When the mitral valve doesnt work as it should, however, your heart might not pump enough of the oxygen-rich blood to your body. (healthyheartworld.com)
Mitral valve regurgitation, the most common heart-valve disorder, is a leaky valve that allows blood to flow backward into the left atrium. (healthyheartworld.com)
At Hartford HealthCares Heart & Vascular Institute, our goal is to repair - whenever possible - your own living valve. (healthyheartworld.com)
Your heart has four valves. (wikidoc.org)
Normally, these valves open to let blood flow through or out of your heart, and then shut to keep it from flowing backward. (wikidoc.org)
Valve problems can be present at birth or caused by infections, heart attacks, or heart disease or damage. (wikidoc.org)
Heart valves play key roles in this one-way blood flow, opening and closing with each heartbeat. (wikidoc.org)
Because of the narrowed valve, your heart must work harder to move blood through your body. (wikidoc.org)
Also, valve disease may lead to heart muscle disease (cardiomyopathy), an irregular heartbeat (arrhythmia), and blood clots. (wikidoc.org)
Use of the anti-obesity medicines fen-phen and Redux, which were removed from the market after being linked to heart valve disease. (wikidoc.org)
Heart valve repair surgery is performed whenever it is possible to save the patient's own valve. (beaumont.org)
This machine pumps blood to the rest of the body while the heart is stopped and the valve is being repaired. (beaumont.org)
During the heart valve repair itself, the surgeon reconstructs the patient's existing valve so that it opens and closes properly and functions like a healthy valve. (beaumont.org)
The surgeon and the patient will discuss the various options for heart valve replacements and they will together decide which type is best for the patient. (beaumont.org)
Once the heart valve replacement surgery is performed, the replacement valve will function like a healthy valve. (beaumont.org)
Many factors can cause your heart valves to become narrowed (stenosis), leak (regurgitation or insufficiency), or close improperly. (fetanzena.com)

Sound of the heart valves closing in a healthy 16 year old girl. (wikipedia.org)
A heart valve is a one-way valve that allows blood to flow in one direction through the chambers of the heart . (wikipedia.org)
Four valves are usually present in a mammalian heart and together they determine the pathway of blood flow through the heart. (wikipedia.org)
A heart valve opens or closes according to differential blood pressure on each side. (wikipedia.org)
The four valves in the mammalian heart are two atrioventricular valves separating the upper atria from the lower ventricles - the mitral valve in the left heart, and the tricuspid valve in the right heart. (wikipedia.org)
The heart also has a coronary sinus valve and an inferior vena cava valve , not discussed here. (wikipedia.org)
The heart valves and the chambers are lined with endocardium . (wikipedia.org)
Heart valves separate the atria from the ventricles , or the ventricles from a blood vessel . (wikipedia.org)
3D - loop of a heart viewed from the apex, with the apical part of the ventricles removed and the mitral valve clearly visible. (wikipedia.org)
The causes of valvular heart disease are varied and differ for each type of valve disorder. (doctorlib.info)
Pathophysiology of valvular heart disease varies according to the valve and the disorder. (doctorlib.info)
The heart sounds transmitted are due to closing of heart valves, and abnormal heart sounds, called murmurs, usually represent valve incompetency or abnormalities. (medscape.com)
Blood flows through the heart in only one direction enforced by a valvular system that regulates opening and closure of valves based on pressure gradients (see image below). (medscape.com)
The pulmonary circuit is on the right side of the heart and serves the function of gas exchange. (medscape.com)
Although valvular lesions were observed on both sides of the heart, a left-sided valve was affected in all cases. (cdc.gov)

This video presents the case of a minimally invasive mitral valve (MV) and anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) repair in a twenty-one-month-old female patient. (ctsnet.org)
The left coronary artery ostium was resected with the wide, 10 x 20 mm area of the pulmonary artery wall, which was used to elongate the coronary vessel. (ctsnet.org)
Surgeons then performed tubular elongation of the left coronary artery at the expense of the pulmonary artery wall. (ctsnet.org)

Replacement valves are being designed to be delivered through minimally invasive procedures and even percutaneous procedures. (justia.com)
