RV dilatation/Hypokinesis
• In the apical 4 chamber view, a ratio RVEDA (area) to LVEDA > 0.6 correlates with moderate RV dilatation.
• A ratio > or = 1.0 correlates with major RV dilatation.

Septal Flattening
• Right ventricular pressure overload leads to deviation of the interventricular septum towards the LV in diastole.
• Interventricular septalflattening is seen during systole creating a so-called D-shaped LV.

Regional RV-Dysfuntion in Acute PEMcConnell,s Sign
• RV dysfunction on echocardiography has been reliably established as a predictor of adverse outcomes in PE.
• The most commonly accepted quantitative standards are:
1. RV to LV end-diastolic diameter ratio > 1 in the apical 4-chamber view
2. RV end-diastolic diameter > 30 mm
3. Paradoxical interventricular septalsystolic motion
