Heart Valve Replacement Tissue valves are made with tissues from porcine (pig) heart valves or bovine (cow) cardiac tissue because they function like human heart valves. Once the tissue is removed from the animal, it is chemically treated to preserve the tissue and prevent immulogic reactions once it is placed in a patient.

Mitral Valve Prolapse  (MVP) Mitral valve prolapse (MVP) is a condition in which the heart’s mitral valve doesn’t work well. The flaps of the valve are “floppy” and may not close tightly. These flaps normally help seal or open the valve. Much of the time, MVP doesn’t cause any problems. Rarely, blood can leak the wrong way through the floppy valve.

Valve Disease 1 A weakening of the valve tissue caused by energy changes in the body. 2  This is called myxomatous degeneration. 3  It happens most often in elderly patients and commonly affects the mitral valve. 4  A buildup of calcium on the aortic or mitral valves, which causes the valves to thicken.very 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. Two types of problems can disrupt blood flow though the valves: regurgitation or stenosis.

- Tissue Valves. Tissue heart valves can come from a variety of sources: porcine (pig), bovine (cow) and homografts or allografts (human). The primary advantage of a tissue valve over a mechanical valve is that you do not need to be on lifelong blood-thinner medication.issue heart valves can come from a variety of sources: porcine (pig), bovine (cow) and homografts or allografts (human).

- Eventually, you may need to have your faulty heart valve repaired or replaced. Some types of congenital heart valve disease are so severe that the valve is repaired or replaced during infancy, childhood, or even before birth. Other types may not cause problems until middle-age or older, if at all.

Valvular and Vascular Repair and Regeneration Autologous biological heart valves. People with valvular heart disease may require surgery to repair or replace the damaged heart valve. While many mechanical and biological replacement options exist today, each has its drawbacks. Center for Regenerative Medicine researchers plan to develop biological heart valves using a patient's own cells.

Porcine Valves â What is A Porcine Heart Valve Replacement? Still, most tissue valves, including porcine valves, are not as durable as the mechanical valve replacements which are made substances including titanium, Teflon and steel. Obviously, this is one of the downsides of porcine valves as porcine valve leaflets tend to calcify and degenerate.This can lead to a collapsed pig valve in the human heart. However, some recent studies are beginning to challenge that adverse effect of pig valves.till, most tissue valves, including porcine valves, are not as durable as the mechanical valve replacements which are made substances including titanium, Teflon and steel.

Heart Disease: Heart Valve Disease What Causes Heart Valve Disease? Heart valve disease can develop before birth (congenital) or can be acquired sometime during one's lifetime. Sometimes, the cause of valve disease is unknown. Congenital valve disease. This form of valve disease most often affects the aortic or pulmonic valve.

- The heart is divided into four main areas, or chambers – two upper chambers (called the left and right atrium) and two lower chambers (called the left and right ventricle). There are four valves that control the flow of blood through your heart.here are two common problems that can develop in heart valves: When your valve is narrowed and does not completely open because of things like a build-up of calcium (mineral deposits), high cholesterol (a waxy fat), age, or genetics (such as a birth defect), this is called stenosis.

Bicuspid Aortic Disease A normal aortic valve (see below) has three leaflets (also known as flaps or cusps). These open and close to control the flow of blood into the aorta from the left ventricle of the heart as it beats. When the flaps come together as the valve closes, the shape is like a circle divided into thirds. The mitral valve may leak blood due to bicuspid leaflets. 2  One of the three layers of the wall of the aorta becomes thin and weak. 3  As a result, the aorta cannot stretch and contract properly when the heart beats and pumps blood into the aorta.

The Impact of Congenital Heart Defects When all chambers and valves work correctly, the blood is pumped through the heart, to the lungs for oxygen, back the heart and out to the body for delivery of oxygen. When valves, chambers, arteries and veins are malformed, this circulation pattern can be impaired. Congenital heart defects are malformations that are present at birth. They may or may not have a disruptive effect on a person's circulatory system. Learn how the healthy heart works.

- People who have certain heart conditions are at. increased risk for poor outcomes from endocarditis. Heart conditions that put people at higher risk for. poor outcomes from IE include: • artificial (prosthetic) heart valves or heart valves. repaired with artificial material. • a history of endocarditis. • some kinds of congenital heart defects. • abnormality of the heart valves after a heart. transplant. Infective (bacterial) endocarditis (IE) is an. infection of either the heart’s inner lining. (endocardium) or the heart valves.

- Valvular heart disease is characterized by damage to or a defect in one of the four heart valves: the mitral, aortic, tricuspid or pulmonary. The mitral and tricuspid valves control the flow of blood between the atria and the ventricles (the upper and lower chambers of the heart). High blood pressure and atherosclerosis may damage the aortic valve. 2  A heart attack may damage the muscles that control the heart valves. 3  Other disorders such as carcinoid tumors, rheumatoid arthritis, systemic lupus erythematosus, or syphilis may damage one or more heart valves.

- Heart valves are normally thin, smooth structures that open to allow blood to flow through the heart’s four chambers and then close tight to prevent back flow. If one of them does not function normally, it can cause the heart to work harder and create symptoms such as shortness of breath, dizziness, or chest pain.

Heart Valves Disease of the heart valves can be a serious condition because it directly affects the flow of blood through the heart. Valve stenosis prevents the valve from opening fully and this can obstruct or restrict the blood flow which strains the heart, forcing it to work harder in order to pump the blood past the narrowing.

- Many people have heart valve defects or disease but don't have symptoms. For some people, the condition mostly stays the same throughout their lives and doesn't cause any problems. For other people, heart valve disease slowly worsens until symptoms develop. If not treated, advanced heart valve disease can cause heart failure, stroke, blood clots, or death due to sudden cardiac arrest (SCA).

Heart Heart valve disease occurs if one or more of your heart valves don't work well. The heart has four valves: the tricuspid, pulmonary, mitral, and aortic valves. These valves have tissue flaps that open and close with each heartbeat. The flaps make sure blood flows in the right direction through your heart's four chambers and to the rest of your body.

- Some of the causes include rheumatic disease, endocarditis (infection of the valve), connective tissue diseases (weakening of the tissues that make up the support structures within the body), and congenital diseases. Although the aortic valve may rarely be repaired more often it requires replacement.

Heart Disease: Heart Valve Disease The narrowed opening may make the heart work very hard to pump blood through it. This can lead to heart failure and other symptoms (see below). All four valves can be stenotic (hardened, restricting blood flow); the conditions are called tricuspid stenosis, pulmonic stenosis, mitral stenosis or aortic stenosis.

Heart Valve Problems A heart valve problem is acquired if it occurs in a valve that was structurally normal at birth. Some causes of acquired heart valve problems include: Rheumatic fever, an inflammatory illness that may follow an untreated strep throat infection. Endocarditis, inflammation and infection of the heart valves.

Different Types of Heart Valve Problems Posted on Jun 10, 2013 | Comments 0. A heart valve disease is a kind of a heart condition which occurs when the valves of the heart do not work as they are expected to work. Heart valves are located at the exits of the four heart chambers and help in maintaining the one-way blood flow through the heart. The four valves ensure the fact that the blood always flows in the forward direction and not the backward direction.
