Extractions: One of the rites of passage that medical students must go through to earn their white coat is to spend many hours listening down the stethoscope to their patient's heart beating. At first it's little more than a fuzzy strain on the ear but with perseverance you get to recognise all sorts of whistles, clicks and whirs as the heart goes about its pumping job. It's an essential skill because some of those noises spell out disease, especially of the heart valves. One noise, which many people have heard about, is a murmur. This is simply a sound created by the flow of blood. It may be normal (for example after heavy exercise anyone may develop a murmur due to increased blood flow.) Or it may be highly specific for a certain heart valve problem, allowing experts to diagnose defective heart valves after just a quick listen to the heart. I've painted a rather old fashioned scene, because these days not only does the medical school curriculum cover a much more diverse range of skills and approaches to diagnosis, but also one of the main causes of heart valve disease - Rheumatic fever - is very rare now. However, a report at a recent meeting of the

Extractions: Rheumatic fever is a clinical syndrome of poorly understood pathogenesis, which affects multiple organ systems. It only occurs following pharyngeal infection with Lancefield group A ß-hemolytic streptococci, although the reason for this association is still unknown. The mechanism may include cross-reactivity between streptococcal components and human connective tissue elements, or possibly modification of self antigens by streptococcal infection. More recently, streptococcal M proteins have been implicated; these are proteins which act as 'superantigens' and nonspecifically stimulate whole populations of T cells. In the acute phase, rheumatic fever may present with CNS involvement (Sydenham's chorea), polyarticular arthritis, skin changes, and carditis. Rheumatic carditis is a pancarditis , which means that all the layers of the heart are involved - endocardium, myocardium, and pericardium. The microscopic lesion of acute rheumatic carditis is the Aschoff nodule (see Image 31 [~336 kb] and Description ), a collection of lymphocytes and histiocytes which is most easily found in the fibrous interstitial septa of the myocardium. Fibrinous pericarditis ("bread-and-butter" pericarditis) may occur and give rise to a frictions rub. In the acute phase, involvement of the heart valves may lead to wart-like raised fibrinous lesions ("verrucae") on the closure line of the valve cusps.

Extractions: tricuspid regurgitation By Eric Berlin, MD Tricuspid regurgitation occurs when the tricuspid valve within the heart fails to close tightly. This causes blood to flow backward. What is going on in the body? There are four chambers in the heart, two on the left side and two on the right. The tricuspid valve separates the upper and lower chambers on the right side of the heart. Failure of this valve to close properly may lead to circulation problems and damage to the heart over time. What are the signs and symptoms of the disease? Many people with triscuspid regurgitation have no symptoms. If symptoms do occur, they may include: fatigue cold skin palpitations , or an unusual awareness of the heartbeat shortness of breath abdominal distress swollen veins in the neck swelling in the legs What are the causes and risks of the disease? This condition has many causes, including: congenital heart disease , in which the infant is born with an defective tricuspid valve congestive heart failure a heart attack pulmonary hypertension, or high blood pressure in the arteries that carry blood through the lungs rheumatic fever , a condition that may occur as a complication of strep throat infection of the heart valves, called endocarditis. A person who uses intravenous drugs, such as heroin, is at a high risk for this cause of tricuspid valve damage.

Extractions: By Lori Siemens, DVM, DACVIM Posted with the permission of the author. Tricuspid valve dysplasia (TVD) is a congenital, heritable heart defect that seems to be increasing in prevalence in Labrador Retrievers. The tricuspid valve is one of four heart valves and allows blood to flow in one direction from the right atrium into the right ventricle. If a puppy inherits the gene (or genes) responsible for the defect, its tricuspid valve will be malformed in utero. The medical term for malformation of a valve is dysplasia. Thus, the puppy will have a dysplastic valve at birth that does not shut tightly, allowing blood to leak (regurgitate) back through it. The size of the leak will dictate the severity of the disease. A puppy with mild regurgitation will likely have a normal life span. If the regurgitation is severe, the puppy may not live to see its first birthday. Severe TVD causes the right side of the heart to progressively enlarge. The blood leaking backwards into the right atrium eventually causes the pressure inside this chamber to rise. Since veins returning from the liver connect to the right atrium, the pressure in the veins of the liver also increases. The high venous pressure causes fluid to ooze from these liver vessels which then accumulates in the abdominal cavity. This fluid is termed ascites and is a form of congestive heart failure. The onset of ascites indicates advanced, end-stage cardiac disease. Medications can help palliate the symptoms, but it is considered a terminal condition.

