachycardias produced through macroreentry. Radiofrequency abla-tion has great success rate in restoring back the sinus rhythm as well as preventing the relapses.

Methods: A longitudinal retrospective study was per-formed on a group of 197 atrial flutter patients divi-ded into 2 groups: 86.3% (n=170) patients with typical atrial flutter, 23.35% (n=46) patients with atypical atrial flutter. The patients were monitored for an average of 41 months at a rate of 1, 3 and 6 months by lead electro-cardiographic Holter recordings, followed by annually telephone interviews. The statistical analysis of the data was made using SPSS Statistics® Ver 25, Microsoft® Of-fice Excel for Windows 2016.

Results: In the typical atrial flutter group, the success rate of ablation procedure was 100% (n=170). Only 5 cases (2.94%) of typical atrial flutter recurrences were recorded during the follow-up. Patients with flutter relapse underwent a second radiofrequency ablation procedure with a success rate of 100%. No relapses had ever occurred during the entire duration of the follow-up. In the atypical atrial flutter group, the success rate of the aforementioned procedure was 95.65% (n=44). During the follow-up, a number of 7 (16.27%) patients experienced a new episode of atypical flutter, being re-corded as arrhythmic recurrence. For 5 of them, a se-cond procedure was performed with 100% success rate, achieving the sinus rhythm without any recurrence of arrhythmia during the follow-up.

Conclusions: Transcatheter radiofrequency ablation of typical and atypical flutter has a great success rate, de-monstrating curability to an overwhelming percentage of patients.
