Abstract

A 52-year-old patient with previous catheter ablation of A-V nodal reentrant tachycardia (AVNRT) had a redo procedure for reported recurrence. During the study, AVNRT was not inducible, but a previously unrecognized left-sided Mahaim-type accessory pathway was diagnosed and ablated successfully.

Keywords: A‐V nodal reentrant tachycardia; Mahaim fiber; accessory pathway; dual atrio‐ventricular node physiology; left free wall; radiofrequency catheter ablation.
