Radiofrequency catheter ablation of atypical atrial flutter masquerading as atrial fibrillation.
A patient with a surgically repaired double outlet right ventricle developed AF 6 months after successful RF catheter ablation of typical atrial flutter. Guided by a 64-electrode basket catheter, the patient's AF was found to be dependent on an atypical atrial flutter circuit rotating around the fossa ovalis. Successful RF catheter ablation was performed by creating a line of conduction block from the superior vena cava to the fossa ovalis.
