Case presentation In 2005, a 69-year-old woman was admitted to our Cardiology Department for an ablation procedure of a persistent atrial fibrillation. The patient was symptomatic for impaired functional status, and she was refractory to pharmacological treatment with antiarrhythmic drugs of class IA, IC, and amiodarone. Furthermore, she was affected by dextrocardia (atrial situs inversus, atrioventricular concor- dance and ventriculoarterial concordance) with situs viscerus inversus; the echocardiogram showed a mild biatrial enlargement with normal ventricular systolic function.
