In 6 patients with malignant ventricular arrhythmias we have tried to implant a non-thoracotomy system in combination with Medtronic Pacer-Cardioverter-Defibrillator. In 5 pts the implantation criteria were met (84%). In testing multiple lead configurations (including coronary sinus location) and polarities the DFT was 15 J in 3 cases and 10 J in 2 cases. No complications were observed during the peri- and post-operative period. Predischarge testing confirmed the efficacy of such devices in terminating induced ventricular tachyarrhythmias. During follow-up (mean 3 ± 2.5 months) one spontaneous high rate sustained VT was correctly terminated. The high success rate in reaching low DFT and the absence of complications encourage the implanting of a non-thoracotomy lead system as a standard approach in device therapy for ventricular tachyarrhythmias.
