- Abstract
Background 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/m2 and 19.05 ± 6.87 mL/m2, 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.
