2. Figure 1
This M-mode echocardiogram demonstrates the right ventricle (RV), the interventricular septum (VS), left ventricular cavity (LV), and posterior left ventricular wall (PW). The black arrows point to echoes from a chaotic, randomly-moving extruded disc from a Beall mitral valve prosthesis in the left ventricular cavity.

3. Figure 2
Four individual frames of an apical four-chamber view are presented demonstrating the right ventricle (RV), left ventricle (LV), right atrium (RA), left atrium (LA), interatrial septum (as), and interventricular septum (vs). The white arrows point to an extruded disc from a Beall mitral valve prosthesis that is visualized in different areas within the left ventricular cavity in these serial images.

4. Figure 3
The extracted Beall mitral valve prosthesis demonstrates no evidence of strut malfunction as the cause of the missing disc.
