| valvular pneumothorax | A variety of spontaneous pneumothorax in which air enters the pleural cavity and is trapped during expiration; intrathoracic pressure builds to values higher than atmospheric pressure, compresses the lung, and may displace the mediastinum and its structures toward the opposite side, with consequent disadvantageous effects on blood flow. Synonym: pressure pneumothorax, valvular pneumothorax. (05 Mar 2000) |
|---|---|
| valvular prolapse | <syndrome> A syndrome, particularly of the atrioventricular valves, in which systole causes a sudden tensing of a scallop of a valve or an entire cusp producing the auscultatory click. Synonym: valvular prolapse. (05 Mar 2000) |
| valvular regurgitation | A leaky state of one or more of the cardiac valves, the valve not closing tightly and blood therefore regurgitating through it. Synonym: valvular incompetence, valvular insufficiency. (05 Mar 2000) |
| valvular sclerosis | Fibrosis, often with calcification of valves, considered to be an aging change and not due to primary valvular disease. (05 Mar 2000) |
| valvular thrombus | A parietal thrombus that projects into the lumen of the vessel. (05 Mar 2000) |
| prominence of venous valvular sinus | A slight eminence on the external wall of a vein correlating with the valvular sinus immediately proximal to the leaflets of the venous valve. Synonym: agger valvae venae. (05 Mar 2000) |
| aqueductal stenosis | <radiology> most common cause of congenital hydrocephalus (43%), aqueduct develops about the 6th week of gestation, M:F = 2:1, other congenital anomalies (16%): thumb deformities, prognosis: 11-30% mortality aetiology: infectious (50%): toxoplasmosis, CMV, syphillis, mumps, influenza, developmental: forking, narrowing, transverse septum (X-linked recessive), neoplastic (extremely rare): glioma, pinealoma, meningioma (12 Dec 1998) |
| buttonhole stenosis | Extreme narrowing, usually of the mitral valve. (05 Mar 2000) |
| carotid stenosis | The narrowing or stricture of a carotid artery that may lead to transient ischemic attacks (see cerebral ischemia, transient) and stroke (see cerebrovascular disorders). (12 Dec 1998) |
| renal artery stenosis | <cardiology, nephrology> A narrowing of the renal artery or one of its main branches accounts for 2 to 5% of cases of hypertension. (27 Sep 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) |
| 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 pyloric stenosis | <radiology> Not seen until 3 weeks, projectile vomiting, palpable olive in RUQ/epigastrium (12 Dec 1998) |
| muscular subaortic stenosis | <cardiology> A congenital heart disease that results in abnormal thickening of the ventricular septum and left ventricular wall. Enlargement of the ventricular septum can result in ventricular outflow obstruction (subaortic stenosis) and eventual cardiomyopathy. (27 Sep 1997) |
| coronary ostial stenosis | Narrowing of the mouths of the coronary arteries as a result of syphilitic aortitis or atherosclerosis. (05 Mar 2000) |
