ICDs are implanted under local anaesthesia in a sterile operating room or catheterization laboratory. Transvenous ICD implantation starts, like pacemaker implantation, with inserting the ICD leads in the left or right cephalic vein. Fluoroscopy is used to ensure the appropriate location in the atrium or ventricle. Leads are often positioned in the auricle of the right atrium and/or the right ventricular apex. | ICDs are implanted under local anaesthesia in a sterile operating room or catheterization laboratory.
