The tricuspid valve regulates the opening between the right atrium and the right ventricle. As the right atrium contracts, the tricuspid valve opens, allowing blood to eject into the right ventricle. When the atrium is finished contracting, the tricuspid valve closes, thereby preventing a backwash of blood ("regurgitation") into the right atrium.

In a normally functioning heart, the four valves (flaps made of tissue) keep blood flowing in one direction and only at the right time. They act as gates that swing open to allow blood to flow through and then tightly shut until the next cycle begins. According to the 2004 Heart and Stroke Statistical Update , valvular heart disease is responsible for nearly 20,000 deaths each year in the United States and is a contributing factor in about 42,000 deaths. The majority of these cases involve disorders of the aortic valve (63 percent) and the mitral valve (14 percent). Deaths due to pulmonic and tricuspid valve disorders are more rare (0.06 percent and 0.01 percent, respectively).

Living with valve disease According to the American Heart Association, about 5 million Americans are diagnosed with valvular heart disease each year. What Is Valvular Heart Disease? Heart valve disease occurs when your heart's valves do not work the way they should. How Do Heart Valves Work? Your heart valves lie at the exit of each of your four heart chambers and maintain one-way blood flow through your heart. The four heart valves make sure that blood always flows freely in a forward direction and that there is no backward leakage. Blood flows from your right and left atria into your ventricles through the open mitral and tricuspid valves. When the ventricles are full, the mitral and tricuspid valves shut. This prevents blood from flowing backward into the atria while the ventricles contract (squeeze). As the ventricles begin to contract, the pulmonic and aortic valves are forced open and blood is pumped out of the ventricles through the open valves into the pulmonary artery toward the lungs, the aorta, and the body.

The valves allow blood to flow in one direction only Each heart valve is a set of flaps or cusps that open or close to control the flow of blood through the heart and its chambers. The valves allow blood to flow in one direction only; if blood flows the other way, they're forced shut. There are four chambers in the heart and four heart valves to control blood flow between them. The tricuspid valve controls blood flow from the right atrium into the right ventricle. The pulmonary valve controls blood flow out of the right ventricle into the pulmonary artery (into the lungs). The mitral valve controls blood flow from the left atrium into the left ventricle.

Case Studies In Small Animal Cardiovascular Medicine Case 9 Text from "Small Animal Cardiovascular Medicine" MYXOMATOUS ATRIOVENTRICULAR VALVULAR DEGENERATION INTRODUCTION PATHOLOGY Myxomatous degeneration primarily affects the mitral and tricuspid valve leaflets and the chordae tendineae. Mitral valve lesions are more common. In about 60% of cases the mitral valve alone is affected while only the tricuspid valve is affected in about 10% of cases. The other 30% have both valves involved. The disease only rarely affects the aortic and pulmonic valves. Besides the valvular and chordal changes, the left atrium is dilated and the left ventricle is eccentrically hypertrophied. Jet lesions are commonly seen in the left atrium. They are fibrous plaques in the endocardium that occur in a region subjected to the impact of the high velocity mitral regurgitant jet. Endomyocardial splits or tears may also be identified. On occasion, a full thickness left atrial tear occurs resulting in hemopericardium, pericardial tamponade, and, usually, death. Rarely, a full thickness endomyocardial tear will involve the interatrial septum, causing an acquired atrial septal defect. Intramural coronary arteriosclerosis has been reported in dogs with chronic myxomatous mitral valve degeneration and has been used as an explanation for myocardial failure in this disease. This type of lesion is also observed in older dogs without mitral valve disease suggesting it is an incidental finding.

The Endocardium Infective Endocarditis. Infective endocarditis can produce a very wide spectrum of clinical signs, as bacteria released from the infected valve enter the circulation and colonize other organs. There may be neurologic, gastrointestinal, urologic, orthopedic, and cardiovascular clinical signs. A chronic, fluctuating fever is usually present. Shifting leg lameness may occur. Malaise and weight loss are present in almost all cases. If a right-sided valve is affected (tricuspid, pulmonic), then ascites and jugular pulsations may be present. A murmur will be present in most cases, the exact type depending on the valve involved. When there is aortic endocarditis, a soft diastolic murmur will be present, heard best over the left heart base, and arterial pulses will be bounding. Mitral endocarditis will result in a murmur very similar to that caused by degenerative valve disease, i.e. a prominent systolic murmur heart best over the left cardiac apex. Bacteria most often isolated from affected small animals include Streptococcus, Staphylococcus, E. coli, and Klebsiella. Other bacterial species and fungi may be involved. A precipitating infection (dental disease, pyoderma, prostatitis) can be determined in approximately 60% of affected dogs. Streptococcus and Actinobacillus equuli are the most common isolates of horses. A complete blood count often shows a neutrophilic leukocytosis. An active infection may be associated with the presence of band neutrophils, and a chronic disease with a monocytosis (90% of cases in one series). Anemia of chronic disease is frequently present.

