Subclass of:
Heart valve disease
Also called:
Tricuspid Insufficiency; Tricuspid Regurgitation; Tricuspid Incompetence
Definitions related to tricuspid valve insufficiency:
-
(tricuspid regurgitation) Failure of the tricuspid valve to close sufficiently upon contraction of the right ventricle, causing blood to regurgitate (flow backward) into the right atrium.Human Phenotype Ontology (HPO)The Human Phenotype Ontology Project, 2021
-
Backflow of blood from the RIGHT VENTRICLE into the RIGHT ATRIUM due to imperfect closure of the TRICUSPID VALVE.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021

Dysfunction of the pulmonary valve characterized by incomplete valve closure.NCI ThesaurusU.S. National Cancer Institute, 2021
-
(tricuspid valve regurgitation) The backflow of blood from the right ventricle into the right atrium, owning to imperfect functioning/insufficiency of the tricuspid valve.NCI ThesaurusU.S. National Cancer Institute, 2021
-
(tricuspid valve insufficiency/ regurgitation) Incomplete closure or damage to a valve leaflet of the tricuspid valve, resulting in tricuspid valve backflow.U.S. FDA GlossaryU.S. Food & Drug Administration, 2021
-
Tricuspid regurgitation (TR) is insufficiency of the tricuspid valve causing blood flow from the right ventricle to the right atrium during systole. The most common cause is dilation of the right ventricle. Symptoms and signs are usually absent, but severe TR can cause neck pulsations, a holosystolic murmur, and right ventricular�induced...Merck & Co., Inc., 2020
-
Tricuspid regurgitation may result from structural alterations of any or all of the components of the tricuspid valve apparatus (see Anatomy). The lesion may be classified as primary when it is caused by an intrinsic abnormality of the valve apparatus or as secondary when it is caused by right ventricular (RV) dilatation.WebMD, 2019
-
Tricuspid valve regurgitation is a condition in which the valve between the two right heart chambers (right ventricle and right atrium) doesn't close properly. The malfunctioning valve allows blood to flow back into your heart's upper right chamber (right atrium).Mayo Foundation for Medical Education and Research
-
Tricuspid regurgitation (TR) occurs when blood flows backward through the tricuspid valve. In the vast majority of patients, this occurs during systole, but severely elevated right ventricular filling pressure can be associated with diastolic TR. TR can be primary (abnormal valve morphology) or secondary (normal valve morphology). Some...Athenahealth, Inc., 2019
