[Radiofrequency catheter ablation of atrial flutter]

Area of Science:

• Cardiology
• Electrophysiology
• Medical Devices

Background:

• Atrial flutter anatomy is well-understood, with radiofrequency catheter ablation (RFA) established as a primary treatment.
• Various recording and ablation techniques are available for managing atrial flutter.

Purpose of the Study:

• To evaluate the efficacy and safety of radiofrequency catheter ablation (RFA) for treating atrial flutter.
• To assess the role of RFA as a first-line treatment for recurrent or incessant atrial flutter.

Main Methods:

• Conducted 108 RFA procedures for atrial flutter in 84 patients between 1999-2000.
• Atrial flutter cases constituted approximately 20% of all RFA procedures for re-entry tachycardias during the study period.
• Treated 85 patients (71 male, 14 female, mean age 57 ± 12 years) with a mean atrial flutter history of nine years.

Main Results:

• Achieved a 96.5% success rate for radiofrequency catheter ablation (RFA) during the first treatment session.
• No serious complications were reported during or after the RFA procedures for atrial flutter.
• Patients experienced successful treatment after previous interventions including drug trials and pacing.

Conclusions:

• Radiofrequency catheter ablation (RFA) is a safe and highly effective treatment for atrial flutter.
• RFA should be considered the primary treatment of choice for patients experiencing recurrent or incessant atrial flutter.
• The study supports the established role of RFA in managing complex cardiac arrhythmias like atrial flutter.
