Key result
Redesigned nonthoracotomy defibrillator leads achieve ~64% successful implantation, limited by high defibrillation thresholds.

Does a nonthoracotomy defibrillator lead system allow successful implantation in patients requiring an ICD?
Initial clinical experience with a nonthoracotomy ICD lead system demonstrated successful implantation in 9 of 14 patients, though high defibrillation thresholds precluded use in the remainder.
Moore et al. (1991) conducted a cohort in Recurrent sustained ventricular tachycardia or aborted sudden cardiac death (n=14). Nonthoracotomy defibrillator lead system was evaluated on Primary successful lead system implantation. A redesigned nonthoracotomy defibrillator lead system achieved primary successful implantation in 64.3% (9 of 14) of patients, with the remainder having unacceptably high defibrillation thresholds.
