Atrial septal defects are a group of rare disorders of the heart that are present at birth and entail a hole in the wall that divides the two upper-chambers of the heart. Normally the heart has 4 chambers: two top chambers understood as atria that are divided from each other by a fibrous dividing known as the atrial septum and two lower chambers referred to as ventricles that are separated from each other by the ventricular septum. In infants with atrial septal defects, the atrial septum might not shut effectively or might be deformed throughout fetal growth. Regularly, the shutoffs that separate the atria from their respective ventricles are also misshaped, and the septum that separates the ventricles might additionally be malformed or lacking. Among the major capillaries of the body that returns blood to the heart might additionally be deformed. Most children with atrial septal defects have no symptoms. A heart whispering is the most common sign and usually the only sign of ASD in children. There might additionally be a change in heart seems that stands for the closing of the shutoffs of the heart. Around the age of 40 years, people with atrial septal defects may experience symptoms associated with an increase in pressure in the capillary of the lungs. Extreme cases of atrial septal defects might lead to serious complications such as upper body pain, irregular heart beats, abnormal enlargement of the heart, a fluttering of the heart, and/or heart failure. Women with atrial septal defects that end up being pregnant might go to risk for episodes of blood clot formation.
