| mitral stenosis | <cardiology> A congenital or acquired heart valve abnormality that describes the narrowing and ineffective opening of the mitral valve. (13 Nov 1997) |
|---|---|
| mitral tap | The palpable equivalent of the opening snap of the mitral valve. (05 Mar 2000) |
| 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) |
| mitral valvotomy | Deliberate incision or enlargement by inserting a finger in the mitral valve due to mitral stenosis. (05 Mar 2000) |
| ischemic mitral regurgitation | A regurgitation of the mitral valve caused by ischemic heart disease. (05 Mar 2000) |
| fish-mouth mitral stenosis | Extreme mitral stenosis. (05 Mar 2000) |
| abdominal ring | The opening in the transversalis fascia through which the ductus deferens (or round ligament in the female) and gonadal vessels enter the inguinal canal. Located midway between anterior superior iliac spine and pubic tubercle, it is bounded medially by the lateral umbilical ligament (inferior epigastric vessels) and inferiorly by the inguinal ligament. Indirect inguinal hernias exit the abdominal cavity via the deep inguinal ring Synonym: annulus inguinalis profundus, abdominal ring, annulus abdominalis, internal inguinal ring. (05 Mar 2000) |
| amnion ring | The ring formed by the attachment of the amnion to the umbilical cord at its point of emergence from the umbilicus. (05 Mar 2000) |
| annuloplasty ring | The dilated annulus is sutured, often to a prosthetic ring, thereby reducing it to its normal systolic size. (05 Mar 2000) |
| anterior limiting ring | The periphery of the cornea marking the termination of Descemet's membrane and the anterior border of the trabecular meshwork; an important landmark in gonioscopy. Synonym: Schwalbe's ring. (05 Mar 2000) |
| Balbani ring | An extremely large puff at a band of a polytene chromosome. (05 Mar 2000) |
