Introduction: Catheter ablation of an accessory pathway can be challenging in patients with recurrent episodes of atrial fibrillation. The use of antiarrhythmics can significantly interfere with the accessory pathway, making its catheter mapping impossible.

Methods: This case report describes the use of ibutilide to prevent atrial fibrillation during endocardial catheter mapping and ablation of a right lateral accessory pathway in a young patient without significantly interfering on accessory pathway.

Conclusion: Successful catheter mapping and ablation of a right accessory pathway in a young patient with episodes of atrial fibrillation using ibutilide.
