case_images: A transthoracic echocardiogram (TTE) revealed a dilated LV with an ejection fraction of 56% and moderate-to-severe eccentric aortic regurgitation secondary to leaflet malcoaptation (Fig. 1).
case_images: Left ventricular outflow tract views showing the subaortic aneurysm (blue arrow) compressing the left atrium (red arrow, left) and sparing the left coronary artery (right).

case_images: Due to suboptimal imaging on TTE and TEE, a cardiac MRI was requested to confirm the SA aneurysm and to define with certainty its relationship to the surrounding structures (Fig. 2).
case_images: Left ventricular outflow tract (left) and short-axis views (right) depicting compression of the left atrium (blue arrow) by the sub-aortic aneurysm (red arrow).

case_images: A 30 x 14-mm aneurysm with a 12-mm neck was noted below the aortic valve, which extended to the LA roof (Fig. 3).
case_images: Left ventricular outflow tract MRI image showing an aortic regurgitant jet (arrow) secondary to retraction of the left coronary cusp by the sub-aortic aneurysm.
