MITRAL VALVE DISEASE AND HEART FAILURE IN DOGS What is the mitral valve? The heart has four chambers. The upper chambers are called atria (singular: atrium), and the lower chambers are called ventricles. The heart is also divided into right and left sides. Blood flows from the body into the right atrium. It is stored there briefly then pumped into the right ventricle. The right ventricle pumps blood into the lungs where it receives oxygen. It flows from the lungs into the left atrium where it is held a few seconds before going into the left ventricle. The left ventricle is surrounded by the largest and strongest of the heart muscles. This large muscle is necessary to pump blood to all parts of the body. Each side of the heart has a valve to keep blood from going backward from the ventricles to the atria. The valve between the left atrium and left ventricle is called the mitral valve. Because of the very large pressure created when the left ventricle contracts, the mitral valve wears out in many dogs. This wearing out process begins with a small leak that gradually gets more severe. How common is mitral valve disease?

What Are The Results of Mitral Valve Repair? ... What Will My Condition Be Like After Mitral Valve Repair? INTRODUCTION Mitral valve repair is an open heart procedure performed by cardiothoracic surgeons to treat stenosis (narrowing) or regurgitation (leakage) of the mitral valve . The mitral valve is the "inflow valve" for the left side of the heart. Blood flows from the lungs, where it picks up oxygen, and into the heart through the mitral valve. When it opens, the mitral valve allows blood to flow into the heart's main pumping chamber called the left ventricle. It then closes to keep blood from leaking back into the lungs when the ventricle contracts (squeezes) to push blood out to the body. It has two flaps, or leaflets. The mitral valve is highlighted on this illustration of a heart. The mitral valve is the "inflow valve" for the left side of the heart.

Mitral valve is a heart valve, which is composed of two leaflets (anterior and posterior) demarcated by two commissures along an annular ring, separating the left atrium from the left ventricle, and serving as a door and guard for the entrance of blood either from the left atrium or abnormally from the left ventricle due to regurgitation. It opens and closes to allow oxygenated blood to flow from the left atrium into the left ventricle (see figures ). Its leaflets are attached distally by fibrous strands called chordae tendineae to papillary heart muscles in the cavity of the left ventricle. click to enlarge click to enlarge click to enlarge click to enlarge ... click to enlarge This valve's orifice or door may become too narrow (stenosis, see figure 20a, 20b, 20c, 44a, 44b, 44c, 44d, 44e) due to rheumatic fever sequelae or congenital heart disease including the rare deformity of the "parachute" mitral valve (figure 44 g-1 and figure ) or too wide to close properly (regurgitation, see figure 45, 69, 109, 118) due to various diseases, such as myocardial infarction (heart attack, see definition of

Valve Surgery Options Introduction Approximately 70,000 heart valve replacement procedures are performed annually in the United States for conditions ranging from Mitral Valve Stenosis resulting from rheumatic fever, Mitral Regurgitation from "floppy" valves, and Calcified Aortic Stenosis encountered in large numbers of aging patients, particularly elderly women. Mitral Valve Stenosis Mitral valve stenosis occurs predominantly in women. The reasons for this are unknown but it has been documented in virtually every clinical series about the disease since the turn of the century. The incidence of rheumatic disease has markedly decreased in the United States due to better prophylaxis treatment of streptococcal infections with the use of antibiotics. Paradoxically, the treatment of mitral valve stenosis may be increasing. The reasons are related to immigration and the incidence of rheumatic heart disease in third-world countries. Immigrants from southeast Asia and South and Central America currently comprise a large number of patients in the United States with rheumatic heart disease. Mitral Regurgitation Mitral valve regurgitation (also referred to as mitral valve prolapse or MVP) follows a very different path for a woman versus a man. The condition of mitral valve prolapse is commonly diagnosed in young females yet the incidence in elderly women decreases markedly. Conversely, there is a fairly consistent incidence of mitral prolapse in the male population at both young and old age. Recent studies have indicated that, for men, the incidence of mitral prolapse requiring surgical intervention is higher than for women and it increases with age (Wilcken DEL, HickeyAJ Liftime: Risk for patients with mitral valve prolapse of developing severe valve regurgitation requiring surgery.

