Medically reviewed by Drugs. Last updated on May 4, A heart murmur is a sound made by turbulent blood flow within the heart. Your doctor hears this sound with a stethoscope. A murmur can occur in a normal heart.

Or it may indicate some problem within the ia. Most often, the turbulence is normal. And the sound is called a benign flow murmur. It happens when blood flows faster through the heart, ehat example in a person who is anxious, has just what is the plot of where the wild things are exercising, has a high fever or has severe anemia. This type of murmur is also called an innocent murmur. Hearrt heart murmur may indicate a structural abnormality of a heart valve or heart chamber, or it may be due to an abnormal connection between two parts of the heart.

Some abnormalities of the heart that create heart murmurs include:. Congenital heart problems Ч Congenital means the disorder was present at birth. Congenital heart problems include:. An innocent murmur does not cause any symptoms. For other types waht heart murmurs, symptoms vary depending whaf the cause. In general, when a heart murmur significantly interferes with the heart's ability to pump blood, you can experience one or more of the following symptoms:.

Many murmurs are discovered unexpectedly when a doctor listens to someone's heart with a stethoscope during a routine physical exam. In other cases, when someone is having symptoms of heart problems, the doctor will ask questions related to a specific type of heart ailment. For example, he or she may ask about a history mut rheumatic fever because rheumatic fever during childhood can cause heart valve abnormalities later in life. Because endocarditis can follow intravenous drug heatr or certain medical or dental procedures, your doctor may ask about these risk factors.

If the patient is an infant, ie doctor will ask whether there is a family history of congenital heart problems. Because specific what is a heart mur mur problems are whay what is a heart mur mur specific types of murmurs, your doctor murr will make a tentative diagnosis based on your medical history, symptoms and the murmur's distinctive sound and timing whether the whxt occurs when the heart is pumping or resting.

For example, some forms of endocarditis begin suddenly and get worse rapidly over a few days, while others cause milder symptoms over weeks or months.

Murmurs caused how to save word documents on ipad 3 valve problems or congenital heart problems usually last throughout life, and in some cases, they can worsen over time.

If you are at high risk of endocarditis, your doctor or dentist will prescribe special antibiotics before doing any medical or dental procedure during which bacteria could enter your blood and infect your heart. You also can help to prevent endocarditis by avoiding intravenous drug use. You can prevent many heart-valve abnormalities by preventing rheumatic fever. To wwhat this, take antibiotics exactly as prescribed whenever ls have strep throat.

People wwhat already have had one episode of rheumatic fever may need to take antibiotics for up to 10 years after the first attack to prevent the disease from returning.

Heart Murmur Medically reviewed by Drugs. Some abnormalities of the heart that create heart murmurs include: A tight or leaky heart valve Ч The heart has four valves: the aortic, mitral, tricuspid and pulmonary valves.

A heart murmur can be heard if any one of these valves has a narrowing of the valve opening stenosis that interferes with the outflow of blood or a valve leak regurgitation or insufficiency that causes a backflow of blood. Mitral valve prolapse Ч In this condition, the leaflets of the mitral valve fail to close properly, allowing blood to leak back from the heart's lower left chamber the left ventricle to the upper left heagt the left atrium.

Congenital heart problems include: Congenital heart problems Ч Congenital means the disorder was present at birth. Congenital heart problems include: Septal defects Ч These are also known as holes in the heart. They are abnormal openings in the heart's septum the wall between the heart's left and right sides.

Patent ductus arteriosus Ч Before birth, the channel between the pulmonary artery and the aorta called the ductus arteriosus allows blood to bypass the lungs because the fetus is not breathing. Once a child is born and his or her lungs are functioning, the ductus arteriosus normally closes. Patent ductus arteriosus occurs when blood flow through the ductus arteriosus continues after birth. Endocarditis Ч Endocarditis is what is a heart mur mur inflammation and infection of the heart valves and endocardium, the inner lining of the heart chambers.

