Dilated right ventricle

Tips Dilated right ventricle is best seen in PSAX and A4CH

In the context of suspected pulmonary embolism, ultrasound can provide crucial diagnostic information by assessing right ventricular (RV) dilation. A dilated RV suggests increased pressure in the pulmonary arteries, often caused by a pulmonary embolism obstructing blood flow to the lungs. Key ultrasound findings include an enlarged RV compared to the left ventricle (LV), abnormal septal motion, and in some cases, visible clot or poor RV function.

Right Ventricular Dilation: The RV appears larger than the LV, indicating pressure overload.

Septal Flattening or Paradoxical Motion: The interventricular septum may bow towards the LV due to increased RV pressure.

McConnell’s Sign: A specific pattern of RV dysfunction where the apex contracts normally while the free wall is hypokinetic, seen in some cases of pulmonary embolism.

Normal RV Size and Function: The RV should not appear larger than the LV, and the septum should remain in a normal position.