Mitral valve disease The mitral valve separates the left atrium and the left ventricle of the heart and is a fibrous structure lined by endocardium. There is the mitral annulus, the leaflets that are a large anterior or aortic leaflet and a small posterior or mural leaflet, the chordae tendineae and the papillary muscles. Abnormalities in any of these structures can cause mitral valve dysfunction. The leaflets are tethered to the left ventricle by the chordae tendineae. Chordae tendineae are attached to papillary muscles and prevent prolapse of the mitral valve leaflet to prevent reflux of blood into the left atrium. Obstruction to flow through the valve is mitral stenosis. Regurgitation when the valve should be preventing reflux is variously called mitral insufficiency, incompetence and regurgitation. It may be argued that a stenotic valve is also insufficient or incompetent and so perhaps regurgitation is to be preferred. In addition, the chordae tendinae may fail to hold the valves shut as they should allowing mitral prolapse. Any of these three conditions can occur alone or in combination. Epidemiology Aetiology Disease of the valve may be congenital or acquired. Historically much mitral valve disease has been post-rheumatic but with the decline of

A B C D ... W MITRAL VALVE DISEASE What is Mitral Valve Disease ? Why does Mitral Valve Disease occur ? Mitral stenosis is caused by rheumatic fever which is now rare. Mitral regurgitation can also be caused by rheumatic fever but there are other causes too. Diseases of the left ventricle may affect the valve by damaging the papillary muscles or altering the valve structure. Coronary artery disease (due to hardening of the arteries) may do this by causing a heart attack (or myocardial infarction). Heart muscle disease (cardiomyopathy) can do the same. The cusps and chordae may deteriorate. This is called mitral valve prolapse. This usually occurs alone, but may be part of a rare condition called Marfan’s syndrome where there are also abnormalities of other parts of the body. Infection on an abnormal mitral valve leads to a disease called infective endocarditis, and can occur even if the valve abnormality is minor. This usually causes a worsening of any previously leaking valve. Treatment Involved for Mitral Valve Disease During Treatment for Mitral Valve Disease Regular check-ups are important to make sure that the valve defect and its effect on the heart's pumping does not become dangerous. Should breathlessness occur or get worse, seek advice from your doctor. Treatment may need to be started or increased. It is especially important to seek help if you develop rapid palpitation. This may cause a sudden increase in breathlessness even at rest. If germs get into the bloodstream there is a risk of getting infection on an abnormal mitral valve. This is called infective endocarditis and it can happen even if the valve defect is minor. Germs get into the blood through the gums after dental treatment or with other operations or investigations which use instruments passed inside the body. Prevention, by taking antibiotics, is better than cure. They are given, usually by mouth, an hour before dentistry or an operation. You should carry a card with all the details. Show it to any doctor or dentist treating you.

Liang, M.D. More on: our services Mitral Valve Disease By Bruce T. Liang, M.D. The valves of the heart work like flaps to keep blood flowing in a one-way direction. The mitral valve connects the left atrium to the left ventricle. Normally, it opens to let blood flow from the left atrium to the left ventricle and then closes when the left ventricle contracts, sending blood out of the left ventricle through the aorta to the rest of the body. When the mitral valve fails to close properly during the contraction of the ventricle, a condition known as mitral regurgitation occurs. In this condition, blood flows or leaks back into the left atrium causing pressure in the lungs that can result in congestion and the symptoms of shortness of breath and easy fatigue. Coronary artery disease can cause a form of mitral regurgitation, known as ischemic mitral regurgitation. This usually results from the stretching or displacement of the papillary muscle that holds the valve to the ventricle. Generally, coronary bypass surgery or angioplasty does not correct ischemic mitral regurgitation. Valve repair or replacement is needed. Surgeons and anesthesiologists caring for patients with ischemic regurgitation in the operating room should be aware that the severity of regurgitation may become deceptively modest during administration of anesthesia.
