CMR. End-diastolic (panels A, C,), and end-systolic (panels B, D) images in the two-chamber and four-chamber orientations, from a free-breathing gradient-echo cine CMR sequence. There are numerous saw-tooth like muscular projections originating from the inferior LV wall, some of them being tethered to the interventricular septum. These myocardial projections have a circular architecture, like successive open rings at the inferior half of the ventricle, spanning the entire heart from the base to the apex.
