Right ventricular size calculator and measurement guide
Browse right ventricular dimensions, area, RVOT and wall measurements, and 3D volume methods within the existing RV size tool.
Method
Indexed measurement = measured dimension, area or 3D volume ÷ BSA
Use the measurement units shown below. Some fields apply only to a selected method or condition; follow the interactive tool’s method choices. The interactive tool keeps missing measurements incomplete and provides its method-specific results and reference context.
