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.

42. Mitral Valve Disease the most common form of valvular heart disease in the States, the flaps of the mitralvalve may protrude right side of the heart, the tricuspid and pulmonary http://www.wiheart.cardiologydomain.com/images/uploaded/WiscHeart/MVD.cfm

Basic Facts A normal mitral valve opens wide to allow blood from the left atrium to flow into the left ventricle and closes tightly as blood is pumped out of the left ventricle. Mitral stenosis is a narrowing or obstruction of the mitral valve that prevents the valve from opening properly, and mitral regurgitation means that the mitral valve does not close fully, allowing blood to flow backwards into the atrium when the left ventricle contracts. In mitral valve prolapse, the most common form of valvular heart disease in the United States, the flaps of the mitral valve may protrude or billow back into the left atrium. 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 heart’s 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.

43. Aortic Valve Disease When the heart relaxes, the tricuspid valve opens, allowing blood from the rightatrium But when aortic valve disease is present, the valve no longer opens or http://www.wiheart.cardiologydomain.com/images/uploaded/WiscHeart/AVD.cfm

Basic Facts A normal aortic valve opens wide to allow blood to be pumped from the heart to the rest of the body and closes tightly to prevent blood from flowing back into the heart. Aortic stenosis is a narrowing or obstruction of the aortic valve that prevents the valve from opening properly, impeding the flow of blood from the heart’s left ventricle into the aorta. Aortic regurgitation occurs when the aortic valve does not close properly between heartbeats, allowing blood to regurgitate, or spill back, from the aorta into the left ventricle. 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 heart’s 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 between these chambers affect the way that blood flows through 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.

Appointment Heart Valve Diseases What are heart valves? The heart consists of four chambers, two atria (upper chambers) and two ventricles (lower chambers). 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: tricuspid valve - located between the right atrium and the right ventricle pulmonary valve - located between the right ventricle and the pulmonary artery mitral valve - located between the left atrium and the left ventricle aortic valve - located between the left ventricle and the aorta How do the heart valves function?

Kouchoukos, M.D. Missouri Baptist Medical Center, St. Louis, Missouri What is heart valve disease? The heart has four valves. When the heart muscle contracts, the valves prevent blood from flowing in the reverse direction. Some people are born with a structural abnormality of a heart valve, called a congenital disorder. Some people may have an acquired heart valve disorder, caused by diseases such as rheumatic fever, infection or inflammation, which can damage heart valves and interfere with heart valve function. When heart valves are diseased, two major problems can develop: the valves leak, causing the blood to flow in the reverse direction from normal, or the valves become narrow (stenosis) as scar tissue and calcium deposit on the valve and interfere with the normal forward blood flow. Some valves may develop both stenosis and leakage. Which heart valves are involved?

Encyclopedia Index T Home Encyclopedia Encyclopedia Index T Tricuspid valve insufficiency Definition Tricuspid valve insufficiency occurs when a tricuspid valve does not close tightly enough to prevent leakage. This condition is also called tricuspid valve regurgitation and tricuspid incompetence. Description The tricuspid valve is located between the right atrium and the right ventricle of the heart. When the right ventricle contracts, it is supposed to pump blood forward into the lungs. If the tricuspid valve does not close tightly, some of that blood leaks back into the right atrium. When the atrium receives its usual quantity of blood from veins leading to the heart, plus the leaking blood, the pressure inside the atrium increases. This higher pressure creates resistance to the flow of blood in the veins that enter the atrium from the body. In addition, this increase in pressure causes the right atrium to enlarge over time. Congestion from fluid buildup occurs, particularly in the liver and legs. Causes and symptoms If a person has serious lung disease or a narrowing of the pulmonary valve, the right ventricle must pump harder to force the blood through the pulmonary valve. In order to pump harder, the right ventricle enlarges and the valve opening stretches, causing the valve to leak.

