Ebstein's anomaly
Ebstein's anomaly [eb´shtīnz]
Alder's anomaly an autosomal dominant condition in which leukocytes of the myelocytic series, and sometimes all leukocytes, contain coarse azurophilic granules.
Chédiak-Higashi anomaly see under syndrome.
congenital anomaly a developmental anomaly present at birth.
developmental anomaly
1. a structural abnormality of any type.
2. a defect resulting from imperfect embryonic development.
Ebstein's anomaly a malformation of the tricuspid valve, usually associated with an atrial septal defect. 
)
Ebstein's anomaly, showing displacement of the septal and posterior leaflets of the tricuspid valve into the right ventricle and accompanied by a patent foramen ovale.
May-Hegglin anomaly an autosomal dominant disorder of blood cell morphology, characterized by RNA-containing cytoplasmic inclusions (similar to Döhle bodies) in granulocytes, by large, poorly granulated platelets, and by thrombocytopenia.
Pelger's nuclear anomaly Pelger-Huët nuclear a. (1).
Pelger-Huët nuclear anomaly
1. a hereditary or acquired defect in which the nuclei of neutrophils and eosinophils appear rodlike, spherical, or dumbbell-shaped; the nuclear structure is coarse and lumpy.
2. an acquired condition with similar features, occurring in certain anemias and leukemias.
Eb·stein's anomaly ( b st nz, pshtnz)n. Congenital downward displacement of the tricuspid valve into the right ventricle. Also called Ebstein's disease. |
Ebstein's anomaly
Etymology: Wilhelm Ebstein, German physician, 1836-1912; Gk, anomalia, irregularity
a congenital heart defect in which the tricuspid valve is displaced downward into the right ventricle. The abnormality is often associated with right-to-left atrial shunting and Wolff-Parkinson-White syndrome.
Ebstein's anomaly [eb´shtīnz]
a malformation of the tricuspid valve, the septal and posterior leaflets being adherent to the wall of the right ventricle to a varying degree, producing tricuspid deficiency, and the anterior leaflet being normally attached to the annulus fibrosus; usually associated with an atrial septal defect.
Ebstein's anomaly with tricuspid valve significantly displaced downward in the right ventricle; leakage occurs through the tricuspid valve back to the right atrium, and unoxygenated blood is shunted across the atrial-septal defect into the left atrium. From Betz et al., 1994.
Ebstein's anomaly
a malformation of the tricuspid valve, usually associated with an atrial septal defect, characterized by a downward displacement of the base of the valves.
