What heart defect that occurs approximately once in every 500 births. Babies born with this defect have?

The heart defect that occurs approximately once in every 500 births is called ventricular septal defect (VSD). Babies born with VSD have a hole in the wall (septum) that separates the heart's lower chambers (ventricles), which can lead to increased blood flow to the lungs and overworking of the heart. This condition can result in symptoms such as difficulty breathing, poor weight gain, and fatigue. Many small VSDs may close on their own, while larger defects may require medical intervention or surgery.
