Ebstein’s anomaly (EA) is an uncommon congenital heart disease. Characterized by abnormal formed and apical displaced leaflets of the TV. The apical displacement of the tricuspid valve (TV) anatomically manifested by a morphological right atrium (RA), an atrialized segment of the right ventricle (RV), and the remaining functional RV. The TV is often regurgitant, resulting in right atrial and RV enlargement. The dilated right atrium in EA creates a fertile environment for atrial arrhythmias requiring radiofrequency ablation. Specific issues make the procedure more challenging in those patients. We report a case of successful radiofrequency ablation of cavo tricuspid isthmus-dependent atrial flutter in a patient of 59-year-old, with uncorrected Ebstein’s anomaly.
