Under normal circumstances, the pore secundum will close after the child is born. After the child is born, the pressure in the left atrium is greater than that in the right atrium. Simply press the patch onto the hole to erase the hole.
What I'm afraid of is that for some people, the defect is too long and the patch is not big enough, so it cannot be covered or closed completely. Such people account for a certain proportion of the population, and it is not low, accounting for 2%.
30. Another major type of atrial septal defect occurs here, called secundum atrial septal defect.
Hearing this, some people couldn't believe that there were so many people suffering from this disease, because it was rare to hear of such patients around.
This is because the pores of most of these defects are very small and basically do not affect cardiac hemodynamics. The patients are asymptomatic and have not been discovered without seeking medical treatment. The discovery does not affect human health. Medically speaking, it is considered that no intervention is needed. What are you doing if you have nothing to do?
Going to get stabbed, right?
People who need surgery have symptoms. This symptom is due to the large defect area and too much blood pouring from the left atrium into the right atrium, causing pulmonary hypertension. Sustained pulmonary hypertension will evolve into organic pulmonary artery disease, causing the right
The blood in the atrium is re-pressurized into the left atrium and left ventricle, causing left heart failure, cyanosis and other symptoms. This evolution is called Eisenmenger syndrome. At this point, we know from previous cases that it is very troublesome, and the only option is lung transplantation.
If surgery is required, it must be detected as early as possible and solved promptly. The problem is that electrocardiogram or chest X-ray of this type of disease cannot be detected until pulmonary hypertension or arrhythmia occurs.
Even if the defect area is large, such patients will most likely show cold-like symptoms in childhood, with no other obvious symptoms and cannot be detected by ordinary physical examination items.
When I reached adolescence, some symptoms appeared, and I was more likely to be short of breath than ordinary people.
Our Chinese people like to classify such patients as having a weak constitution, and never thought that there might be organic diseases in them. The main reason is that the examination items are too simple and inappropriate, and the necessary screening cannot be carried out.
This type of patient can continue to live before severe pulmonary hypertension occurs. The symptoms will become more and more severe after the age of forty. At that time, the test will finally find out and they will know that they need to have a cardiac ultrasound. If the opportunity for surgery is missed for pulmonary hypertension, the life expectancy will be
Lose ten or twenty years.
For treatment, interventional closure is an option due to interventional surgery. Like other interventional surgeries, interventional surgery has conditions and thresholds. If the location of the defect is not good, and the shape of the defect is strange and complicated, interventional surgery is not recommended.
It can't be done, so the only option is surgery.
The male-to-female incidence ratio of this disease is more than double that of males.
A 12-bed girl, the admission examination showed that the echo was lost in the central part of the atrial septum, the size was about 30mm, and the colored blood flow showed left-right shunting at the atrial level. The defect was large and the edges were uneven, so interventional surgery could not be performed.
Most of the cardiac surgeries were performed through the midline sternal incision in the two previous cases. Today I heard the teachers discussing in a low voice that the right side of the chest, under the armpit, and the lateral chest incision may be used.
In the early days of open heart surgery, lateral incision was actually used. Later, it was discovered that incision through the sternum was very convenient for doctors to expose the surgical field. Some very complex heart diseases could only be performed through incision through the sternum.
In modern times, right-sided incisions have returned to the heart surgery community again. This is because doctors have found that there is no problem in using right-sided incisions for less complex heart diseases, and the surgical scars left by the incisions under the armpits are easy to hide and are hung down.
The arms are covered, which is in line with the patient's pursuit of beauty.
