Successful ablation of atrioventricular nodal reentrant tachycardia in a patient with coexistent congenitally corrected transposition of the great vessels and situs inversus.

Congenitally corrected transposition of the great vessels (CTGV) is a rare congenital cardiac and great vessel abnormality. The anomalous inversion of the ventricles and great vessels makes performing catheter ablation difficult. We herein report a successful case of atrioventricular node reentrant tachycardia ablation in a patient with coexistent CTGV and situs inversus.
