title: [Cardioembolic stroke due to mitral annular calcification with a mobile component].
abstract: We report here a 50-year-old man on maintenance hemodialysis who presents right hemiparesis, aphasia. MRI diffusion weighted image showed an increased signal intensity in the area of the left middle cerebral artery. Transthoracic and transesophageal echocardiography revealed a mitral annular calcification (MAC) with a mobile component. After treated with heparin, follow-up echocardiography demonstrated a decrease in the size of the mobile component, but not disappeared. Intraoperative findings showed calcified attachment on the posterior mitral valve. This patient was diagnosed as having cardioembolic stroke due to a MAC with a mobile component.
