Heart Surgery and its Risks

What Is Heart Surgery and its Risks?

Heart surgery is done to correct problems with the heart. Your provider may recommend surgery after lifestyle changes, medicines, or other procedures no longer work. Heart surgery may also be done in an emergency situation, such as a heart attack. Each year, more than 2 million people around the world have open-heart surgery to treat various heart problems.
