Left free wall‐sided Mahaim type fiber and A‐V nodal reentry tachycardia: Unusual but not impossible combination

Abstract

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.
