PSAX view demonstrating the grossly dilated RV above the contracted and small volume LV indicating severe reduction in LV filling.
Subcostal view demonstrating dilated RV and RA above small LV and LA.
A subsequent CTPA (images below) demonstrated bilateral main pulmonary artery emboli and RV dilation.
