Definitions related to aortic valve insufficiency:
-
(aortic regurgitation) An insufficiency of the aortic valve, leading to regurgitation (backward flow) of blood from the aorta into the left ventricle.Human Phenotype Ontology (HPO)The Human Phenotype Ontology Project, 2021
-
Backflow of blood from the aorta into the left ventricle, owing to imperfect functioning of the aortic semilunar valve.CRISP ThesaurusNational Institutes of Health, 2006
-
Dysfunction of the aortic valve characterized by incomplete valve closure.NCI ThesaurusU.S. National Cancer Institute, 2021
-
Pathological condition characterized by the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to regurgitation. It is caused by diseases of the AORTIC VALVE or its surrounding tissue (aortic root).NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
(aortic valve regurgitation) The backward flow of blood from the aorta into the left ventricle, owing to insufficiency of the aortic semilunar valve; it may be chronic or acute.NCI ThesaurusU.S. National Cancer Institute, 2021
-
(aortic valve insufficiency/ regurgitation) Incomplete closure or damage to a valve leaflet of the aortic valve, resulting in aortic valve backflow.U.S. FDA GlossaryU.S. Food & Drug Administration, 2021
-
Aortic regurgitation (AR) is incompetency of the aortic valve causing backflow from the aorta into the left ventricle during diastole. Causes include valvular degeneration and aortic root dilation (with or without a bicuspid valve), rheumatic fever, endocarditis, myxomatous degeneration, aortic root dissection, and connective tissue (eg,...Merck & Co., Inc., 2020
-
Aortic regurgitation (AR) is the diastolic flow of blood from the aorta into the left ventricle (LV). Regurgitation is due to incompetence of the aortic valve or any disturbance of the valvular apparatus (eg, leaflets, annulus of the aorta) resulting in the diastolic flow of blood into the left ventricular chamber.WebMD, 2019
-
Aortic valve regurgitation - or aortic regurgitation - is a condition that occurs when your heart's aortic valve doesn't close tightly. Aortic valve regurgitation allows some of the blood that was pumped out of your heart's main pumping chamber (left ventricle) to leak back into it.Mayo Foundation for Medical Education and Research
-
Aortic regurgitation (AR) is the diastolic leakage of blood from the aorta into the left ventricle. It occurs due to inadequate coaptation of valve leaflets resulting from either intrinsic valve disease or dilation of the aortic root. It can remain asymptomatic for decades before patients present with irreversible myocardial damage.Athenahealth, Inc., 2019
-
Aortic insufficiency, failure of the valve at the mouth of the aorta--the principal artery that distributes blood from the heart to the tissues of the body--to prevent backflow of blood from the aorta into the left lower chamber (ventricle) of the heart, from which it has been pumped. The defect...Encyclopedia Britannica, Inc., 2020
