  4. Heart Valve Replacement Surgery - Topic Overview

    Valve replacement surgery is generally performed as an open-heart procedure in the operating room of a hospital. It may also be done as a minimally invasive surgery.Although valve surgery is an intricate procedure, it is also common. In the majority of cases, valve replacement surgery is a straightforward procedure with a high rate of success and a low risk of complications. A cardiac surgeon, who specializes in heart surgery and has had years of training, will do the surgery. A team of nurses, an anesthesiologist, and possibly a surgical resident will assist the surgeon.In rare cases, a more complex operation is done. The aortic valve may be replaced with one of the person's other heart valves (usually the pulmonary valve between the lower right heart chamber and the opening to the artery that goes to the lungs). Since the pulmonary valve is used in the heart to replace the aortic valve, an artificial valve is implanted to replace the pulmonary valve. This type of valve surgery may

  9. Hypertrophic Cardiomyopathy - Topic Overview

    What is hypertrophic cardiomyopathy?Hypertrophic cardiomyopathy (say hy-per-TROH-fik kar-dee-oh-my-AWP-uh-thee) happens when the heart muscle grows too thick, so the heart gets bigger and its chambers get smaller. Many people have no symptoms and live a normal life with few problems. But in some people with this condition:The heart doesn't get enough blood and oxygen, which can cause chest pain. A fast, slow, or uneven heartbeat (arrhythmia) develops. In rare cases, this can cause sudden death. The heart doesn't pump blood well, or it doesn't relax between beats as it should. In rare cases, this can lead to heart failure.People who exercise often and hard may have changes in their heart muscle that can be confused with hypertrophic cardiomyopathy. This condition is called athlete's heart syndrome. It is harmless. When an athlete stops training, the heart will return to a normal size. What causes hypertrophic cardiomyopathy?Certain genes cause the heart to grow more than it should.
