Under normal circumstances, the secondary hole will close after the child is born. After the child is born, the left atrium pressure is greater than the right atrium, and directly press the patch on the hole to erase the hole.

It's a fear of where it is. Some people have too big defects, not big enough patches, and cannot cover them, and cannot be closed or completely removed. Such people account for a certain proportion of the crowd, and they are not low, and can account for two percent.

Thirty. Another major disease of atrial septal defect occurs here, called secondary atrial septal defect.

After hearing this, some people can't believe that so many people suffer from this disease, because they rarely hear about such patients around them.

This is because most of these people have very small pores that basically do not affect the hemodynamics of the heart. Patients have no symptoms and have not been found for medical treatment. They do not affect human health. Medically, they believe that there is no need for intervention. What is nothing to do?

Go and get a knife, right?

People who need surgery have symptoms. This symptom is based on the large area of ​​the defect, and too much blood is poured into the right atrium from the left atrium, which causes pulmonary artery hypertension. Continuous pulmonary artery hypertension will evolve into organic pulmonary artery lesions, which will make the right

The blood in the atrium is pressed into the left atrium and the left ventricle, causing left heart failure and cyanosis. This kind of evolution is called Eisenmanger syndrome. At this point, we know from previous cases that it is very troublesome, and only lung transplantation can be achieved.

If surgery is required, it is necessary to detect and solve it in time. The problem is that electrocardiograms or chest radiographs of this type of disease need to be detected until pulmonary hypertension or arrhythmia occurs.

Even if the defect area is large, this type of patient is at most susceptible to colds in childhood, and no other significant symptoms are found, and ordinary physical examination items cannot be found.

When you are adolescents, some symptoms appear, which are more likely to breathe than ordinary people.

We Chinese like to classify these patients as physically weak, and never thought that there would be organic diseases. The main reason is that the examination items are too simple and incorrect, and the necessary screening cannot be done.

This type of patient can continue to live without severe pulmonary hypertension. After the age of 40, the symptoms will become more and more serious. At that time, the examination will finally be found and you will know that you will have to do a color ultrasound. If the pulmonary hypertension misses the timing of the operation, your life span will be long

Abandoned a decade or two.

For treatment, there is an option for interventional closure after interventional surgery. Like other interventional surgery, interventional surgery has conditions and thresholds. If the location of the defect is not good, the shape of the defect is strange and complicated, interventional surgery

It's impossible to do it, so you can only choose to go to surgery.

The incidence rate of men and women in this disease is more than twice that of men.

The girl in bed 12 was admitted to the hospital. The echo loss was visible in the central part of the room septum, about 30mm in size, and the colored blood flow showed the left-right diversion of the room level. The defect was large, the edges were uneven, and the intervention could not be performed in surgery.

Most of the heart surgery was performed in two cases of median sternum incisions performed before. Today, I heard from teachers that the incision on the right side of the chest may be taken.

In the early stage of open heart surgery, the side incision was actually taken. Later, it was found that the sternum exposure was very convenient for doctors to operate. Some very complicated heart diseases can only be performed by incision of the sternum.

In modern times, the right incision has returned to the cardiac surgery industry again. This is because doctors found that it is not very complicated to continue using the right incision, and the surgical scars left by the incision under the armpit are easily hidden and hung down.
