Key result
Tissue Doppler imaging measurements of the right heart, including E/e' ratio (r=0.44), significantly correlated with invasively measured central venous pressure in pediatric subjects.
Why the study?
Do Tissue Doppler imaging measurements correlate with invasively measured central venous pressure in pediatric patients after cardiac surgery?
Population
28 pediatric patients younger than 10 years with invasive CVP monitoring after cardiac surgery
Comparison

May support noninvasive CVP estimation post-pediatric cardiac surgery; leaves open prospective validation before practice change.

Do Tissue Doppler imaging measurements correlate with invasively measured central venous pressure in pediatric patients after cardiac surgery?
Effect estimate: r = 0.44 for E/e' ratio
Tissue Doppler imaging measurements of the right heart significantly correlate with invasively measured CVP in pediatric patients after cardiac surgery, suggesting its potential as a noninvasive assessment tool.
Learn et al. (2010) conducted an observational in Pediatric patients after cardiac surgery (n=28). Tissue Doppler imaging (TDI) vs. Invasive central venous pressure (CVP) monitoring was evaluated on Correlation between TDI measurements and CVP (r = 0.44 for E/e' ratio). Tissue Doppler imaging measurements of the right heart, including E/e' ratio (r=0.44), significantly correlated with invasively measured central venous pressure in pediatric subjects.
