Abstract:
Background: Right atrial pressure (RAP) can be estimated by echocardiography from inferior vena cava diameter and collapsibility (eRAP IVC ), tricuspid E / e ′ ratio ( eRAP E / e ′ ), or hepatic vein flow (eRAP HV ). The mean of these estimates (eRAP mean ) might be more accurate than single assessments. Methods and Results: eRAP IVC , eRAP E / e ′ , eRAP HV (categorized in 5, 10, 15, or 20 mmHg), eRAP mean (continuous values) and invasive RAP (iRAP) were obtained in 43 consecutive patients undergoing right heart catheterization [median age 69 (58–75) years, 49% males]. There was a positive correlation between eRAP mean and iRAP (Spearman test r = 0.66, P & lt; 0.001), with Bland–Altman test showing the best agreement for values & lt;10 mmHg. There was also a trend for decreased concordance between eRAP IVC , eRAP E / e ′ , eRAP HV , and iRAP across the 5- to 20-mmHg categories, and iRAP was significantly different from eRAP E / e ′ and eRAP HV for the 20-mmHg category (Wilcoxon signed-rank test P = 0.02 and P & lt; 0.001, respectively). The areas under the curve in predicting iRAP were nonsignificantly better for eRAP mean than for eRAP IVC at both 5-mmHg [0.64, 95% confidence interval (CI) 0.49–0.80 vs. 0.70, 95% CI 0.53–0.87; Wald test P = 0.41] and 10-mmHg (0.76, 95% CI 0.60–0.92 vs. 0.81, 95% CI 0.67–0.96; P = 0.43) thresholds. Conclusions: Our data suggest that multiparametric eRAP mean does not provide advantage over eRAP IVC , despite being more complex and time-consuming.
