The purpose of this study is to compare the incidence of cardiac implantable electronic device (CIED) infection and CIED mechanical complication after CIED replacement with a high-power cardiac implantable electronic device; either a cardiac resynchronization therapy device (CRT), or an implantable cardioverter defibrilator (ICD) and TYRX Anti-Bacterial Envelope (formerly known as "AIGISRx"), to the incidence, after replacement with an ICD or CRT and no TYRX.
