The 3D rendering of the heart showing the calcified area of the valve. A Coronal view showing the area covered by calcification, indicating obvious calcification of the aortic valve and mitral valve, with a wide range of involvement. B Sagittal view showing the relationship between the calcified valve and pulmonary artery and vein, as well as the depth of calcification invasion, which is difficult to determine intraoperatively.
