Key result
Delayed defibrillation testing 2 months after CRT-D implantation was effective at first shock in 96% of patients, with a 1% acute LV lead dislodgment rate and no ICD therapy failures.

Should not yet change practice for defibrillation testing timing after CRT-D; leaves open need for randomized confirmation of safety.

Is delayed defibrillation testing at 2 months safe and feasible in heart failure patients implanted with CRT-D?
Delayed defibrillation testing 2 months after CRT-D implantation is safe and feasible, demonstrating a high rate of effective first shocks and low complication rates.
Gasparini et al. (2005) conducted a cohort in Heart failure patients treated with CRT-D (n=211). Delayed defibrillation testing (2 months post-implantation) vs. Immediate defibrillation testing (at end of implantation) was evaluated on First shock effectiveness at delayed defibrillation testing. Delayed defibrillation testing 2 months after CRT-D implantation was effective at first shock in 96% of patients, with a 1% acute LV lead dislodgment rate and no ICD therapy failures.
