| prolapse of umbilical cord | Presentation of part of the umbilical cord ahead of the foetus; it may cause foetal death due to compression of the cord between the presenting part of the foetus and the maternal pelvis. (05 Mar 2000) |
|---|---|
| uterine prolapse | The abnormal downward displacement of the uterus from its normal anatomic position within the pelvis. Higher grade prolapse can result in protrusion of the uterus from the vaginal canal. (27 Sep 1997) |
| anomalous mitral arcade | Short chordae tendineae extending from both papillary muscles to the central portion of the anterior leaflet of the mitral valve and resulting in stenosis or incompetence of the valve. (05 Mar 2000) |
| mitral | Pertaining to a miter; resembling a miter; as, the mitral valve between the left auricle and left ventricle of the heart. Origin: Cf. F. Mitral. See Miter. Source: Websters Dictionary (01 Mar 1998) |
| mitral area | The region of the chest over the apex of the heart, where the sounds, normal or pathologic, produced at the mitral valves are usually heard most distinctly. (05 Mar 2000) |
| mitral cells | Large nerve cell's in the olfactory lobe of the brain whose dendrites synapse (in glomeruli) with axons of the olfactory receptor cell's of the nasal mucous membrane, and whose axons pass centrally in the olfactory tract to the olfactory cortex. (05 Mar 2000) |
| mitral commissurotomy | Opening the narrowed mitral orifice for the relief of mitral stenosis. (05 Mar 2000) |
| mitral facies | The pink, slightly cyanosed cheeks of patients with mitral valve disease. (05 Mar 2000) |
| mitral gradient | The diastolic pressure difference between the left atrium and left ventricle. (05 Mar 2000) |
| mitral incompetence | <cardiology> The back flow of blood from the left ventricle to the left atrium through a defective mitral bicuspid valve. The most common cause for mitral regurgitation is rheumatic fever. Other causes include: myocardial infarction, massive calcification of the mitral annulus (in the elderly), lupus, rheumatoid arthritis, infectious endocarditis and ankylosing spondylitis. (13 Nov 1997) |
| mitral insufficiency | Malfunction of the mitral valve. Mitral insufficiency allows the backflow of blood (regurgitation) from the left ventricle into the left atrium. (12 Dec 1998) |
| mitral murmur | A murmur produced at the mitral valve, either obstructive or regurgitant. (05 Mar 2000) |
| mitral orifice | An atrioventricular opening which leads from the left atrium into the left ventricle of the heart. Synonym: ostium atrioventriculare sinistrum, ostium arteriosum. (05 Mar 2000) |
| mitral regurgitation | <cardiology> The back flow of blood from the left ventricle to the left atrium through a defective mitral bicuspid valve. The most common cause for mitral regurgitation is rheumatic fever. Other causes include: myocardial infarction, massive calcification of the mitral annulus (in the elderly), lupus, rheumatoid arthritis, infectious endocarditis and ankylosing spondylitis. (13 Nov 1997) |
| mitral stenosis | <cardiology> A congenital or acquired heart valve abnormality that describes the narrowing and ineffective opening of the mitral valve. (13 Nov 1997) |
