An<unk><unk>  defect  usually occurs due to the failure in fusion of the septum<unk>  with the endocardial cushion. This defect is commonly associated with other cardiac anomalies in the septum such as ventricular<unk>  defect, mitral valve cleft, pulmonary stenosis, subaortic stenosis, left superior vena cava, coarctation and  atrioventricular<unk>  defect. The abnormalities of the atrioventricular valves include the cleft mitral valve, and the single atrioventricular valve (a single large, deformed valve that flows into both the right ventricle and the left ventricle). It is often associated with Down's syndrome.
