Illustration of the inside of the heart

Also called: Cardiac surgery

Each day, thousands of people in the U.S. have heart surgery. There are many different types of heart surgery. Surgeries may be used to

  • Repair or replace the valves that control blood flow through the heart's chambers
  • Bypass or widen blocked or narrowed arteries to the heart
  • Repair aneurysms, or bulges in the aorta, which can be deadly if they burst
  • Implant devices to regulate heart rhythms
  • Destroy small amounts of tissue that disturb electrical flow through the heart
  • Make channels in the heart muscle to allow blood from a heart chamber directly into the heart muscle
  • Boost the heart's pumping power with muscles taken from the back or abdomen
  • Replace the damaged heart with a heart from a donor
