| 설명 | 관 혹은 통로에 있는 막과 같은 주름. 내용물의 역류를 막는다. 1.심장판막: 우심방과 우심실사이의 삼첨판, 좌심방과 좌심실사이의 승모판, 우심실과 폐동맥사이의 폐동맥반월판, 좌심실과 대동맥사이의 대동맥반월판이 있다. 2.정맥판막: 정맥에서 발견되는 내막의 작은 첨 혹은 주름. 탄력성이 적어 역류되기 쉬운 정맥혈의 흐름을 역류없이 정상적인 방향으로 지속되도록 해준다. 3.인공판막: 심장판막부족이나 심장판막협착이 있어 더이상 자신의 판막으로는 생존이 불가능할 때 대신 이식하게 되는 인공판막을 말한다. 크게 동물의 조직을 이용한 것과 그렇지 않은 것으로 양분할 수 있다. 동물의 조직을 이용한 것은 주로 돼지나 소의 판막 또는 심외막 등을 이용하며, 그렇지 않은 것은 특수한 금속을 이용하여 만든다. |

| 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) |
|---|---|
| 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) |
| 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) |
| pulmonary stenosis | <cardiology> A congenital or acquired heart valve defect. The abnormal narrowing and ineffective opening of the pulmonic valve. Symptoms include cyanosis and difficulty breathing. Treatment is surgical in most cases of significant valvular stenosis. (27 Sep 1997) |
| pulmonary subvalvular stenosis | Stenosis of the conus arteriosus (infundibulum) with or without involvement of the pulmonary valve. It is usually associated with a defect in the interventricular septum. (12 Dec 1998) |
| pyloric stenosis | <gastroenterology, paediatrics> A congenital disorder in which the pylorus is thickened causing obstruction of the gastric outlet (to the duodenum). More common in males. Symptoms of projectile vomiting begin several weeks after birth. Incidence: approximately 1 in 4,000 live births. (27 Sep 1997) |
| hypertrophic pyloric stenosis | <radiology> Not seen until 3 weeks, projectile vomiting, palpable olive in RUQ/epigastrium (12 Dec 1998) |
