What symptom does foramen ovale not close have

summary

If the foramen ovale is not closed and not treated in time, it will also have a great impact on us. "The foramen ovale was not closed when we were born, and now we are more than three years old. The doctor suggested that we should have a look in half a year, and the child's weight is only 13.4 kg, will it be related to the foramen ovale?" many parents are worried about whether the foramen ovale is not closed in the future.

What symptom does foramen ovale not close have

First, if only the foramen ovale is not closed, and there is no other heart disease, we should not worry too much, but we must make sure that the child has no other problems. Patent foramen ovale alone should not affect his development. Please pay attention to whether his lips turn purple and blue when he is exercising or crying. If there are any, they should be checked in detail.

Second, when we are born and know how to breathe by ourselves, the pumping pressure of the left atrium is higher than that of the right atrium, and the foramen ovale, which is located in the upper part of the heart, that is, the small door on the left atrium and the right atrial septum, will be closed. As time goes by, fibrous tissue grows on the foramen ovale, which further seals the door to keep it closed. In this way, the hypoxic blood flowing through the right atrium is completely separated from the oxygen filled left atrium. With the help of the left atrium, the oxygen filled blood can be smoothly pumped to the whole body to provide oxygen. Foreign studies have pointed out that about 25 to 30% of the people have this small door, not completely closed, known as "patent foramen ovale.".

Third, patent foramen ovale has a great influence on some people. The reason is that the hypoxic blood flowing through the right atrium will flow to the left atrium through this small gate and mix with the blood full of oxygen there. In this way, the oxygen content of the blood pumped through the left atrium to the whole body will decrease.

matters needing attention

If the blood from the right atrium has blood clots (thrombus), they will also be pumped directly to the brain by the left atrium, leading to cerebrovascular embolism and stroke. Blood clots may also form in the unclosed foramen ovale and migrate to the left atrium and upper brain, resulting in stroke.
