TEE showed a structure attached to the atrial surface of the anterior (A2, A3 component) leaflet of the mitral valve (Figure 1), most consistent with a left atrial fibrous band.
3D live imaging of the left atrial fibrous band.

The band appeared to restrict the motion of the A2, A3 component with consequent MR, giving it a tented appearance, while 3D live imaging allowed for complete visualization of the band attaching to the mitral valve (Figure 2).

Intraoperative findings included mitral valve prolapse (MVP), thickened fibrous mitral valve, and MR (Figure 3).
