| PIAVA | polydactyly-imperforate anus-vertebral anomalies [syndrome] |

| BRBPR | bright red blood per rectum |
| IPHR | inverted polypoid hamartoma of the rectum |
| 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) |
| double aortic stenosis | Subaortic stenosis associated with stenosis of the valve itself, both lesions being congenital. (05 Mar 2000) |
| idiopathic hypertrophic 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) |
| infundibular 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) |
| oesophageal stenosis | Stricture of the oesophagus. (12 Dec 1998) |
| tricuspid stenosis | Pathologic narrowing of the orifice of the tricuspid valve. (05 Mar 2000) |
| tricuspid valve stenosis | The pathologic narrowing of the orifice of the tricuspid valve. (12 Dec 1998) |
| fish-mouth mitral stenosis | Extreme mitral stenosis. (05 Mar 2000) |
| laryngeal stenosis | Narrowing or stricture of any or all areas of the larynx; may be congenital or acquired. (05 Mar 2000) |
| abstracting and indexing | Shortening or summarizing of documents; assigning of descriptors for referencing documents. (12 Dec 1998) |
