33-year-old man with bicuspid aortic valve and aortic insufficiency. Coronal oblique MRI (bSSFP sequences) through the LVOT shows a small aneursymal out-pouching of the IVMS (arrow). Systolic image (a) shows dephasing artifact associated with a post-stenotic jet from aortic stenosis in a bicuspid valve, while a diastolic image (b) shows an eccentric regurgitant jet (small arrow) directed towards the IVMS aneurysm
