Heart murmurs usually don't mean there is anything wrong with your child's heart. Your doctor may call these murmurs "innocent" or "functional." An innocent murmur is just a noise caused by blood flowing through a normal heart. These noises are commonly heard in children because their hearts are very close to their chest walls. An innocent murmur can get louder or softer depending on your child's heart rate, such as when they're excited or scared. Doctors often hear heart murmurs when they check children who have a fever. Many innocent murmurs become hard to hear as children grow older and most usually go away on their own. Return to top What does it mean if my child has an innocent heart murmur?

Often, they are caused by turbulent blood flow through the heart valves. Considerations Return to top A doctor can evaluate heart sounds by listening with a stethoscope. They can be further evaluated with an echocardiogram to see what the exact cause of the murmur is. The heart has four chambers two upper chambers (called atria) and two lower chambers (ventricles). The heart has valves that temporarily close to permit blood flow in only one direction. The valves are located between the atria and ventricles, and between the ventricles and the major arteries from the heart. Normal heart sounds are called S1 and S2. They are the "lubb-dupp" sounds that are thought of as the heartbeat. These sounds are produced when the heart valves close.

What is a Heart Murmur? If you have a heart valve problem, your doctor has probably heard a sound called a murmur. To find out what kind of valve problem you have, your doctor may have ordered various tests, including an echocardiogram, an electrocardiogram, a chest x-ray, or cardiac catheterization. You may have taken medications to help treat your valve problem. If you have been referred to us, your doctor is recommending heart valve surgery. During this surgery, problem heart valves will either be repaired or replaced. What are Heart Valves? Your heart is a pumping muscle that works nonstop to keep your body supplied with oxygen rich blood. Four one-way heart valves keep blood moving in one direction through the heart. Problems with one or more valves may cause restriction of flow through the valve or leakage of the valve. How Normal Heart Valves Work The heart is divided into four chambers. The upper chambers are called atria and the lower chambers are called ventricles. The heart muscle contracts blood from chamber to chamber. With each contraction, the valves open to let blood through to the next chamber. The valves then close to stop blood from moving backward. In this way, the valves keep blood moving through the heart and out to the body. Heart Valve Problems Valve disease occurs when a valve doesn't work the way it should. If a valve doesn't open all the way, less blood can move through the smaller opening. If a valve doesn't close tightly, blood may leak backward. These problems may mean the heart has to work harder to pump the same amount of blood. Or blood may back up in the lungs or body because it's not moving efficiently through the heart.

KidsHealth Parents Medical Problems Although many parents fear the worst when their child is diagnosed with a heart murmur, it's important to know that this diagnosis is actually extremely common. In fact, many kids are found to have a heart murmur at some point during their lives. Most murmurs are not a cause for concern and do not affect the child's health at all. So what, exactly, is a heart murmur? By itself, the term heart murmur isn't a diagnosis of an illness or disorder; but to understand what it does mean, it's important to know how the heart works. The heart is divided into four chambers; two are on the left side of the heart and two are on the right. The blood returning from the body is pumped to the lungs where it's oxygenated, then pumped through the arteries to the rest of the body. After the oxygen has been used, the blood returns to the heart through the veins and is pumped through the lungs again. The word murmur describes a swishing sound made as the blood flows through any of the heart's chambers or valves or even through a hole within the heart. How Are Heart Murmurs Diagnosed?

KidsHealth Kids Kids' Health Problems You know the sound of your heartbeat: lub-dub, lub-dub. In some people, there's an extra noise that the blood makes as it flows through the heart. It sounds sort of like the noise of water flowing through a hose. This sound is called a murmur (say: mer -mer). Most murmurs don't mean anything is wrong. But sometimes they are a sign of a problem with the heart. The Heart and How It Works The heart is a strong muscle about the size of your fist that pumps blood around the body. It sits inside the chest and is protected by the rib cage. The heart has four different areas, or chambers. These chambers are connected to each other by valves that control how much blood enters each chamber at any one time. The valves open and shut with every beat. As the valves shut to control the flow of blood through the heart, they make the sound you recognize as your heartbeat. Depending on a person's age, the heart beats about 60 to 120 times every minute. Each heartbeat is really two separate sounds: lub-dub, lub-dub. Your heart goes "lub" with the closing of the valves that control blood flow from the upper chambers to the lower chambers. Then, as the valves controlling blood going out of the heart close, your heart goes "dub."

