Definitions related to mitral valve insufficiency:
-
(mitral regurgitation) An abnormality of the mitral valve characterized by insufficiency or incompetence of the mitral valve resulting in retrograde leaking of blood through the mitral valve upon ventricular contraction.Human Phenotype Ontology (HPO)The Human Phenotype Ontology Project, 2021
-
Backflow of blood from the LEFT VENTRICLE into the LEFT ATRIUM due to imperfect closure of the MITRAL VALVE. This can lead to mitral valve regurgitation.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
Dysfunction of the mitral valve characterized by incomplete valve closure.NCI ThesaurusU.S. National Cancer Institute, 2021
-
(mitral valve regurgitation) The backward flow of blood from the left ventricle into the left atrium, owing to insufficiency of the mitral valve; it may be acute or chronic, usually due to mitral valve prolapse, rheumatic heart disease or a complication of cardiac dilatation.NCI ThesaurusU.S. National Cancer Institute, 2021
-
(mitral valve insufficiency/ regurgitation) Incomplete closure or damage to a valve leaflet of the mitral valve, resulting in mitral valve backflow.U.S. FDA GlossaryU.S. Food & Drug Administration, 2021
-
Mitral regurgitation (MR) is incompetency of the mitral valve causing flow from the left ventricle (LV) into the left atrium during ventricular systole. MR can be primary (common causes are mitral valve prolapse and rheumatic fever) or secondary to LV dilation or infarction. Complications include progressive heart failure, arrhythmias,...Merck & Co., Inc., 2020
-
Mitral regurgitation (MR) is defined as an abnormal reversal of blood flow from the left ventricle to the left atrium. It is caused by disruption in any part of the mitral valve apparatus, which comprises the mitral annulus, the leaflets (a large anterior [aortic] leaflet and a small posterior [mural] leaflet), the chordae tendineae, and...WebMD, 2019
-
Mitral valve regurgitation - also called mitral regurgitation, mitral insufficiency or mitral incompetence - is a condition in which your heart's mitral valve doesn't close tightly, allowing blood to flow backward in your heart. If the mitral valve regurgitation is significant, blood can't move through your heart or to the rest of your...Mayo Foundation for Medical Education and Research
-
The mitral valve apparatus consists of anterior and posterior leaflets, chordae tendineae, anterolateral and posteromedial papillary muscles, and mitral annulus. Any aberrations of the mitral valve apparatus, due to mechanical, traumatic, infectious, degenerative, congenital, or metabolic causes, may lead to mitral regurgitation (MR).Athenahealth, Inc., 2019
-
Mitral insufficiency, inability of the mitral valve to prevent the flow of blood back from the left ventricle, or lower chamber of the heart, into the left atrium, or upper chamber. Normally, the valve permits blood to flow from the atrium to the ventricle but prevents its return. Most often, the i...Encyclopedia Britannica, Inc., 2020
