Who Should Receive the Subcutaneous Implanted Defibrillator?

in the ICD population, the long-term risks of lead malfunction and infection become greater concerns.Studies have shown that >20% of patients will have a lead failure by 10 years, and this observation does not include recalled leads, such as Fidelis and Riata, that have shown much higher failure rates.[9][10][11] given the short-and long-term risks of ICDs, it is important to select the right device carefully for each patient.Indiscriminate use of CRT, dual-chamber ICDs, suboptimal programming, or poorly designed transvenous leads undermines the role of these devices to prevent SCD.It is in this context that the subcutaneous (S)-ICD should be considered for patients without pacing needs undergoing ICD implantation.
