case_images: Cardiac CT of aortic valve chordae tendineae. Multi-planar reformatted image (A) and volumetric 3D display (B) of the LVOT and aortic root with a notably calcified aortic valve and fibrous strand (arrow) tethering the non-coronary cusp to left ventricular outflow tract. A right coronary cusp cut-away of a 3D STL display (C) shows a longitudinal view of chordae (teal) with aortic calcifications (yellow). A subvalvular projection of the aortic valve (D) visualizes the fibrous strand attachments to the non-coronary cusp and LVOT.

case_images: A cardiac CT was performed, and cinematic 4D display noted a fibrous strand tethering the non-coronary cusp of the tricuspid aortic valve to the LVOT, creating functional aortic stenosis (Fig. 1). Multi-planar reformatted imaging (Fig. 1A) and volumetric 3D display (Fig. 1B) of the LVOT and aortic root revealed the fibrous strand, not previously visualized on TTE or TEE (Fig. 2).
case_images: Mid esophageal TEE of aortic valve: Tricuspid heavily calcified aortic valve visualized in early systole (A) and diastole (B) on mid esophageal short axis view.
