Variable size of aortic subvalvular pseudoaneurysm.

ABSTRACT: Aortic subvalvular pseudoaneurysms (PSA) are particularly subjected to strain and shear stress forces from blood flow and therefore their size can vary along the heart cycle. Here we describe a case of an aortic subvalvular PSA that shows significant variation in size between systolic and diastolic phase during retrospective ECG-triggered cardiac computed tomography angiography.
