摘要：

A 74-year-old man, who had a history of a mitral valve replacement for rheumatic heart disease (RHD) 30 years previously, was admitted with progressive heart failure. Massive calcification was observed around the left atrium on multidetector CT, in addition to a late gadolinium enhancement (LGE)-positive layer adjacently outside of the calcification on MRI. He underwent a second mitral valve replacement for the prosthetic valve failure. Pathohistological analyses of a tissue section of the left atrial wall from a surgical specimen revealed lymphocyte and macrophage infiltration that coincided with the LGE-positive layer on MRI, suggesting the existence of sustained active inflammation even after the long period of RHD.