12. Congestive Heart Failure A discussion about CHF in dogs including audio of heart murmurs. http://www.petdrs.com/chf.htm

Animal Hospital of Casper - On Line Congestive Heart Failure (CHF) Congestive heart failure is one of the more common heart diseases seen in dogs, especially smaller breeds. A variety of signs may be present with CHF. This disease is normally seem in senior or geriatric age dogs. A sometimes insidious chronic cough develops over time and the pet may exhibit reduced exercise tolerance. Veterinarians must use all resources to accurately diagnose heart diseases, starting with a comprehensive physical examination and history. Below are examples of actual normal heart sounds and a heart murmur. (return to Physical exam Click on the Heart to hear actual recording of " Normal Heart Sounds and Heart Murmur "! The murmur sound is most often a result of an abnormality of the heart valves. Chronic infections, including dental disease, can cause the heart valves to become irritated and scarred for life. This diseased valves do not close tightly and, therefore, the murmur can be heard. Poor valve closure creates high blood pressure which results in retention of fluids in the lungs (sometimes the abdomen, as well). Poor circulation from the heart to the other organs (kidneys, liver and brain) can result in deterioration of those organs systems depending on good blood circulation. These pictures show the differences from a Normal heart and a CHF heart with diseased valves.

HANNON, M.D. East Carolina University School of Medicine Greenville, North Carolina A patient information handout on heart murmurs in children, written by the authors of this article, is provided on page 565. Many normal children have heart murmurs, but most children do not have heart disease. An appropriate history and a properly conducted physical examination can identify children at increased risk for significant heart disease. Pathologic causes of systolic murmurs include atrial and ventricular septal defects, pulmonary or aortic outflow tract abnormalities, and patent ductus arteriosus. An atrial septal defect is often confused with a functional murmur, but the conditions can usually be differentiated based on specific physical findings. Characteristics of pathologic murmurs include a sound level of grade 3 or louder, a diastolic murmur or an increase in intensity when the patient is standing. Most children with any of these findings should be referred to a pediatric cardiologist. (Am Fam Physician 1999;60:558-65.) P rimary care physicians frequently encounter children with heart murmurs.

19. Berger: Mitral Valve Prolapse A detailed look at mitral valve prolapse including heart murmurs, detection of heart valve abnormalities, exercise, endocarditis and prognosis among other things are discussed. Written by Christopher Berger. http://www.uoregon.edu/~iishp/Berger4.html

Mitral Valve Prolapse By Christopher Berger Introduction. Heart murmurs are abnormal heart sounds occurring due to abnormalities in one or more of the hearts four valves (1). The most common type of heart murmur is a mitral valve prolapse (MVP). Poor closure of the mitral valve and/or subsequent regurgitation of blood from the left ventricle to the left atrium causes a clicking or shuffling sound heard mid- to late-systole. MVPs are reported to be the most common valvular heart disease in industrialized countries, affecting about 3% of adults (2,3,4). MVP occurs in 6-10% of young women and 4% of young men. The prevalence may exceed 10% in women ages 14-30. Following is a brief orientation to characteristics of MVP including methods of detection, associated disorders, and treatment. Abnormal Heart Sounds (Heart Murmurs). Depending upon when they occur during the normal cardiac cycle, heart murmurs can be classified into three types: systolic, diastolic, and continuous. Brukner and Khan identify eight systolic, two diastolic, and two continuous types of murmurs (5). Fabius identifies six systolic and two diastolic types of murmurs (6). Lillegard and Rucker identify five systolic, two diastolic, and one continuous type of murmur (7). Although sources differ regarding the number of diagnosable murmurs, the classification of when the murmur occurs is critical to an appropriate diagnosis. (Systolic murmurs are typically benign and diastolic murmurs are always pathological.) MVP is classified as a systolic murmur.
