| 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) |
