Catheter ablation of ventricular insertion of Mahaim fiber using noncontact mapping system in a patient with mirror-image dextrocardia.
We report a case of mirror-image dextrocardia with antidromic atrioventricular reciprocating tachycardia via the Mahaim fiber. Using the noncontact mapping system, arborized ventricular insertion of the Mahaim fiber was identified and successfully ablated.
