Overview

(ASD) are a group of congenital heart diseases that involve the inter-atrial septum. The inter-atrial septum is the tissue that separates the right and left atria from each other. This tissue prevents arterial and venous blood from mixing with each other. If there is a defect in this septum, a direct communication between the atria can occur, which allows shunting, resulting in mixing of arterial and venous blood. It is possible for blood to travel from the left side of the heart to the right side of the heart, or vice versa.

Epidemiology and demographics

Atrial septal defect are common heart defects and comprises approximately 7% of all the congenital heart disorders. ^[1]. Unlike other conditions ASD has a slight female preponderance of 2:1.

-==Overview==
-'''Atrial septal defects''' (ASD) are a group of [[congenital heart disease | congenital heart diseases]] that involve the inter-atrial septum. The inter-atrial septum is the tissue that separates the [[right atrium|right]] and [[left atrium|left]] atria from each other.  This tissue prevents arterial and venous blood from mixing with each other. If there is a defect in this septum, a direct communication between the atria can occur, which allows shunting, resulting in mixing of arterial and venous blood. It is possible for blood to travel from the left side of the heart to the right side of the heart, or vice versa.
-The direction of shunting will depend on a variety of factors, notably the patient's [[hemodynamics]].  If the pressures are higher in the right atrium than the left atrium, blue cyanotic blood will flow from the right atrium into the lower pressure left atrium.  A "Right-to-left-shunt" as described above may pose a more dangerous scenario (See [[Atrial septal pathophysiology | Pathophysiology]] below).  Since the right side of the heart contains venous blood with a low oxygen content, and the left side of the heart contains arterial blood with a high oxygen content, right to left shunts can cause [[hypoxia]] and result in [[cyanosis]].  Additionally, a communication between the two atria may allow blood clots to pass from the venous system to the arterial system and result in a [[stroke]] or peripheral embolism.
