Kurzfassung:
Current guidelines do not recommend routine assessment of right atrial volume due to the lack of standardized data. Three‐dimensional wall‐motion tracking (3 D ‐ WMT ) is a new technology that allows us to calculate volumes without any geometric assumptions. The aim of this study was to define the indexed reference values for two‐dimensional echocardiography (2 D ‐echo) and 3 D ‐ WMT in adult healthy population and to assess the intermethod, intra‐ and interobserver agreement. Methods Prospective study. Nonselected healthy subjects were enrolled. Every patient underwent a 2 D ‐echo and a 3 D ‐ WMT examination. 2 D ‐echo right atrial volume was obtained by using the area‐length method ( A ‐ L ) from four‐ and two‐chamber view. 3 D ‐echo volumes were assessed by 3 D ‐ WMT . Values were indexed by the patient's body surface area. Results Sixty consecutive healthy subjects were enrolled. Mean age was 57 ± 12‐years old and 27 patients (45%) were male. Average indexed right atrial volume obtained by 2 D ‐echo and 3 D ‐echo was 16.76 ± 8.15 mL/m 2 and 19.05 ± 6.87 mL/m 2 , respectively. Univariate linear regression analysis between 2 D ‐echo and 3 D ‐echo right atrial volumes shows a weak correlation between right atrial volume obtained with 2 D ‐echo compared with 3 D ‐ WMT (r = 0.29, CI 95% 0.029–0.66, P = 0.033). The agreement analysis shows a similar result (intraclass correlation coefficient [ ICC ] = 0.28). The intra‐ and interobserver agreement analysis showed a better agreement when using 3 D ‐ WMT . Conclusions This is the first study that reports the reference indexed right atrial volume values by means of 2 D ‐echo and 3 D ‐echo in healthy population. 3 D ‐ WMT is a feasible and reproducible method to determine right atrial volume.
