Interventricular membranous septal aneurysm: CT and MR manifestations

Abstract

Advanced cardiac imaging is a valuable method to investigate cardiac malformations. The detection of the interventricular membranous septum has clinical significance due to thrombogenic and arrythmogenic predisposition, as well as a role in obstructing the pulmonary flow. This review describes six clinical presentations in which advanced cardiac imaging has been the tool for evaluation, with special emphasis in CT angiography and cardiac MRI sequences.

Teaching Points

• The interventricular membranous septum can predispose patients to thrombogenic and arrythmogenic events.

• Subpulmonic stenosis relates to the protrusion of the aneurysm into the right ventricle

• During surgery, ventricular pressures of the opened heart become balanced, making the aneurysm less evident.
