Key result
Right-sided ICD implantation is linked to a ~225% higher intraoperative testing failure rate versus left-sided.
Why the study?
Does right-sided ICD implantation increase the failure rate of initial intraoperative testing compared to left-sided implantation in patients receiving a first ICD?
Population
870 patients treated with a first implantable cardioverter-defibrillator from July 2005 until May 2012…
Comparison
Right-sided ICD implantation (n=39, 4.5%) vs Left-sided ICD implantation (n=831, 95.5%)

May warrant intraoperative testing for right-sided ICDs; leaves open whether practice should change pending randomized data.

Does right-sided ICD implantation increase the failure rate of initial intraoperative testing compared to left-sided implantation in patients receiving a first ICD?
Absolute Event Rate: 13% vs 4%
p-value: p=0.023
Right-sided ICD implantation is associated with a significantly higher rate of initial intraoperative defibrillation testing failure compared to left-sided implantation, suggesting that intraoperative testing remains necessary for right-sided devices.
Keyser et al. (2013) conducted an observational in Patients requiring first implantable cardioverter-defibrillator (ICD) (n=870). Right-sided ICD implantation vs. Left-sided ICD implantation was evaluated on Failure of initial intraoperative testing of the implanted system (DFT > 21 J) (p=0.023). Right-sided implantation of implantable cardioverter-defibrillators resulted in a significantly higher rate of initial intraoperative testing failure compared to left-sided implantation (13% vs 4%, p=0.023).
