This article discusses 2 specialized implantable cardioverter defibrillator (ICD) devices. A special type of implantable device is available for cardiac resynchronization therapy, which can also have a defibrillator, in which case it is called a CRT-D device. In patients who meet guidelines for eligibility, a CRT-D will diminish the number of significant cardiac events including death. A subcutaneous ICD device does not need any leads placed in the vascular system and therefore does not have some of the complications that may be seen with transvenous ICDs. Also, there are patients who are not candidates for a typical ICD implantation. On the other hand, there are important disadvantages to the subcutaneous ICD.
