Figure legends:
Figure 1 A-C. Preoperative thorax CT-scan showing the
previously implanted prosthetic mitral valves (red arrows) and the
surrounding extensive annular calcification (yellow arrows). Atransversal view, B coronal view, C sagittal view.Ao Aorta, LA left atrium, LV left ventricle,PA pulmonary artery, RA right atrium, RVright ventricle, SVC superior vena cava.
Figure 2 A–C Degenerated mitral “valve-in-valve” prostheses.
Note the severe stenosis demonstrated by the inability of the leaflets
to sufficiently open (yellow arrow). A lateral view, Bview from ventricular aspect, C view from atrial aspect.Figure 2D Calcified tissue removed during operation.

patch for reconstruction of the posterior aspect of the mitral annulus
(blue arrow).
