Saddle Pulmonary Embolus Caught in Transit across a Patent Foramen Ovale

Figure 2

CTPA showing saddle PE (a), intracardiac thrombus extending from RA to LA through PFO (b) and further prolapsing into the left ventricle through mitral valve leaflets (c): all axial reconstruction. The same clot in sagittal view ((d), inside the red circle) and coronal view (e). RV enlargement relative to LV compressing the LV in characteristic “D shaped” pattern ((f), double arrows) all consistent with RV strain.
