In adults, abnormal murmurs are most often due to acquired heart valve problems.Likewise, do heart murmurs in babies go away?
About one out of 100 babies is born with a structural heart problem (also known as congenital heart defect), so most heart murmurs are not caused by heart problems.

How are heart murmurs diagnosed in a child? - Chest X-ray. An X-ray creates images of the heart and lungs.
- Electrocardiogram (ECG). This test that measures the electrical activity of the heart.
- Echocardiography (echo). An exam that uses sound waves (ultrasound) to look at the structure and function of the heart.
How do they fix a heart murmur?
Options include: - Open-heart surgery. This is the primary surgical treatment for severe valve stenosis.
- Transcatheter aortic valve replacement (TAVR). A less invasive approach, TAVR involves replacing the aortic valve with a prosthetic valve via an artery in your leg or in a small incision in your chest.
Can a child grow out of a heart murmur?

Heart murmurs are common, especially among young children. They are usually normal and are called innocent heart murmurs.Are heart murmurs hereditary?
The risk for valve calcification increases with age. People who have rheumatic fever as children are more likely to have heart valve abnormalities in adulthood. Some causes for heart murmurs (e.g., cardiac myxoma, hypertrophic cardiomyopathy, congenital heart disease) have genetic (hereditary) risk factors.Does heart murmur cause arrhythmia?
An arrhythmia is a heartbeat that is irregular, too fast, or too slow. AFib is the most common type of arrhythmia. Heart murmurs are not necessarily a sign of AFib. Murmurs are related to how blood is flowing through your heart, particularly the valves that connect the chambers of your heart.What percent of heart murmurs are innocent?
