TRUFI image in the LVOT plane shows the pseudoaneurysm (delineated by open arrows) between aortic root and left atrium with relatively hypointense signal (due to dephasing secondary to turbulence)

The aneurysm was seen filling during the systole and emptying during the diastole and showed a swirling flow (manifested by hypo intense signal secondary to rapid dephasing due to turbulent flow); the aortic valve was bicuspid with severe aortic regurgitation and thickening of valve margins [Figure 1 and Videos 1 and 2].

The aneurysm was seen filling during the systole and emptying during the diastole and showed a swirling flow (manifested by hypo intense signal secondary to rapid dephasing due to turbulent flow); the aortic valve was bicuspid with severe aortic regurgitation and thickening of valve margins [Figure 1 and Videos 1 and 2]. MRI when the lesion measured 1.7 x 2.5 x 2.7 cm in the same cardiac phase) arising from left ventricular outflow tract below the aortic annulus; the aneurysm was related anteriorly to the aortic root and posteriorly to left atrium [Figures 2 and 3]. Multiphasic images revealed that the aortic valve was bicuspid with thickening of the free edges of the valve and dilation of ascending aorta (measuring 3.9 x 3.9 cm).
