Aneurysm of the Interatrial Septum
The Common Vein Copyright 2008
Introduction
An aneurysm of the interatrial septum occurs both congenital as well as acquired conditions. In diseases such as mitral atresia and tricuspid atresia blood is forced through the atrial septum and if the septum primum is restrictive then bulging of the septum occurs and over a long period this becomes an aneurysm. A pathological specimen of an aneurysm of the interatrial septum and mitral atresia is demonstrated below.

In image b, the light green overlay represents the aneurysm while to the right of the image in red is the left atrium, and to the left of the image (patients right) the tricuspid valve is overlaid in blue.
