Heart surgery can correct certain heart problems when other treatments haven't worked or can't be used.

In some cases, heart surgery may be a medical emergency. For example, surgery for a severe heart attack may need to be done right away. In other cases, you can plan heart surgery ahead of time. Some heart surgeries are major operations, such as heart bypass surgery for blocked arteries in the heart. Other surgeries are more minor heart procedures, such as putting in a pacemaker.

There are different types of heart surgery that can help treat many heart conditions:

• An implantable cardioverter defibrillator (ICD) to help prevent sudden cardiac arrest.
• A biventricular pacemaker to coordinate the heart's pumping action so it's more powerful.
• A ventricular assist device to help the heart pump blood.
• A total artificial heart to pump blood for the heart.

The approach a surgeon uses to do heart surgery depends on your heart problem, your general health, and other factors. Approaches to heart surgery include:

• Open-heart surgery (also called traditional heart surgery) is when the surgeon cuts the chest open to reach the heart. Because it's difficult to operate on a beating heart, medicines are used to stop the heart. A heart-lung bypass machine keeps oxygen-rich blood pumping through the body during the surgery.
• Off-pump heart surgery is open-heart surgery on a beating heart without using a heart-lung bypass machine. The surgeon holds the heart steady with a device. Surgeons may use off-pump heart surgery to do coronary artery bypass grafts (CABG), but only in certain cases.
• Minimally invasive heart surgery uses small cuts between the ribs. The cuts may be as small as 2 to 3 inches. The surgeon inserts tools into the chest through the cuts. This type of heart surgery may or may not use a heart-lung bypass machine.
• Robotic-assisted surgery is a type of minimally invasive surgery. The surgeon uses a computer to control tools on the arms of a robot. This allows the surgeon to be very accurate when doing difficult operations.

Like all surgery, heart surgery has risks even though the results are often excellent. The risks include:

• Bleeding
• Infection, fever, and swelling
• A problem from anesthesia (medicine that makes you sleep during surgery)
• Arrhythmia
• Damage to the heart, kidneys, liver, and lungs
• Stroke

The risks of heart surgery tend to be higher if:

• The surgery is an emergency.
• You have other medical conditions, including:
  • Diabetes
  • Kidney diseases
  • Lung diseases
  • Peripheral artery disease (PAD)

An injury is damage to your body. It is a general term that refers to harm caused by accidents, falls, hits, weapons, and more. In the U.S., millions of people injure themselves every year. These injuries range from minor to life-threatening. Injuries can happen at work or play, indoors or outdoors, driving a car, or walking across the street.

Wounds are injuries that break the skin or other body tissues. They include cuts, scrapes, scratches, and punctured skin. They often happen because of an accident, but surgery, sutures, and stitches also cause wounds. Minor wounds usually aren't serious, but it is important to clean them. Serious and infected wounds may require first aid followed by a visit to your doctor. You should also seek attention if the wound is deep, you cannot close it yourself, you cannot stop the bleeding or get the dirt out, or it does not heal.

Other common types of injuries include:

• Animal bites
• Bruises
• Burns
• Dislocations
• Electrical injuries
• Fractures (broken bones)
• Sprains and strains
