In<unk><unk>  defect, a persistent opening in the upper interventricular septum resulting from failure of fusion with the aortic septum allows blood to flow from the high pressure left ventricle into the low pressure chamber or right ventricle.  Disruption of the<unk> ion process, from inherited perturbations during embryological development or acquired cardiac injury, may result in<unk><unk>  defects (VSDs).
