Successful Radiofrequency Ablation of an Atrial Flutter in an Elderly Patient With Uncorrected Ebstein's Anomaly.

Ebstein's anomaly is a rare congenital heart disorder that causes displacement of the tricuspid valve towards the apex of the heart. Patients with this anomaly rarely survive beyond the age of 70 without surgical correction. When such patients survive till adulthood, they tend to present with atrial arrhythmias. Although radiofrequency ablation is harder to successfully complete due to disrupted anatomy of the heart, it can be the best choice for terminating arrhythmias in such patients. Here, we present a case of a 76-year-old patient with an uncorrected Ebstein's anomaly that presented with atrial flutter and was treated successfully with radiofrequency ablation.
