摘要

Typical atrial flutter, counterclockwise or clockwise movement around the tricuspid annulus, has been well studied. However, the reentrant circuits in atypical atrial flutter are not well defined. A patient without a prior history of cardiac surgery who presented with incessant atypical atrial flutter is described. Activation mapping demonstrated a circular movement around the fossa ovalis in the interatrial septum. Entrainment mapping demonstrated a protected isthmus between the right pulmonary veins and the fossa ovalis. Radiofrequency ablation of this isthmus terminated atrial flutter without recurrence during the follow-up period.