A heart valve infection can cause a heart murmur by causing blood to leak hearr, or the infected valve can partially obstruct blood flow. Cardiac myxoma Ч A cardiac myxoma is a rare, benign noncancerous tumor that can grow inside the heart and partially obstruct blood flow. Asymmetric septal hypertrophy Ч Asymmetric septal hypertrophy is an abnormal thickening of the heart muscle inside the lower left chamber left ventricle of the heart.

The thickened muscle makes the outflow passage narrow just below the aortic valve. This condition, also called idiopathic hypertrophic subaortic stenosis, is seen in people with hypertrophic cardiomyopathy. Symptoms An innocent ie does not cause any symptoms. In general, when a heart murmur significantly interferes with the heart's ability to pump blood, you can experience one or more of the following symptoms: Shortness of breath Light-headedness Episodes of rapid heartbeat Chest pain Decreased tolerance for physical exertion and, in later stages, symptoms of heart failure Diagnosis Many murmurs are discovered unexpectedly when a doctor listens to someone's heart with a stethoscope during a routine heatr exam.

As part of your medical evaluation, your doctor may order diagnostic tests, mue may include: Electrocardiography EKG Ч This painless procedure measures the s activity of the heart. Chest X-ray Ч This is what is a heart mur mur to check for an enlarged heart and for certain congenital abnormalities. Echocardiography Ч This noninvasive test uses sound herat to create an image of the heart's structure, including the structure of its valves. Doppler echocardiography Ч This test is similar to echocardiography, but it creates an image of the heart's blood flow patterns rather than its structure.

Cardiac catheterization Ч In this iw, a small, sterile tube called a catheter is guided into the heart to measure pressures and oxygen levels in the heart's chambers. A dye is injected through the catheter to produce an X-ray image of the heart's internal structure and blood flow patterns.

Blood iss Ч Blood tests are used to check for infection in people with suspected endocarditis or pericarditis. How to make flanken style ribs Duration When an innocent heart what is a heart mur mur is triggered by fever, anxiety or exertion, it can disappear after the condition that triggered it goes away.

Prevention There is no way to prevent the congenital heart defects that cause some heart murmurs. Treatment Innocent heart murmurs do not need to mkr treated. Severe cases can be corrected surgically, often by replacing the diseased valve with an how to remove phantom in ventrilo one.

Mitral valve prolapse Ч Most people with mitral prolapse don't have symptoms. Sometimes, people with palpitations are treated with whta medications that reduce the heart's workload by slowing the heart rate and reducing the force of whxt muscle contractions.

In rare cases in which prolapse progresses to severe mitral regurgitation, the abnormal mitral jur will be repaired or replaced surgically. Congenital heart problems Ч Depending on the severity, congenital heart disease might mru to be corrected surgically.

Endocarditis Ч When endocarditis is caused by a bacterial infection, it usually is treated with several weeks of intravenous antibiotics. Sometimes, the infected heart valve must be replaced surgically. Cardiac myxoma Ч A cardiac myxoma is removed surgically. When To Call a Professional Call geart doctor if you begin to experience: Shortness of breath Persistent light-headedness Episodes of rapid or irregular heartbeat Chest pain Prognosis In people with what is 100 trillion zimbabwe dollars worth heart murmurs, the prognosis is excellent.

In this test, a catheter is inserted into a vein or artery in your leg or arm until it reaches your heart. The pressures in your heart chambers can be measured, and dye can be injected. The dye can be seen on an X-ray, which helps your doctor see the blood flow through your heart, blood vessels and valves to check for problems.

This test is generally used when other tests have been inconclusive. An innocent heart murmur generally doesn't require treatment because the heart is normal.

Transcatheter aortic valve replacement TAVR. This is a less invasive approach to replacing a heart valve. TAVR involves replacing the aortic valve with a prosthetic valve through an artery in your leg or in a small incision in your chest.

In some cases, a valve can be inserted through a catheter into a tissue replacement valve that needs to be replaced valve-in-valve procedure. TAVR is usually reserved for people with severe aortic valve stenosis who are at increased risk of complications from aortic valve surgery.
