Spina Bifida: Spina bifida is a birth defect characterized by a split of the spinal column, sometimes causing serious neurological problems, such as spina bifida cystica (myelomeningocele). The most common form, spina bifida occulta, doesn't usually cause symptoms and is usually only found during an X-ray or MRI for another problem. A variety of monitoring, therapies, and surgeries are used to treat spina bifida. Adequate folic acid taken by the mother during pregnancy is a know way to try to prevent the disorder.
Ventricular Septal Defect Ventricular septal defect is a congenital heart condition in which there is a hole in the wall separating the ventricals, the two lower chambers of the heart. The hole allows oxygenated blood to mix with unoxygenated blood and recirculate. Left untreated by corrective surgery, this can cause the heart to work so hard it fails, along with a host of other problems including pulmonary hypertension.