http://www.askaheartsurgeon.com/leaky valve.htm

Extractions: Heart Valves It is clear from these figures that a valve that has a small opening because of disease (ie: rheumatic fever) will impede the flow of blood through the heart. Over time this will cause the top chamber of the heart (usually the left atrium in the case of mitral valve disease) to become enlarged. Sometimes the heart will develop atrial fibrillation as a result of the enlarged left atrium. (see figure below, on left). Atrial fibrillation is a type of irregular heart beat. Click here to learn more about this irregular heart beat. Similarly, a valve whose opening is too wide and is not able to stop the backward flow of blood when it attempts to close, is insufficient. This will result in less foward flow through the heart since a large amount of blood is pushed backwards toward the top chamber, the left atrium, (see figure below on right).

Extractions: Heart Valve Disease The four valves of the heart are made up of two or three very strong flaps of tissue, called leaflets, that open and close as the heart contracts and relaxes. When working properly, these leaflets keep blood flowing in the right direction in the heart. But when they do not work properly, a number of conditions can occur, and these conditions can cause heart valve disease. Although there are many different types of heart valve disease, the primary ones are: Stenosis This happens when a valve opening becomes narrowed or does not form properly. Regurgitation This occurs when a valve fails to close completely, causing some blood to leak backward instead of flowing forward. Regurgitation is also known as insufficiency. Sclerosis Sclerosis is a thickening of the valve itself which causes the valve to become restricted.

http://www.tcg.cardiologydomain.com/images/uploaded/TCG/Mitrial.cfm

Extractions: Mitral Valve Disease The heart is a muscular pump divided into four chambers. Two thin-walled chambers, the left atrium and right atrium, form the upper part of the heart. The other chambers, the left and right ventricles, are the hearts main blood-pumping chambers and form the bottom part of the heart. The right atrium receives blood as it returns to the heart from the veins from different parts of the body and transports blood to the right ventricle, and the left atrium receives oxygenated blood from the lungs and transports it to the left ventricle. The right ventricle pumps blood into the lungs to be oxygenated, while the left ventricle pumps blood to the rest of the body to deliver the oxygen. The valves in the heart affect the way that blood flows through the chambers of the heart. There are two valves on the right side of the heart, the tricuspid and pulmonary valves, and two valves on the left side of the heart, the mitral and aortic valves. These valves resemble flaps, and each valve is made up of segments or leaflets. The valves open and close to keep blood flowing through the heart in only one direction. The tricuspid valve separates the right atrium and right ventricle. When the heart beats, the tricuspid valve is pushed shut, preventing blood from flowing backward from the right ventricle into the right atrium. When the heart relaxes, the tricuspid valve opens, allowing blood from the right atrium to fill the right ventricle. When the heart beats, the pulmonary valve is pushed open, allowing blood to flow into the lung arteries. When the heart relaxes, the pulmonary valve closes, preventing blood from flowing backward into the right ventricle.

Other valve deformities are not acquired until later in life. Conditions such as an infection can invade or damage the vaIve leaflets or doors. The natural aging process may weaken already damaged valve leaflets or harden normal valve tissue. Valve problems produce many symptoms. Faulty heart valves can cause dizziness, shortness of breath, fatigue, irregular heart beats, fluid buildup, strokes and heart attacks. Tests such as an echocardiogram or a cardiac catheterization can show if heart valves are damaged or not functioning properly.

TRICUSPID VALVE The tricuspid valve has three main cusps and is situated between the right atrium from the right ventricle. The right atrium receives blood returning from the body and pushes the blood into the right ventricle. As the right and left ventricles relax during the diastolic phase of the heartbeat, the tricuspid valve opens, allowing blood to enter the ventricle. During the systolic phase of the heartbeat, both blood-filled ventricles contract, pumping out their contents, while the tricuspid and mitral valves close to prevent any backflow.
