Use of certain medications, alcohol or illegal drugs by the mother during pregnancy.German measles (rubella) in the mother during pregnancy.Uncontrolled diabetes in the mother during pregnancy.Family history of heart problems linked to murmurs.Things that increase the risk of heart murmurs in babies includes: 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. 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).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: Sometimes, heart murmurs continue for life without causing serious health problems. Innocent heart murmurs may go away over time. Phases of rapid growth, such as adolescence.Lack of healthy red blood cells that carry oxygen to body tissues (anemia).Things that might change blood flow and cause an innocent heart murmur include: Innocent heart murmurs are common in newborns and children. Throughout the heartbeat (continuous murmur)Ī person with an innocent murmur usually has a typical heart.When the heart is emptying (systolic murmur).When the heart is filling with blood (diastolic murmur).The ECG in Acute MI.A heart murmur is caused by rapid, choppy (turbulent) blood flow through the heart.
