Clinical Series

The study population consisted of 17 men and five women. The mean age at the time of the first ablation was 38±14 years (mean±SD), range 20 to 70 (Fig. 19.1). The mean left ventricular ejection fraction (LVEF) was 59±10%. It was below 45% in two patients (Fig. 19.2).

Two patients who had an implantable defibrilla-tor had ablation for the treatment of frequent and poorly tolerated episodes of VT. Four patients had incessant VT at the time of the first ablation. One patient had previous antiarrhythmic surgery performed at La Salpêtrière hospital, 23 years before the first ablation procedure.

Fig.19.1 • Distribution of age at first ablation in the present series of 22 patients. Note the wide spectrum at which the severe form of arrhythmia (resistant VT) occurred. It is possible that this distribution may be skewed toward the younger age since some of the older patients may have died of congestive heart failure before developing severe arrhythmias
