| mitral valve | <anatomy, cardiology> The heart valve that divides the left atrium and left ventricle. During left atrial contraction, the mitral valve opens to allow blood to flow into the left ventricle. Upon closure, the mitral valve prohibits the regurgitation of blood back into the left atrium. The mitral valve is the only heart valve that has only 2 valve cusps (all others have 3). (13 Nov 1997) |
|---|---|
| mitral valve insufficiency | Backflow of blood from the left ventricle into the left atrium, owing to imperfect functioning of the mitral valve. (12 Dec 1998) |
| mitral valve prolapse | <cardiology> A systolic click-murmur syndrome, floppy-valve syndrome and billowing mitral leaflet syndrome. A common, but highly variable (most individuals are asymptomatic), clinical syndrome that has been described in up to 7% of all females in the 14 to 30 age group. There is also an increased familial incidence suggesting an autosomal dominant form of inheritance. Treatment often includes the avoidance of stimulants (caffeine, nicotine, decongestants) and the use of a beta-blocker medication in select cases. Inheritance: autosomal dominant. Synonym:: Barlow's syndrome. (13 Nov 1997) |
| mitral valve prolapse syndrome | <syndrome> The clinical constellation of findings with or without symptoms due to prolapse of the mitral valve: a nonejection systolic click accentuated in the standing posture, sometimes multiple, sometimes with mitral regurgitation occurring relatively late in systole, and accompanied by echocardiographic evidence of the mitral valve prolapse, usually with thickened leaflets of the valve. Symptoms are non-specific and may include vague chest pains and dyspnea on exertion. Synonym: billowing mitral valve syndrome. (05 Mar 2000) |
| mitral valve stenosis | A rheumatic disease causing diffuse thickening of the mitral valve leaflets by fibrous tissue or calcific deposits. (harrisons' principles of internal medicine, 13th ed, p1052) (12 Dec 1998) |
| congenital absence of pulmonary valve | <radiology> BIG central pulmonary arteries, big RV (12 Dec 1998) |
| congenital valve | An abnormal lining fold obstructing a passage; e.g., of a mucous membrane in the urethra. (05 Mar 2000) |
| coronary valve | A delicate fold of endocardium at the opening of the coronary sinus into the right atrium. Synonym: valvula sinus coronarii, coronary valve, thebesian valve. (05 Mar 2000) |
| porcine valve | A prosthetic cardiac valve derived from the pig heart, which is preserved and sterilised with glutaraldehyde, and permanently sutured to a shape-retaining artificial strut; in appropriate sizes, it can replace any natural heart valve. Synonym: porcine valve. (05 Mar 2000) |
| posterior cusp of atrioventricular valve | The posterior leaflet of either the tricuspid or mitral valves. Synonym: cuspis posterior valvae atrioventricularis dextrae/sinistrae. (05 Mar 2000) |
| Hasner's valve | A fold of mucous membrane guarding the lower opening of the nasolacrimal duct. Synonym: plica lacrimalis, Bianchi's valve, Hasner's fold, Hasner's valve, Huschke's valve, Rosenmuller's valve. (05 Mar 2000) |
| heart valve | <anatomy> A term used to describe anyone of the main 4 valves of the heart: tricuspid, mitral, aortic or pulmonic valves. Mitral valve separates left atrium and left ventricle, pulmonic valve separates pulmonary vein and left atrium, tricuspid valve separates right atrium and right ventricle, aortic valve separates left ventricle and the aorta (27 Sep 1997) |
| heart valve prolapse | Displacement of the valves of the heart. (12 Dec 1998) |
| heart valve prosthesis | An artificial substitute for a heart valve. It may be mechanical or composed of tissue. (12 Dec 1998) |
| heart valve prosthesis implantation | Surgical insertion of synthetic material to repair injured or diseased heart valves. (12 Dec 1998) |
