| tricuspid atresia | Absence of the orifice between the right atrium and ventricle, with the presence of an atrial defect through which all the systemic venous return reaches the left heart. As a result, there is left ventricular hypertrophy (hypertrophy, left ventricular) because the right ventricle is absent or not functional. (12 Dec 1998) |
|---|---|
| follicular atresia | <physiology> The degeneration and resorption of an ovarian follicle before it reaches maturity and ruptures. (12 Dec 1998) |
| laryngeal atresia | Congenital failure of the laryngeal opening to develop, resulting in partial or total obstruction at or just above or below the glottis. (05 Mar 2000) |
| aortic stenosis | Progressive narrowing of the aortic valve resulting in the obstructed passage of blood from the left ventricle into the aorta. Causes for aortic stenosis include rheumatic fever, congenital and idiopathic sclerosis. Chronic stenosis can lead to left ventricular enlargement and congestive heart failure. (27 Sep 1997) |
| aortic valve stenosis | Narrowing of the orifice of the aortic valve or of the supravalular or subvalvular regions. (12 Dec 1998) |
| 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) |
| calcific nodular aortic stenosis | Most common type of aortic stenosis, occurring usually in elderly men, in which the cusps contain calcified fibrous nodules on both surfaces; the causes include rheumatic fever, atherosclerosis, age-related degeneration, and congenitally bicuspid aortic valve. (05 Mar 2000) |
| valvular aortic stenosis | <radiology> Secondary to fusion of commisures between cusps types: bicuspid/unicuspid (95%): in 1-2% of population; M>F; commonly associated with coarctation, tricuspid (5%), dysplastic thickened aortic cusps in infants with crtical aortic stenosis: may stimulate neonatal sepsis, associated with L-R shunts (atrial septal defect, VSD), marked CMG (thickened wall of LV), pulmonary venous hypertension, congestive heart failure child/adult: LV configuration with normal heart size, postenotic dilatation, calcified valve (60% of patients greater than24 y.o.) see: aortic stenosis (12 Dec 1998) |
| 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) |
