8. Conclusion

Atrial flutter is relatively common atrial arrhythmia with the nearly similar morbidity and mortality to atrial fibrillation. However, it's highly amenable to RF ablation. This procedure has emerged as therapy of choice in the light of highly successful rate and low complication risk. The knowledge of the anatomy and electrophysiology of the atrial flutter circuit is essential to choosing the optimal site for elimination of reentry. An electroanatomic 3D mapping system is highly recommended to perform the full activation and voltage mapping in order to localize the circuit and critical isthmus targeted for effective ablation.