There are four chambers of the heart, two on the right side and two on the left. The upper chamber on the right side (right atrium) receives blood returned from various parts of the body and then empties to the right lower chamber (right ventricle). There is a valve between the right atrium and the ventricle, called tricuspid valve . This valve allows emptying of blood from the right atrium into the right ventricle and then closes to prevent the return of blood back into the right atrium. The other heart valves to be described later have similar functions i.e. regulating forward blood flow and preventing backward return. The right ventricle pumps the blood into the lungs where it gets oxygen. The blood here goes through another valve called the pulmonary valve .The blood is received by the left upper chamber (atrium) after it has received oxygen in the lungs. Then the left atrium empties the blood into the left lower chamber (ventricle) via a valve called the mitral valve . Finally, the blood is pumped from the left lower chamber (ventricle) to various parts of the body for supplying oxygen. The blood leaves the left ventricle via another valve called the

The heart has two halves, a left and a right, each with two chambers - the atrium and the ventricle. Between the chambers are the heart valves which ensure the blood runs only in one direction. There are also heart valves situated between the ventricles and the major arteries - the aorta and pulmonary artery - where they have the same function. Failure in a valve in the left side of the heart - the aortic or the mitral valve - results in left-sided heart failure . This leads to an accumulation of fluids in the lungs, or pulmonary oedema.

On this page: Wikipedia Mentioned In Or search: - The Web - Images - News - Blogs - Shopping heart valve Wikipedia heart valve In anatomy , the heart valves are valves in the heart that prevent blood from flowing the wrong way. There are four valves of the heart: Two atrioventricular (AV) valves - ensure blood flows from the atria to the ventricles, and not the other way. Two semilunar valves - these are present in the arteries leaving the heart, and they prevent blood flowing back from the artery into the ventricle. Heart valves open and shut depending on the difference in pressure on each side. The sound of the heart valves shutting causes the heart sounds AV valves These are large, multicusped valves that prevent backflow from the ventricles into the atria during systole . They are anchored to the wall of the ventricle by chordae tendinae , that prevent the valve from inverting. The chordae tendinae are attached to papillary muscles that cause tension to better hold the valve. Together, the papillary muscles and the chordae tendinae are known as the subvalvular apparatus. The function of the subvalvular apparatus is to keep the valves from prolapsing into the atria when they close. The subvalvular apparatus have no effect on the opening and closure of the valves, however. This is caused entirely by the pressure gradient across the valve. Mitral valve Also known as the bicuspid valve , the mitral valve gets its name from the resemblance to a

Davol, 76 Mildred Avenue, Swansea, MA 02777-1620 pdavol@labbies.com Tricuspid Valve Dysplasia in the Labrador Retriever WHAT IS TRICUSPID VALVE DYSPLASIA (TVD)? To understand tricuspid valve dysplasia (TVD), it is first important to know a bit about the anatomy of the canine heart. The canine heart, like the human heart, is divided into two halves. The right side of the heart receives oxygen depleted blood from the tissues of the body and pumps this blood into the lungs through the pulmonary artery. After becoming oxygenated in the lungs, the blood returns to the left side of the heart through the pulmonary veins where it is then pumped to the tissues of the body by way of the aorta. Each half of the heart is subdivided into an upper and lower chamber. The upper chamber, called the atrium, receives the blood and then passes the blood to the lower chamber called the ventricle. The ventricle then pumps the blood to its destination. To prevent backflow of the blood from the ventricle to the atrium, the heart is equipped with valves that allow blood to flow in only one direction. There are two atrioventricular valves which control blood flow between the atria and the ventricles: the tricuspid valve which is located between the right atrium and right ventricle and the mitral valve which is located between the left atrium and left ventricle. In the canine, the tricuspid valve is made up of two irregularly shaped flaps composed of connective tissue. The tissue of the flaps is connected to the papillary muscle of the ventricle by tendon-like cords called chordae tendineae. As the right atrium contracts, blood passes through the tricuspid valve into the right ventricle. When the ventricle contracts, some blood flows backward, pushing upward against the flaps of the valve causing them to meet and form a barrier which prohibits the blood from re-entering the upper chamber. The chordae tendineae prevent the flaps from opening backward into the atrium which would break the seal and thus allow backflow of the blood.

There is a valve through which blood passes before leaving each chamber of the heart. The valves prevent the backward flow of blood. These valves are actual flaps that are located on each end of the two ventricles (lower chambers of the heart). They act as one-way inlets of blood on one side of a ventricle and one-way outlets of blood on the other side of a ventricle. Each valve actually has three flaps, except the mitral valve, which has two flaps. The four heart valves include the following:

DCI Home Congenital Heart Defects : What Is ... What Is ... Other Names How the Heart Works Causes ... Links What is a Congenital Heart Defect? The term "congenital heart defect" indicates that a structural problem (or defect) in a baby's heart is present at birth. A baby's heart begins to form shortly after conception. By the end of the 2nd month of pregnancy, the baby's heart is completely formed. It is during this time that a congenital heart defect can occur. In this case, a part of the heart, heart valves, and/or blood vessels near the heart do not develop properly. When this happens, blood flow can: Slow down Go in the wrong direction or to the wrong place Be blocked completely. Congenital heart defects are the most common type of major birth defect. More than 30,000 babies are born with a congenital heart defect in the United States each year. Types of Congenital Heart Defects There are many types of congenital heart defects. They are: Abnormal passages in the heart or between blood vessels Problems with the heart valves Problems with the placement or development of blood vessels near the heart Problems with development of the heart itself.
