    Abstract:
    Endocavitary catheter ablation consists of delivering an impulse of 160 to 240 joules via a catheter used for electrophysiological investigation resulting in an electrical discharge which, in addition to its thermal effects may alter the arrhythmogenic substrate mechanically. This method was used in 2 patients with resistant and recurrent VT after myocardial infarction complicated by ventricular aneurysm. Two sessions of catheter ablation were necessary in both patients, but in the second one a single shock was successful in critically ill patients with VT. The first patient has been followed up for 20 months and the second for 13 months. Under prophylactic antiarrhythmic therapy, neither patient has had recurrence of the ventricular arrhythmias which had previously led to their hospitalisation. Catheter ablation is therefore presented as a technique which may be performed in the electro-physiological laboratory and repeated in cases of incomplete efficacy. This method may be used successfully in the treatment of chronic VT after myocardial infarction complicated by ventricular aneurysm.
