The learning curve associated with the introduction of the subcutaneous implantable defibrillator

The subcutaneous implantable cardioverter defibrillator (S-ICD) was introduced to overcome complications related to transvenous leads. Adoption of the S-ICD requires implanters to learn a new implantation technique. The aim of this study was to assess the learning curve for S-ICD implanters with respect to implant-related complications, procedure time, and inappropriate shocks (IASs).In a pooled cohort from two clinical S-ICD databases, the IDE...
