• RV size should be routinely assessed by conventional 2DE using multiple acoustic windows, and the report should include both qualitative and quantitative.
• In general, a diameter >41 mm at the base and >35 mm at the mid-level in the RV-focused view indicates RV dilatation.
• In laboratories with experience in 3DE, when knowledge of RV volumes may be clinically important, 3D measurement of RV volumes is recommended.
• Although normal 3D echocardiographic values of RV volumes need to be established in larger groups of subjects, current published data suggest RV EDVs of 87 mL/m2 in men and 74 mL/m2 in women, and RV ESVs of 44 mL/m2 for men and 36 mL/m2 for women as the upper limits of the corresponding normal ranges.
