Evaluation of causal heart diseases in cardioembolic stroke by cardiac computed tomography

Figure 13  Mechanical mitral valve dysfunction. An 86-year-old woman who had undergone St. Jude Medical 29 mm-sized mitral valve replacement 17 years earlier and now presented with congestive heart failure underwent non-contrast cardiac computed tomography (CCT) to evaluate the etiology of mitral regurgitation observed on transthoracic echocardiography. A and B: Multiplanar reformatted images perpendicular to valve leaflet (A) and short axis images (B) of non-contrast CCT show incomplete opening of bileaflet mechanical mitral valve (arrows).
