Key result
The 3DE longitudinal axial plane method showed excellent correlation with the short-axis disc summation method for RVEDV, RVESV, and RVEF (r = 0.99, 0.99, and 0.94; P<0.0001).
Why the study?
Does the 3DE longitudinal axial plane method accurately measure RV volumes and function compared to the short-axis disc summation method in subjects with a broad range of RV function?

May facilitate RV assessment when short-axis views are suboptimal; leaves open prospective validation before practice change.
Observational (n=40)
Does the 3DE longitudinal axial plane method accurately measure RV volumes and function compared to the short-axis disc summation method in subjects with a broad range of RV function?
Effect estimate: r = 0.99, 0.99, 0.94
p-value: p=<0.0001
The 3DE longitudinal axial plane method provides an accurate alternative for assessing right ventricular volumes and function, which may be particularly useful when short-axis images are suboptimal.
Endo et al. (2006) conducted an observational in Broad range of right ventricular function (n=40). 3DE longitudinal axial plane method vs. 3DE short-axis disc summation method was evaluated on Correlation of RVEDV, RVESV, and RVEF between methods (r = 0.99, 0.99, 0.94, p=<0.0001). The 3DE longitudinal axial plane method showed excellent correlation with the short-axis disc summation method for RVEDV, RVESV, and RVEF (r = 0.99, 0.99, and 0.94; P<0.0001).
