A D-shaped left ventricle or flattening of the interventricular septum with a D-shaped configuration is a feature described with significant right ventricular (RV) overload / right heart strain such as that occurring with complications of a sizable pulmonary embolic event. It was initially described in SPECT / scintigraphic studies although similar appearances have also been described in echocardiography¹and CT scans in similar situations.
