The IAS in the context of heart disease refers to the inter-atrial septum, which is a crucial structure within the heart.
Understanding the Inter-atrial Septum (IAS)
- Definition: The inter-atrial septum (IAS) is a thin wall located between the right and left atria of the heart.
- Function: The IAS separates the two atria, preventing the mixing of oxygenated and deoxygenated blood.
IAS Motion and Heart Function
Normally, the IAS moves slightly, either towards the left or right atrium. This motion is influenced by the pressure difference between the two atria. Problems with the IAS and its movement can indicate underlying heart conditions.
