Ce trou amène le sang riche en oxygène à fuir du côté gauche du cœur vers le côté droit. Cela cause un travail supplémentaire pour le côté droit du cœur, étant donné que plus de sang que nécessaire circule du ventricule droit vers les poumons. </p><h2> À retenir </h2> <ul><li>La communication interauriculaire est un trou dans la paroi qui divise le septum auriculaire (les cavités supérieures du coeur); ce trou amène le sang riche en oxygène à fuir du côté droit du cœur.</li> <li>La communication interauriculaire est habituellement accompagnée de peu de symptômes.</li> <li> La plupart des enfants atteints d’une communication interauriculaire réparée pendant l’enfance par cathétérisme cardiaque ou une chirurgie à coeur ouvert peuvent s’attendre à avoir une espérance de vie normale. </li></ul>

Tests to help diagnose ASD include chest X-ray, electrocardiogram, and echocardiogram. </p><p>ASDs make up 6% to 10% of all heart abnormalities, and occur in one child per 1,500. </p> <figure class="swf-asset-c-80"> <span class="asset-image-title">Atrial septal defect</span> <div class="asset-animation"> src="https://akhpub.aboutkidshealth.ca/Style%20Library/akh/swfanimations/swf.html?swffile=Atrial_septal_defect_MED_ANI_EN.swf" </div> <figcaption class="asset-image-caption">A hole in the wall dividing the upper chambers of the heart results in oxygen-rich blood leaking into the right atrium.</figcaption> </figure> <h2>What are the symptoms of atrial septal defect?</h2><p>Because the heart is usually able to compensate for this defect, there are usually few symptoms. In about 40% of cases, the hole closes on its own before the age of two. When this does not happen, there are two methods that may be considered to close the hole:</p><ul><li>Many holes can be closed with a device during a cardiac catheterization.</li><li>If the hole is very large or is located close to a valve, open heart surgery is done to close the hole using sutures or a patch. </li></ul><h2>What is the long-term outlook for children with atrial septal defect?</h2><p>Research indicates that children with ASD that is diagnosed and repaired in childhood are expected to live as long as would be expected for an average person. </p><p>Those who are diagnosed and treated after the age of 25, however, do not fare quite as well. There is a small risk of sick sinus syndrome or arrhythmia. </p>Atrial septal defect (ASD)
