Heart Murmurs

Heart Murmur Causes

Most heart murmurs are innocent: They are caused by blood flowing through healthy valves in a healthy heart and do not require treatment. However, heart murmurs can be caused by blood flowing through a damaged or overworked heart valve. Valvular abnormalities may be present at birth, may occur as part of the normal aging process, or may result from other heart problems, such as rheumatic fever, heart attacks, or infective endocarditis. Heart murmurs are abnormal sounds during your heartbeat cycle such as whooshing or swishing made by turbulent blood in or near your heart. These sounds can be heard with a stethoscope. A normal heartbeat makes two sounds like "lubb-dupp" (sometimes described as "lub-DUP"), which are the sounds of your heart valves closing.

Heart murmurs can be present at birth (congenital) or develop later in life. A heart murmur isn't a disease but murmurs may indicate an underlying heart problem.Most heart murmurs are harmless (innocent) and don't need treatment. Some heart murmurs may require follow-up tests to be sure the murmur isn't caused by a serious underlying heart condition. Treatment, if needed
