Distal SVC = Distal superior vena cava

RA = Right atrium

RV = Right ventricle

PV = Pulmonary vein

LA = Left atrium

Top of LV = Top of left ventricle

Ao Root = Aortic root



The area of decreased signal intensity in the right ventricle near the RV outflow tract (between arrowheads) is a flow jet representing blood flowing in a different direction from the rest of the blood in the RV (which is white). In this case the flow jet represents blood from the left ventricle coursing through the ventricular septal defect to the right ventricle and pulmonary artery.
