Bicuspid aortic valve with regurgitation and minimal restriction of motion. a Diastolic image in short axis of the aortic valve demonstrates a linear closure of the aortic valve with only two leaflets (arrowheads). A small regurgitant orifice is visible between the mildly thick leaflets. The more anterior leaflet is in the position that would typically be occupied by the right and left coronary leaflets. b Systolic image in short axis of the aortic valve demonstrates a “fish-mouth”-shaped opening of the two leaflets (arrowheads) that is typical for a bicuspid valve. The overall aortic valve area is minimally restricted (2 cm² by planimetry)
