In regards to the diagnosis of<unk>  the body requires oxygenated blood for survival.<unk>  is not threatening to a developing fetus however, because the mother's placenta provides the needed oxygen since the baby's lungs are not yet functional. Once the baby is born its lungs must now provide the oxygen needed for survival, but with<unk>  there is no opening on the<unk>  valve for blood to get to the lungs and become oxygenated. Due to this, the newborn baby is blue in color and<unk>  can usually be diagnosed within hours or minutes after birth. The diagnosis of<unk>  can be done via the following exams/methods: an echocardiogram, chest x-ray, EKG and an exam to measure the amount of in the body. Classification Ventricular septal defect via echocardiogram There are two types of<unk> . *<unk>  with Intact Ventricular Septum <unk> -IVS) is a rare congenital malformation.<unk> -IVS involves complete blockage of the<unk>  valve located on the right side of the heart. This blockage prevents the flow of blood to the lungs. Because of this lack of blood flowing through the right side of the heart, the structures on that side, such as the<unk>  valve and the tricuspid valve, are abnormally small. *<unk>  with Ventricular Septal Defect <unk> -VSD) is identified by underdevelopment of the right ventricle. The Ventricular Septal Defect (VSD) is a second opening in the ventricular wall, which provides a way out for blood in the right ventricle. When this second opening does not exist, very little blood goes to the right ventricle, which is what causes it to be underdeveloped in<unk> -IVS, this defect can be determined before birth.
