Definitions related to tricuspid atresia:
-
Absence of the orifice between the RIGHT ATRIUM and RIGHT VENTRICLE, with the presence of an atrial defect through which all the systemic venous return reaches the left heart. As a result, there is left ventricular hypertrophy (HYPERTROPHY, LEFT VENTRICULAR) because the right ventricle is absent or not functional.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
Failure to develop of the tricuspid valve and thus lack of the normal connection between the right atrium and the right ventricle.Human Phenotype Ontology (HPO)The Human Phenotype Ontology Project, 2021
-
Tricuspid atresia is (TA) a rare congenital heart malformation characterized by the congenital agenesis of tricuspid valve leading to severe hypoplasia of right ventricle (functionally univentricular). TA is associated with normally related or transposed great vessels (TGV, see this term), an obligatory interatrial connection that is crucial for survival (patent foramen ovale or atrial septal defect, osteum secondum type), ventricular septal defect (in 90% cases), pulmonary outflow obstruction - pulmonary atresia, stenosis or hypoplasia (usually in TA with normally related vessels but also in TGV), aortic coarctation and/or aortic arch interruption (usually in TA with TGV)(see these terms).OrphaNetINSERM, 2021
-
(tricuspid valve atresia) A congenital heart defect characterized by the complete lack of formation of the tricuspid valve. Cyanosis is the predominant clinical symptom.NCI ThesaurusU.S. National Cancer Institute, 2021
-
Tricuspid atresia is absence of the tricuspid valve accompanied by a hypoplastic right ventricle. Associated anomalies are common and include atrial septal defect, ventricular septal defect, patent ductus arteriosus, pulmonic valve stenosis, and transposition of the great arteries. Presenting signs include cyanosis or signs of heart...Merck & Co., Inc., 2020

Tricuspid atresia is the third most common form of cyanotic congenital heart disease, with a prevalence of 0.3-3.WebMD, 2019
-
Tricuspid atresia is a heart defect present at birth (congenital) in which a valve (tricuspid valve) between two of the heart's chambers isn't formed. Instead, there's solid tissue between the chambers, which restricts blood flow and causes the right lower heart chamber (ventricle) to be underdeveloped.Mayo Foundation for Medical Education and Research
