1. atrial septal defect

   An atrial septal defect is a congenital (present at birth) heart defect characterized by a hole in the wall (septum) that separates the two upper chambers (atria) of the heart. This condition allows oxygen-rich blood to leak from the left atrium into the right atrium, instead of flowing into the ventricle and then out to the rest of the body. This defect may lead to enlargement and damage of the heart, cause abnormal heart rhythms, and increase the risk of stroke and heart failure.

1. Atrial septal defect

   Atrial septal defect is a form of congenital heart defect that enables blood flow between two compartments of the heart called the left and right atria. Normally, the right and left atria are separated by a septum called the interatrial septum. If this septum is defective or absent, then oxygen-rich blood can flow directly from the left side of the heart to mix with the oxygen-poor blood in the right side of the heart, or vice versa. This can lead to lower-than-normal oxygen levels in the arterial blood that supplies the brain, organs, and tissues. However, an ASD may not produce noticeable signs or symptoms, especially if the defect is small. A "shunt" is the presence of a net flow of blood through the defect, either from left to right or right to left. The amount of shunting present, if any, determines the hemodynamic significance of the ASD. A "right-to-left-shunt" typically poses the more dangerous scenario. During development of the fetus, the interatrial septum develops to separate the left and right atria. However, a hole in the septum called the foramen ovale, allows blood from the right atrium to enter the left atrium during fetal development. This opening allows blood to bypass the nonfunctional fetal lungs while the fetus obtains its oxygen from the placenta. A layer of tissue called the septum primum acts as a valve over the foramen ovale during fetal development. After birth, the pressure in the right side of the heart drops as the lungs open and begin working, causing the foramen ovale to close entirely. In approximately 25% of adults, the foramen ovale does not entirely seal. In these cases, any elevation of the pressure in the pulmonary circulatory system can cause the foramen ovale to remain open. This is known as a patent foramen ovale, which is a type of atrial septal defect.
