ANSWER 1: B. The 3D TEE video shows the mitral valve from the left ventricular perspective. The myxoma enters the left ventricle during diastole.

In the M-mode image (Fig. 19-2), the mitral valve (A) is seen (arrow), and the myxoma (B) prolapses into the mitral orifice with each diastole.






Figure 19-2.
