ANATOMY

Detailed explanation-1: -Calcium deposits can cause a heart valve-such as the mitral valve or the aortic valve-to become stiff and narrow (valve stenosis). A calcified valve also may not close completely, letting blood flow backward. The changes in blood flow create a murmur.

Detailed explanation-2: -A murmur means blood is flowing abnormally across your heart valves. A murmur may mean there’s a problem with your heart. But heart murmurs are also present in healthy people who don’t have a heart problem (called “innocent” heart murmurs).

Detailed explanation-3: -A heart murmur is a blowing, whooshing, or rasping sound heard during a heartbeat. The sound is caused by turbulent (rough) blood flow through the heart valves or near the heart.

Detailed explanation-4: -Complications of an abnormal heart murmur will vary depending on the cause. Possible complications include: Heart failure, when the heart is so weak it no longer pumps blood well. Infection of the heart’s valves or inner lining (infective endocarditis)
