Heart Valve Diseases

What is Heart Valve Diseases?

What are heart valve diseases? Heart valve disease happens when one or more of your heart valves don't work well. Your heart has four valves: the tricuspid, pulmonary, mitral, and aortic valves. The valves have flaps that open and close. The flaps make sure that blood flows in the right direction through your heart and to the rest of your body. When your heart beats, the flaps open to let blood through. Between heartbeats they close to stop the blood from flowing backwards. If one or more of your heart valves doesn't open or close correctly, it can affect your blood flow and strain your heart. Fortunately, treatment helps most valve diseases. What are the types of heart valve diseases? Heart valves can have three basic kinds of problems: Regurgitation, or backflow, happens when the flaps of a valve don't close tightly. This allows the blood to leak backwards. A common cause of regurgitation is prolapse, where the flaps of the valve flop or bulge back. Prolapse most often affects the mitral valve. Stenosis happens when the flaps of a valve become thick, stiff, or stuck together. This prevents the heart valve from opening all the way. Not enough blood can pass through the valve. Aortic valve stenosis is a common type of stenosis. It affects the valve that controls blood flow into the large artery that carries blood out of the heart to the body. Atresia happens when a heart valve did not form properly and does not have an opening for blood to pass through. Sometimes a valve can have both regurgitation and stenosis. What causes heart valve diseases? Some people are born with heart valve disease. This is called congenital heart valve disease. It can happen alone or along with other congenital heart defects. Heart valve disease can also develop over time as you get older or have certain conditions that affect the heart. Who is more likely to develop heart valve diseases? Your chance of having heart valve disease is higher if: You are older. With age, the heart valves can become thick and stiff. You have or have had other conditions that affect your heart and blood vessels. These include: Rheumatic fever. An untreated strep throat can become rheumatic fever, which can harm the heart valves. The damage may not show up for years. Today, most people take antibiotics to cure strep throat before it can cause heart valve damage. Endocarditis. This is a rare infection in the lining of the heart and heart valves. It is usually caused by bacteria in the bloodstream. A heart attack. Heart failure. Coronary artery disease, especially when it affects the aorta (the large artery that carries blood from the heart to the body). High blood pressure. High blood cholesterol. Diabetes. Obesity and overweight. Lack of physical activity. A family history of early heart disease: A father or brother who had heart disease younger than 55. A mother or sister who had heart disease younger than 65. You were born with an aortic valve that wasn't formed right. Sometimes this will cause problems right away. Other times, the valve may work well enough for years before causing problems. What are the symptoms of heart valve diseases? Many people live their whole lives with a heart valve that doesn't work perfectly and never have any problems. But heart valve disease may get worse slowly over time. You may develop signs and symptoms, such as: Shortness of breath (feeling like you can't get enough air) Fatigue Swelling in your feet, ankles, abdomen (belly), or the veins in your neck Chest pain when you're physically active Arrhythmia, a problem with the rate or rhythm of your heartbeat Dizziness or fainting If you don't get treatment for heart valve disease, the symptoms and strain on your heart may keep getting worse. What other problems can heart valve diseases cause? When the valves don't work well, your heart has to pump harder to get enough blood out to the body. Without treatment, this extra workload on your heart can lead to: Heart failure Stroke Blood clots Su