Heart Valve Disease (Valvular Heart Disease) Heart valve disease (valvular heart disease) is the name given to any dysfunction or abnormality of one or more of the heart's four valves, including the mitral and aortic valves on the left side, and the tricuspid and pulmonic valves on the right side. The two main types of valvular disease, regurgitation (leaking) and stenosis (narrowing) of the valves. 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. There are a number of different types of valvular diseases. Valvular stenosis is a condition in which there is a narrowing, stiffening, thickening, fusion or blockage of one or more cardiac valves. Depending on which area is affected, the patient will be diagnosed with aortic stenosis, mitral stenosis, pulmonic stenosis or tricuspid stenosis. Valvular regurgitation is a condition in which blood leaks back in the wrong direction because one or more of the cardiac valves is closing improperly. Depending on the area affected, the patient will be diagnosed with aortic regurgitation, mitral regurgitation, pulmonary regurgitation or tricuspid regurgitation. Valvular atresia is a serious condition in which one of the valves has failed to develop properly and is completely closed at birth. Depending on which area is affected, the patient will be diagnosed with aortic atresia, mitral atresia

Usually tricuspid regurgitation can be fixed with one of several different repair techniques. The symptoms produced by severe tricuspid regurgitation include fatigue, shortness of breath, fluid retention, ankle edema, and abdominal swelling. Untreated tricuspid regurgitation, if severe, can often times lead to liver damage. At the time of surgery, if other valves are being replaced or repaired and there are symptoms of tricuspid regurgitation, the tricuspid valve should be fixed, as well.

There are four valves in the heart. Blood in the heart is pumped in only one direction and the heart valves regulate this flow. Pressure changes around the valves cause them to open and close their cusps or leaflets which are flap-like structures, at the correct time and then close them tightly to prevent backflow of blood. The four valves are: The tricuspid valve The pulmonary valve The mitral valve The aortic valve The oxygen-rich blood returning from the lungs flows into the upper-left chamber (the left atrium). From here, the blood flows through the mitral valve into the lower-left chamber (the left ventricle) and the mitral valve then closes to prevent backflow of blood. The left ventricle then pushes the blood through the aortic valve, into the aorta (the largest artery in the body) and so to the rest of the body.

Mitral Valve Disease in Cavalier King Charles Spaniels The following article has been provided by Dr Russell Mitten, BVSc DVR (Consultant), who addressed the Club's General Meeting on the 15th February 2000. What is it? What goes wrong? Over a period of time we see progressive deterioration of the heart valves. The most commonly affected is the mitral valve, on the left side, followed by the tricuspid valve (on the right)and the aortic valve (on the left). The normal flexible thin valve leaflets become gnarled, fibrous and thickened, and their restraining tendons also thicken and sometimes rupture. The result is an incompetent leaky valve which allows progressively more and more backflow. Eventually up tp 80% of the output from the heart is leaking back through the valve (termed regurgitation) and only 20% is moving forward. As a result, the heart chambers enlarge, the heart muscle works harder and eventually the muscle may fail. In some cases, the thin-walled atrial chambers may rupture, and in others the valve tendons give way, both having disastrous (ie fatal) consequences. What are the signs?

Symptoms of valve disease. http://www.texheartsurgeons.com/Valves.htm

Heart Valve Diseases and Heart Valve Surgery Heart valves have key roles in regulating blood flow through the heart, opening and closing in sequence with each heartbeat. These valves act like one-way doors, allowing blood to flow either forward into the next chamber, or out of the heart via one of two main blood vessels that carry blood away from the heart. The valves close to prevent back flow. Heart Valve Functions On the right side of the heart, blood flows through the tricuspid valve, which lies between the right atrium and the right ventricle. On the left side of the heart, the mitral valve controls the blood flow between the left atrium and left ventricle. The pulmonary valve controls flow from the right ventricle into the pulmonary artery , which carries blood to the lungs for oxygenation. On the left side, the aortic valve opens the way for oxygenated blood to pass from the left ventricle into the aorta , the body?s largest artery. Causes of Heart Valve Malfunction Heart valves may become impaired for a variety of reasons. Rheumatic fever, the most common cause of valve malfunction, causes a valve to stiffen over time. This limits the ability of the valve to open and close properly. Some people are born with heart valve abnormalities, which may be corrected at birth or later in life. Other people may acquire valve damage from infection (as with bacterial endocarditis) or other diseases. The results are a tight, rigid valve limiting forward blood flow (called a stenotic valve ), or a valve which does not close properly, permitting back flow (called a
