Implantable Cardioverter Defibrillator (ICD) Implantation

What is an ICD and why is an ICD implantation done?

An implantable cardioverter defibrillator (ICD) is a device that is implanted in the chest to monitor for and, if necessary, correct abnormal heart rhythms.




How is the procedure done?

  • This insertion site, either the chest wall or the abdomen, is numbed and a small pocket is made
  • Another incision is made in the vein just under the collarbone through which the wires of the ICD are passed and attached to the inner surface of the heart.
  • The other ends of the wires are connected to the main box of the ICD (containing the generator), which is inserted into the pocket created.
  • The ICD is tested for good response several times by causing the heart to fibrillate after which the incision is closed
