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)
The aortic, mitral, pulmonary, and tricuspid valves are four valves that open and close to direct blood flow through the heart. (fetanzena.com)
Many factors can cause your heart valves to become narrowed (stenosis), leak (regurgitation or insufficiency), or close improperly. (fetanzena.com)
Valves of the heart in motion, the front wall of the heart is removed in this image. (wikipedia.org)
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 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)
Fast Five Quiz: Heart Valve Disease - Medscape - Apr 22, 2020. (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)
Although valvular lesions were observed on both sides of the heart, a left-sided valve was affected in all cases. (cdc.gov)

After aortic cross-clamp was applied, antegrade cold blood cardioplegia was administered, and a left atrial incision was performed. (ctsnet.org)
Mitral regurgitation leads to left atrial enlargement and may cause subsequent atrial fibrillation. (health.am)
TEE provides better-quality images than TTE and is more accurate in assessing the anatomical features of the valve and the presence of left atrial appendage thrombus. (medscape.com)

Such replacement valves often include a tissue-based valve body that is connected to an expandable frame that is then delivered to the native valve's annulus. (justia.com)
Enlargement of the mitral annulus and left ventricular cavity produce mitral valvular insufficiency. (justia.com)
Annuloplasty rings may be used in conjunction with any repair procedures where contracting or stabilizing the valve annulus might be desirable. (justia.com)
