Interventricular septum aneurysm is a rare, non-syndromic, congenital heart malformation characterized by the presence of a congenital aneurysm of the membranous portion of the interventricular septum.

Ventricular septal defects and conduction defects, such as first-degree atrio-ventricular block or incomplete right bundle branch block, may also be also associated.
