Update This publication contains information to help you understand and live a heart-healthy lifestyle. Published for friends of the Texas Heart Institute. Valve Disease Every time your heart beats, blood flows into, through, and out of your heart. In fact, your heart moves about 100 gallons (379 liters) of blood through your body every hour. Blood is pumped through your heart in only one direction. Heart valves play key roles in this one-way blood flow, opening and closing with each heartbeat. Pressure changes behind and in front of the valves allow them to open their flap-like "doors" (called cusps or leaflets) at just the right time, then close them tightly to prevent a backflow of blood. There are 4 valves in the heart: Tricuspid valve Pulmonary valve Mitral valve Aortic valve Blood without oxygen returns from the body and flows into the heart's upper-right chamber (the right atrium). From there, it is forced through the tricuspid valve into the lower-right chamber (the right ventricle). The right ventricle pumps the blood through the pulmonary valve and into the lungs. While in the lungs, the blood picks up oxygen. As the right ventricle is preparing to push blood through the pulmonary valve, the tricuspid valve closes to stop blood from flowing back into the right atrium.

Aortic stenosis is the narrowing or obstruction of the heart's aortic valve, which prevents it from opening properly and blocks the flow of blood from the left ventricle to the aorta. Causes, incidence, and risk factors Return to top Aortic stenosis is caused by many disorders. One common cause is rheumatic fever , a complication of untreated strep throat. Other causes include calcification of the valve and congenital abnormalities (disorders present at birth). There may be a history of other valve diseases, coronary artery disease , or heart murmur.

//var DOCUMENTGROUP=''; //var DOCUMENTNAME=''; //var ACTION=''; Heart Information Center Types of Valve Disease Diseases of the heart valves are grouped according to which valve or valves are involved and the amount of blood flow that is disrupted by the problem. The most common and serious valve problems happen in the mitral and aortic valves. Diseases of the tricuspid and pulmonary valves are fairly rare. Diseases of the Mitral Valve Mitral Valve Prolapse The mitral valve regulates the flow of blood from the upper-left chamber (the left atrium) to the lower-left chamber (the left ventricle). Mitral valve prolapse (MVP) means that one or both of the valve flaps (called cusps or leaflets) are enlarged, and the flaps' supporting muscles are too long. Instead of closing evenly, one or both of the flaps collapse or bulge into the atrium. MVP is often called click-murmur syndrome because when the valve does not close properly, it makes a clicking sound and then a murmur. What causes MVP?

What causes aortic stenosis? How does aortic stenosis affect the left ventricle pump? How do patients with aortic stenosis feel? ... Aortic Valve Stenosis At A Glance What is aortic stenosis? The heart is a muscular pump with four chambers and four heart valves. The upper chambers, the right atrium and left atrium (atria - plural for atrium), are thin walled filling chambers. Blood flows from the right and left atria across the tricuspid and mitral valves into the lower chambers (right and left ventricles). The right and left ventricles have thick muscular walls for pumping blood across the pulmonic and aortic valves into the circulation. Heart valves are thin leaflets of tissue which open and close at the proper time during each heart beat cycle. The main function of these heart valves is to prevent blood from flowing backwards. Blood circulates through the arteries to provide oxygen and other nutrients to the body, and then returns with carbon dioxide waste through the veins to the right atrium. When the ventricles relax, blood from the right atrium passes through the tricuspid valve into the right ventricle. When the ventricles contract, blood from the right ventricle is pumped through the pulmonic valve into the lungs to reload on oxygen and remove carbon dioxide. The oxygenated blood then returns to the left atrium and passes through the mitral valve into the left ventricle. Blood is pumped by the left ventricle across the aortic valve into the aorta and the arteries of the body.

Online Resources Maryland Heart Center Valvular Disease Valve Disease Overview Aortic Valve Disorders Mitral Valve Disorders Aortic Valve Repair and Replacement Mitral Valve Repair and Replacement Valvular heart disease occurs when the heart's valves no longer help regulate blood flow. The human heart contains four one-way valves that assure efficient unidirectional blood flow through the lungs and the systemic circulation. The two valves that most commonly become diseased and are responsible for the vast majority of clinical heart valve disease are the inlet (mitral) and outlet (aortic) valves of the main pumping chamber of the heart, the left ventricle. The valve may have a defect such as artificial narrowing (stenosis) which restricts blood flow, or may be weakened and cause regurgitation (where the blood is re-directed in the wrong direction). This disease may be caused by damage to the heart muscle as a result of rheumatic fever or a congenital abnormality. Over time, valve disease can cause the heart muscle to become overworked, and if left untreated can cause even further damages. Anatomy of the Valves Click on image for more information The mitral valve is the inflow valve to the left ventricle and is positioned between the left atrium, which receives blood from the lungs and the left ventricle. The mitral valve opens during relaxation of the left ventricle (diastole) and allows blood from the atrium to fill the ventricle. Contraction of the ventricle (systole) causes a rapid increase of pressure in the ventricle, which in turn results in closure of the mitral valve.

Online Resources Maryland Heart Center Aortic Valve Disorders Valve Disease Overview Valve Disease Mitral Valve Disorders Aortic Valve Repair and Replacement Mitral Valve Repair and Replacement The normal aortic valve consists of three leaflets. There are two ways that the aortic valve can malfunction. A stenotic (narrowed) aortic valve does not fully open as a result of disease affecting the ability of the valve leaflets to open, and an obstruction to the outflow of blood from the left ventricle is created. In contrast, an insufficient aortic valve leaks, and allows backflow of blood from the aorta to the left ventricle during diastole. Asymptomatic patients with aortic stenosis or aortic insufficiency have a good prognosis. Once symptoms develop, the prognosis becomes poor and operation is usually performed. Aortic stenosis is the most common reason for heart valve surgery. Causes The two most common causes of aortic stenosis in North America are degenerative calcification of the aortic valve and a congenital bicuspid aortic valve. Degenerative calcific aortic stenosis is a disease of aging and will become increasingly common as the United States population ages. The presence of obstruction to ventricular outflow causes hypertrophy (enlargement) of the left ventricular myocardium (heart muscle), which compensates for the outflow obstruction.

To understand this condition, it's helpful to know how the aortic valve normally functions. The aortic valve works like a one-way gate, opening so that blood from the left ventricle (the heart's main pump) can be pushed into the aorta , the large artery leaving the heart. From the aorta, oxygen-rich blood flows into the branching arteries and through the body to feed the cells. When the heart rests between beats, the aortic valve closes to keep blood from flowing backward into the heart. See an illustration of

Heart Guide Vascular Guide History of Innovations About Us ... Dictionary Treating the Heart, Blood Vessels and Circulation There are many types of valve disease. There are those that are developed before birth (congenital) or those which are acquired. Sometimes the cause of valve disease may be unknown. The most common types of valve disease include: Congenital valve disease (bicuspid aortic valve) Acquired valve disease: myxomatous valve disease ( mitral valve prolapse) degenerative calcification infection (rheumatic valve disease, endocarditis) Other causes of valve disease include : coronary artery disease, heart attacks, cardiomyopathy (heart muscle disease) , syphilis, hypertension, aortic aneurysms, connective tissue diseases, and less commonly, tumors, some types of drugs and radiation. Congenital valve disease means your valves are not formed correctly before birth. Valves may be the wrong size, have malformed leaflets, or have leaflets that are not attached to the annulus correctly; this most often affects the aortic or pulmonic valve. Bicuspid aortic valve is the most common type of congenital valve disease. Instead of the normal three leaflets or cusps, the bicuspid aortic valve has only two. Without the third leaflet, the valve may be:

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?
