Implication

Supports activation potential-guided ablation for Mahaim fibers in small series; leaves open validation in prospective trials.

Structured PICO

Does catheter ablation guided by the activation potential effectively treat paroxysmal tachycardias in patients with atriofascicular Mahaim fibers?

Population

6 patients (5 females, mean age 26 +/- 7.3 years) with paroxysmal tachycardias with a wide QRS complex and diagnosed atriofascicular Mahaim fibers.

Intervention

Catheter ablation in sinus rhythm guided only by the recording of the activation potential of the fiber.

Outcome

Efficacy in ablation

Catheter ablation of Mahaim fibers guided solely by the activation potential in sinus rhythm is highly effective and safe.
