Discussion

Aneurysms of the membranous of interventricular septum are relatively rare lesions and are probably of congenital origin as is in the current case. There is now evidence to suggest that aneurysms may develop in the course of spontaneous partial or complete closure of ventricular septal defects (VSDs), although their exact anatomic basis is controversial [1]. Some studies have reported that aneurysm formation is associated with diminution in the functional size of membranous VSDs, and considered that the formation of aneurysms of the membranous septum is one mechanism of closure of VSD [2].
