Atrial arrhythmias are delayed manifestations after atrial switch procedures for d-transposition of the great arteries. Often times, these arrhythmias are intraatrial reentry tachycardias that arise in the pulmonary venous neo-atrium. Access and ablation in the pulmonary venous neo-atrium may require baffle puncture, risking damage to the baffle. We describe a case of neoatrial arrhythmia ablation in d-transposition of the great arteries using remote magnetic guided catheter navigation system using a retrograde approach without doing a baffle puncture.
