Note the thin chordae tendineae (arrows) extending to the anterior and posterior mitral valve leaflets. (b) Contrast-enhanced CT scan of the heart shows a modified long-axis view of the posterior papillary muscle (P) and chordae tendineae (arrows). (c) Reformatted image of the left ventricle from CT data shows a modified short-axis view of the anterior (A) and posterior (P) papillary muscles.
