are most heart murmurs benign?

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. Often, heart murmurs are harmless (innocent) and don't need treatment.

A heart murmur is an abnormal heart sound that is heard when listening to the heart with a stethoscope. It is cause by abnormal turbulent blood flow. Abnormal turbulent blood flow can occur when blood passes across abnormal heart valves or across abnormal structures within the heart.

Most innocent murmurs disappear when a child reaches adulthood, but some adults still have them. When a child's heart rate changes, such as during exercise, excitement or fear, the innocent murmur may become louder or softer.

Upon auscultation of an individual with mitral valve prolapse, a mid-systolic click, followed by a late systolic murmur heard best at the apex, is common. The length of the murmur signifies the time period over which blood is leaking back into the left atrium, known as regurgitation.

Causes include mitral valve prolapse, tricuspid valve prolapse and papillary muscle dysfunction. Holosystolic (pansystolic) murmurs start at S1 and extend up to S2. They are usually due to regurgitation in cases such as mitral regurgitation, tricuspid regurgitation, or ventricular septal defect (VSD).

A heart murmur exists in 40 to 45 percent of children and 10 percent of adults at some time in their lives. Murmurs can come and go. Since heart murmurs often don't cause noticeable symptoms, you could have a murmur and not even know it.

Much of the time, MVP doesn't cause any problems. Rarely, blood can leak the wrong way through the floppy valve. This can lead to palpitations, shortness of breath, chest pain, and other symptoms.

Signs and symptoms of mitral valve regurgitation, which depend on its severity and how quickly the condition develops, can include: Abnormal heart sound (heart murmur) heard through a stethoscope.

Ventricular septal defects are among the most common congenital heart defects, occurring in 0.1 to 0.4 percent of all live births and making up about 20 to 30 percent of congenital heart lesions. Ventricular septal defects are probably one of the most common reasons for infants to see a cardiologist.

Diagnosis. Doctors may diagnose mitral valve prolapse at any age. Your doctor is most likely to diagnose mitral valve prolapse while listening to your heart with a stethoscope during a physical examination. If you have mitral valve prolapse, your doctor may hear a clicking sound, which is common with this condition.

Valvular heart diseases, such as mitral regurgitation, aortic stenosis (AS) and aortic insufficiency, do not result in conditions of low flow in the left atrium, and do not apparently increase the risk of thromboembolism brought by AF.

Signs and symptoms of mitral valve regurgitation, which depend on its severity and how quickly the condition develops, can include: Abnormal heart sound (heart murmur) heard through a stethoscope. Shortness of breath (dyspnea), especially when you have been very active or when you lie down.

(Because of these sounds, MVP is sometimes called click-murmur syndrome, floppy valve syndrome, or balloon mitral valve.) In most cases, the cause of MVP is unknown. Sometimes kids are born with the condition.

The cardiologist may have you do other tests such as an electrocardiogram (EKG) or echocardiogram to look for heart rhythm or structural problems and see how well your heart is working. A heart murmur itself does not require treatment.

Systolic murmurs are graded by intensity (loudness) from 1 to 6, with a stethoscope slightly removed from the chest. A grade 1 out of 6 is faint, heard only with a special effort. A grade 6 out of 6 (6/6) is extremely loud, and can be heard with a stethoscope even when slightly removed from the chest.

Listening to Your Heart Your doctor will use a stethoscope to hear your heartbeat. The opening and closing of your heart's valves make a "lub dub" noise.
