Abstract

A 69-year-old female underwent cardiac CT to evaluate prosthetic valve (PHV) dysfunction detected on echocardiography. A CT coronal and en face views of the mitral annular plane showed a low-density, mass-like lesion on the left atrial side of the PHV and a high-density, plate-like lesion on the left ventricular side of PHV. A repeat of the mitral valve replacement was performed, and preoperative CT findings of both the thrombus on the left atrial side and pannus formation on the LV side were confirmed in the operative findings.
