title: Intra-atrial Reentrant Tachycardia in Complete Transposition of the Great Arteries Without Femoral Venous Access.
abstract: Catheter ablation for patients with transposition of the great arteries (d-TGA) requires multiple considerations and careful preprocedural planning. Knowledge of the patient's anatomy and surgical correction, in addition to electroanatomic mapping and entrainment maneuvers, are important to identify and successfully treat arrhythmias. This case was unique in that the lack of femoral venous access required transhepatic venous access and bidirectional block was attained with ablation lesions along the cavotricuspid isthmus on both sides of the baffle.
