Dramatic reduction of ventricular tachycardia burden after dronedarone plus mexiletine treatment in a patient refractory to hybrid ablation.

Abstract

Antiarrhythmic drugs are often the last resort for recurrent ventricular tachycardia refractory to catheter ablation in implantable cardioverter-defibrillator carriers. Amiodarone, alone or combined with mexiletine, is usually but not always highly effective, and its use is usually limited by systemic adverse effects. We present the case of a 62 years old man with recurrent ICD shocks due to a VT refractory to an endo-epicardial hybrid ablation. Starting of dronedarone plus mexiletine combination showed an excellent result.
