Case Report (n=1)
This case highlights that focal atrial tachycardia can occur in patients with surgically repaired Tetralogy of Fallot and may arise from sites unrelated to the surgical scar, such as the crista terminalis.
Mapping non-scar sites such as the crista terminalis may be considered in focal AT post-TOF repair; leaves open whether this alters standard ablation approaches.
Tetralogy of Fallot (TOF) is a cyanotic congenital heart disease which, without corrective surgery, has a poor prognosis. These patients have an increased incidence of arrhythmias both supraventricular and ventricular post surgical correction. The supraventricular arrhythmias are usually related to the scar tissue at the surgical repair site. We present a case of a young male patient status post TOF repair who presented with a supraventricular tachycardia which was found to be unrelated to his surgical scar.

Mario Gonzalez (2014) conducted a case report in Focal Atrial Tachycardia in Surgically Corrected Tetralogy of Fallot (n=1). Electrophysiology study and radiofrequency ablation was evaluated on Termination of tachycardia.
