| rheumatic valvulitis | Valvulitis characterised in the acute stage by small fibrin vegetations along the lines of closure and by Aschoff bodies in the cusps; in the chronic stage, it is characterised by scarring, commissural adhesion, and stenosis and/or regurgitation. (05 Mar 2000) |
| 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) |
| billowing mitral valve 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) |
| parachute mitral valve | Congenital deformity of the mitral valve characterised by the presence of a single papillary muscle from which the chordae of both valve leaflets divide; thus the resemblance to a parachute; the condition often produces a stenosis as the combined result of the tugging action of the chordae on and the subsequent narrowing between the leaflets. Synonym: parachute deformity. (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 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 prolapse | Drooping down or abnormal bulging of the mitral valve cusps during the contraction of the heart. (12 Dec 1998) |
