| PVOD | pulmonary vascular obstructive disease; pulmonary veno-occlusive disease |
| UPI | Utero-Placental Insufficiency |
| acc | insuff accommodation insufficiency |
| AMVI | acute mesenteric vascular insufficiency |
| tilting disc valve prosthesis | A low profile artificial heart valve with excellent flow characteristics. (05 Mar 2000) |
|---|---|
| tissue 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) |
| tricuspid valve | <anatomy> This heart valve, named for its three cusps (leaflets), divides the right atrium and the right ventricle. When the right atrium contracts blood flows through the tricuspid valve into the right ventricle. On closure, the tricuspid prohibits the backflow of blood into the right atrium. (19 Jan 1998) |
| tricuspid valve prolapse | Abnormal protrusion of one or more of the leaflets of the tricuspid valve into the right atrium during systole. (12 Dec 1998) |
| tricuspid valve stenosis | The pathologic narrowing of the orifice of the tricuspid valve. (12 Dec 1998) |
| Tulpius' valve | The bilabial prominence of the terminal ileum into the large intestine at the caecocolic junction as seen in cadavers; in the living individual it appears as a truncated cone with a star-shaped orifice. Synonym: valva ileocaecalis, Bauhin's valve, ileocaecal eminence, ileocolic valve, Tulp's valve, Tulpius' valve, valve of Varolius. (05 Mar 2000) |
| eustachian valve | An endocardial fold extending from the anterior inferior margin of the inferior vena cava to the anterior part of the limbus fossa ovalis. Synonym: valvula venae cavae inferioris, caval valve, eustachian valve, sylvian valve. (05 Mar 2000) |
| Krause's valve | A small fold in the interior of the lacrimal sac at its junction with the lacrimal duct. Synonym: Krause's valve. (05 Mar 2000) |
| floppy valve syndrome | <syndrome> Retrograde slippage of degenerating mitral or tricuspid valve leaflets into the valve's orifice beyond the point of closure during systole of the left ventricle; a feature of Barlow's syndrome. (05 Mar 2000) |
| frenulum of ileocaecal valve | A fold, more evident in cadavers, running from the junction of the two commissures of the ileocaecal valve on either side along the inner wall of the caecocolic junction. Synonym: frenulum valvae ileocaecalis, frenulum of Morgagni, Morgagni's frenum, Morgagni's retinaculum. (05 Mar 2000) |
| left atrioventricular 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) |
| lunula of semilunar valve | The free border of a semilunar valve at each side of the nodulus valvulae semilunaris. Synonym: lunula valvulae semilunaris. (05 Mar 2000) |
| acute pulmonary alveolitis | Acute inflammation involving exudate into the pulmonary alveoli and impaired gas exchange; may result in necrosis with haemorrhage into the lungs; occurs in Goodpasture's syndrome, in association with a glomerulonephritis. (05 Mar 2000) |
| acute pulmonary eosinophilia | <chest medicine> A self-limiting inflammation in the lungs where there is associated infiltration of eosinophils into lung tissue. Chest X-ray reveals pulmonary infiltrates and full blood count shows increased numbers of eosinophils. The cause is unknown and the disease often resolves without treatment. Some forms may be treated with oral corticosteroids. Complications include restrictive cardiomyopathy due to fibrosis of the lining of the heart. (27 Sep 1997) |
| adenomatosis, pulmonary | A neoplastic disease in which the alveoli and distal bronchi are filled with mucus and mucus-secreting columnar epithelial cells. It is characterised by abundant, extremely tenacious sputum, chills, fever, cough, dyspnea, and pleuritic pain. (12 Dec 1998) |
