| 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) |
| spinal stenosis | An abnormal narrowing of the spinal canal that may be either congenital or acquired. Treatment is generally surgical to widen the spinal canal. Laminectomy may be the indicated surgical procedure to reduce pressure on the spinal cord. (27 Sep 1997) |
| stenosis | Narrowing or stricture of a duct or canal. Origin: Gr. Stenosis (18 Nov 1997) |
| subaortic stenosis | <cardiology> The congenital narrowing of the outflow tract of the left ventricle due to a ring of fibrous tissue or enlargement of the ventricular septum. (27 Sep 1997) |
| subvalvar stenosis | <cardiology> The congenital narrowing of the outflow tract of the left ventricle due to a ring of fibrous tissue or enlargement of the ventricular septum. (27 Sep 1997) |
| subvalvular aortic stenosis | <radiology> Types: anatomic/fixed subaortic stenosis: associated with cardiac defects in 50% (usually VSD), functional/dynamic subartic stenosis: asymetrical septal hypertrophy (ASH), idiopathic hypertrophic subaortic stenosis (IHSS), hypertrophic obstructive cardiomyopathy (HOCM) findings: asymmetrically thicker ventricular septum than free wall of the left ventricle (95%), normal/small left and right ventricular cavities (95%), systolic anterior motion of the mitral valve, lucent subaortic filling defect in systole, coarse systolic flutter of valve cusps, may see mitral regurgitation (secondary to abnormal position of anterolateral pappilary muscle) see: aortic stenosis (12 Dec 1998) |
| supravalvar aortic stenosis-infantile hypercalcaemia syndrome | <syndrome> Supravalvar aortic stenosis associated with elfin facies, mental retardation, and hypercalcaemia; usually sporadic; perhaps an irregular dominant trait. (05 Mar 2000) |
| supravalvar aortic stenosis syndrome | <syndrome> Supravalvar aortic stenosis (usually membranous) sometimes associated with pulmonary valvular or peripheral arterial stenosis but with normal facies and mentality; autosomal dominant inheritance. Compare: Williams syndrome. (05 Mar 2000) |
| supravalvar stenosis | Narrowing of the aorta above the aortic valve by a constricting ring or shelf, or by coarctation or hypoplasia of the ascending aorta. (05 Mar 2000) |
| supravalvular aortic stenosis | <radiology> Types: localised hourglass narrowing just above aortic sinuses, discrete fibrous membrane above sinuses of Valsalva, diffuse tubular hypoplasia of ascending aorta and branching arteries associated with: peripheral pulmonary stenosis, valvular and discrete subvalvular aortic stenosis, Marfan syndrome, Williams syndrome findings: dilatation and tortuosity of coronary arteries (may undergo early atherosclerotic degeneration secondary to high pressure), narrowing of the supravalvular area (normal root diameter: 20-37mm), normal movement of cusps (12 Dec 1998) |
| supravalvular stenosis | Stenosis distal to the aortic valve due usually to a congenital membrane. Patients usually have a kind of "elfin" facies and resemble each other more than they do members of their family. (05 Mar 2000) |
| Dittrich's stenosis | Narrowing of the outflow tract of the right ventricle below the pulmonic valve; may be due to a localised fibrous diaphragm just below the valve or, more commonly, to a long narrow fibromuscular channel. Synonym: Dittrich's stenosis. (05 Mar 2000) |
