Multimodality imaging evaluation of multilobulated subvalvular aortic aneurysm involving the membranous ventricular septum.

We report a rare clinical case of multilobulated subvalvular aortic aneurysm located in the left ventricular outflow tract, involving the membranous ventricular septum, and associated with mild prolapse of the noncoronary aortic leaflet, emphasizing the importance of multimodality imaging approach, and multidisciplinary discussion.
