Intraoperative pre-procedural TEE imaging. A real-time 3D Zoom “en face” image of the AV, seen from an aortic perspective, confirmed a bicuspid AV (a). Rendered and rotated enface images with built-in 3D-grids (dot-to-dot distances of 2 and 5 mm) focused on the left main and right coronary ostia (yellow arrows) revealed their high take-off with distances less than 3 mm from the STJ (red dot circles) (b and c). Additional multi-planar cut (tomographic) images with a different axis, rendered from the 3D dataset of the AV using 3DQ software in QLAB™ (Philips Healthcare, Bothell, WA), confirmed the short distance of 2 ~ 3 mm from the STJ to the RCA and left main ostium (d). Ao, aorta; AV, aortic valve; LA, left atrium; LM os, left main coronary ostium; LV, left ventricle; RA, right atrium; RCA os, right coronary ostium
