A lead is a special wire that delivers energy from a pacemaker or implantable cardioverter defibrillator (ICD) to the heart muscle. Lead extraction is the removal of one or more leads from inside the heart.
Leads may need to be removed for any of the following reasons:
There are two approaches to lead extraction:
In either approach, a sheath is placed in the vein, threaded over the lead, and guided to the tip of the lead. The lead is then removed.
By participating in this quiz, or screening or health assessment, I recognize and accept all risks associated with it. I understand that the program will only screen for certain risk factors and does not constitute a complete physical exam. For the diagnosis of a medical problem, I must see a physician for a complete medical exam. I release Deborah Heart and Lung Center and any other organization(s) involved in this screening, and their employees and agents, from all liabilities, medical claims or expenses which may arise from my participation. Thank you for investing in your health by participating today.
