We report the case of a 58 years old male affected by a severe relapsing ventricular tachycardia despite a well administered anti arrhythmic therapy. Etiology is an arrhythmogene right ventricular dysplasia. Considering the severity of this arrhythmia we proceed to percutaneous implantation of an automatically implantable defibrillator under local anesthesia. Evolution was favorable with a follow-up of 3 months.
