Remote magnetic navigation ablation of incisional atrial flutters in adolescent with a giant right atrium after surgical correction of tetralogy of Fallot and Ebstein's anomaly

Abstract

We describe a clinical case of a 17-years-old adolescent with congenital heart disease after three open-heart surgery procedures for correction of tetralogy of Fallot and Ebstein's anomaly who presented with drug-resistant, persistent atrial flutter and giant right atrium (8.2 cm by transthoracic echocardiography). The successful ablation procedure of the two types of incisional atrial flutter was performed using remote magnetic navigation without any complications with 2.2 minutes of fluoroscopy. The patient remained free of any arrhythmias without antiarrhythmic drugs during 12 months of follow-up with a reduction of right atrium size (5.8 cm by transthoracic echocardiography).
