Brain ischemia. Brain ischemia (a.k.a. cerebral ischemia, cerebrovascular ischemia) is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. This leads to poor oxygen supply or cerebral hypoxia and thus to the death of brain tissue or cerebral infarction / ischemic stroke.
Most congenital heart defects affect how blood flows through the heart or through the blood vessels near the heart. Some defects may cause blood to flow in a pattern that isn't normal. Others can completely or partially block blood flow. There are many different types of congenital heart defects. They can be fairly simple, such as a hole between the chambers of the heart or a heart valve that has not formed right. Others are more serious and complex, such as a missing heart valve or heart chamber.
