| complete endocardial cushion defect | <radiology> Arteriovenous canal components: low atrial septal defect (ostium primum), high VSD, cleft anterior leaflet of mitral valve, cleft septal leaflet of tricuspid valve, one AV valve common to RV and LV with 5-6 leaflets findings: 4-chamber enlargement (R greater than L), mitral insufficiency, associated with congestive heart failure and Eisenmenger syndrome, gooseneck deformity on angiogram (elongation and narrowing of the LV outflow tract during diastole) see also: endocardial cushion defect, partial endocardial cushion defect (12 Dec 1998) |
| congenital defect | A birth defect. (12 Dec 1998) |
| congenital ectodermal defect | Incomplete development of the epidermis and skin appendages; the skin is smooth and hairless, the facies abnormal, and the teeth and nails may be affected; sweating may be deficient. Synonym: congenital ectodermal dysplasia. (05 Mar 2000) |

| neural tube defect | <neurology, paediatrics> Abnormal development during embryonic life of the neural tube producing congenital malformations of the nervous system due to closure failure of the neural tube. The structure gives rise to the central nervous system (the brain and spinal cord), and failure to close results in anencephaly (absence of the cranial vault and absence of most or all of the cerebral hemispheres of the brain) and spina bifida or meningomyelocele (open spina with exposure and protusion of the spinal cord). The risk of neuroal tube defects can be decreased by the mother taking folic acid during pregnancy. (04 Jul 1999) |
| defect | 1. Want or absence of something necessary for completeness or perfection; deficiency; opposed to superfluity. "Errors have been corrected, and defects supplied." (Davies) 2. Failing; fault; imperfection, whether physical or moral; blemish; as, a defect in the ear or eye; a defect in timber or iron; a defect of memory or judgment. "Trust not yourself; but, your defects to know, Make use of every friend any every foe." (Pope) "Among boys little tenderness is shown to personal defects." (Macaulay) Synonym: Deficiency, imperfection, blemish. See Fault. Origin: L. Defectus, fr. Deficere, defectum, to desert, fail, be wanting; de- + facere = to make, do. See Fact, Feat, and cf. Deficit. Source: Websters Dictionary (01 Mar 1998) |
| defect, enzyme | An abnormality in the protein (enzyme) important in catalyzing a normal biochemical reaction in the body. Disorders result from a deficiency (or functional abnormality) of an enzyme. Archibald Garrod in 1902 was the first to attribute a disease to an enzyme defect: an inborn error of metabolism. Today, newborns are routinely screened for certain enzyme defects such as phenylketonuria (PKU) and galactosaemia, an error in the handling (metabolism) of the sugar galactose. (12 Dec 1998) |

| oesophageal filling defect | <radiology> Tumour, carcinoma (oesophagus, stomach extending proximally), leiomyoma / leiomyosarcoma, polyp: fibrovascular, inflammatory, adenomatous, papilloma, carcinosarcoma, lymphoma, metastasis, oesophageal varix, extrinsic lesion (vascular impression, adenopathy, cyst), foreign body (12 Dec 1998) |
| osteoporotic marrow defect | Focal osteoporotic bone marrow defect of the jaw; a focal radiolucent defect composed of normal marrow. (05 Mar 2000) |
| Eisenmenger's defect | The combination of ventricular septal defect with pulmonary hypertension and consequent right-to-left shunt through the defect, with or without an associated overriding aorta. Synonym: Eisenmenger's defect, Eisenmenger's disease, Eisenmenger's tetralogy. (05 Mar 2000) |
| endocardial cushion defect | <radiology> Persistence of primitive atrioventricular canal and anomalies of AV valves associated with: Down syndrome: in 25% of Trisomy 21 an ECD is present; in 45% of ECD Trisomy 21 is present, asplenia/polysplenia types: complete (AV canal), partial findings: gooseneck deformity on angiogram, increased pulmonary vascularity, enlarged pulmonary artery, enlarged RV, LV, RA; normal LA (secondary to atrial septal defect) (12 Dec 1998) |
