Journal of the American College of Cardiology. This is a very fast heartbeat caused when the muscles in the atria contract quickly. 2020 ACC/AHA guideline for the management of patients with valvular heart disease: A report of the American College of Cardiology/American Heart Association Joint Committee on Clinical Practice Guidelines. Approach to the infant or child with a cardiac murmur. Auscultation of cardiac murmurs in adults. Evaluating chest pain and heart murmurs in pediatric and adolescent patients. A heart valve problem can cause a murmur. When rheumatic fever affects the heart valves, it's called rheumatic heart disease. Rheumatic fever may occur in those who don't get or complete treatment for strep throat. This is a serious complication of strep throat. A murmur may occur if the infection is untreated and affects the heart valves. Atrial flutter, another common pathological supraventricular tachycardia, occurs much less frequently than atrial fibrillation. The germs spread through the blood to the heart from another part of the body, such as the mouth. Bacteria or other germs cause this infection. Infection of the inner heart lining and valves (endocarditis). Nearly half of all patients with heart failure have a normal ejection fraction (EF).When calcium affects the heart valves, it's called calcific or degenerative valve disease. The changes in blood flow create a murmur. A calcified valve also may not close completely, letting blood flow backward. Calcium deposits can cause a heart valve - such as the mitral valve or the aortic valve - to become stiff and narrow (valve stenosis). Things that can damage the heart valves include: In adults, worrisome heart murmurs are usually due to heart valve problems that develop later in life (acquired heart valve disease). A heart structure problem present before birth (congenital heart defect) causes irregular blood flow between the heart chambers or blood vessels. Examples are atrial septal defect and ventricular septal defect. A hole may form before birth in the wall between the upper or lower heart chambers, or both. In children, worrisome murmurs are usually due to a problem with the heart's structure that's present at birth (congenital heart defect).Ĭongenital causes of worrisome heart murmurs include:
