endocardial cushion defect

per·sis·tent a·tri·o·ven·tric·u·lar ca·nal

a condition that is caused when the atrial and ventricular septa fail to meet, as in normal development, resulting in a low atrial and a high ventricular septal defect or a common atrioventricular canal.

endocardial cushion defect

[en′dōkär′dē·əl]
any cardiac defect resulting from the failure of the endocardial cushions in the embryonic heart to fuse and form the atrial septum. It is common in Down syndrome. See also atrial septal defect, congenital cardiac anomaly.

Complex CHD may be present in up to 18% of patients which include mitral valve prolapse, hypoplastic left heart syndrome, endocardial cushion defect, coarctation of aorta, patent ductus arteriosus, pulmonary hypertension, Tetrology of Fallot, (5) double outlet right ventricle, (6) truncus arteriosus, and total anomalous pulmonary venous return.
More complex cardiac lesions such as Tetrology of Fallot, endocardial cushion defects, double outlet right ventricle, and total anomalous pulmonary venous return are observed uncommonly.

In an exploratory analysis, we considered seven clinical diagnostic groupings of CHDs: a) conotruncal defects (tetralogy of Fallot and transposition of great vessels); b) endocardial cushion and mitrovalve defects (EMD; endocardial cushion defect and hypoplastic left heart syndrome); c) pulmonary artery and valve defects (PAV; pulmonary valve atresia and stenosis and pulmonary artery anomalies); d) tricuspid valve defects (TVD; tricuspid valve atresia and stenosis and Ebstein's anomaly); e) aortic artery and valve defects (aortic valve stenosis and coarctation of aorta); f) ventricular septal defects (VSD); and g) patent ductus arteriosis in births > 2,500 g (Gilboa et al.
