3 Fig 2 Diagram and noncontrast enhanced computed tomography scans showing extensive mitral annular calcification (MAC) and insertion of a no. 31 St. Jude Epic mitral valve bioprosthesis. (A) Left lateral view (two-chamber) of the heart with extensive MAC, cut through the left atrium and left ventricle showing a mitral valve bioprosthesis with fixating pledgets passed into the native uncalcified coronary sinus (CS). (B) Long-axis view of the left ventricle showing MAC, bioprosthesis, and pledgets within the CS. (C) Short-axis view through the atrioventricular junction showing extensive MAC surrounding the titanium ring of the mitral valve bioprosthesis. (D) Short-axis view of the mitral valve showing the titanium ring of the bioprosthesis and two pledgets attached on the roof of the CS.
