Rajagopal et al., Ped Card 2018
BSA-adjusted z-scores of right atrial area, measured using planimetry/tracing. Areas are adjusted for body size using allometric equations (allometric exponents are different for children on either side of 1m2).
We hope that this study will pave way for a gradual paradigm shift to more quantitative approaches for the assessment of RA size and allow clinicians to better incorporate assessment of the right heart into an echocardiographic evaluation.

Note: the study population had the following characteristics:
- age range: (0 - 18)
- bsa range: (0.19 - 2.05)
Data entered for patients outside of these limits should be used with caution.
