Successful cryoballoon ablation of a focal atrial tachycardia in a patient with situs inversus and dextrocardia

Abstract

Cryoballoon ablation of an arrhythmogenic focus alongside a pulmonary vein as an alternative to radiofrequency ablation may be feasible and safe in patients with situs inversus and dextrocardia.

Combining with Intracardiac Echocardiography and Radiofrequency Catheter Ablation of Focal Right Atrial Tachycardia in Dextrocardia: Challenge and Literature Review

“…In recent years, in addition to radiofrequency ablation, balloon cryoablation has also been used to treat arrhythmias in patients with dextrocardia. Akkaya et al 16 reported the first case of cryoballoon ablation in a patient with focal atrial tachycardia in dextrocardia. The successful ablation of abnormal potentials originating in the superior pulmonary vein inferior to the ramus under the guidance of the Ensite system suggests that cryoballoon ablation may also be safe and feasible in patients with dextrocardia combined with arrhythmias.…”
