Abstract:
The aim of this study was to assess the accuracy and reproducibility of real time three‐dimensional echocardiographic ( RT 3 DE ) for the determination of right ventricular ( RV ) volumes and function in patients with left ventricular (LV) systolic dysfunction. Methods and Results Dedicated RT 3 DE was prospectively performed to assess RV volumes and EF in patients with LV systolic function identified on routine clinical cardiac magnetic resonance ( CMR ) imaging. RV end‐diastolic volume ( RV EDV ), RV end‐systolic volume ( RV ESV ), and RV EF were obtained using an offline analysis software (TomTec) by two observers blinded to CMR results. In this population of 27 patients with LV systolic dysfunction with a mean LV EF of 36 ± 12%, RV RT 3 DE dataset could be assessed in 27 of 30 patients (90%). High correlation was noted between RT 3 DE and CMR for RV EDV , ESV , and EF (r = 0.90, 0.89, and 0.77, respectively). RV EDV was lower by RT 3 DE as compared to CMR (129 ± 52 vs. 142 ± 53 mL, P = 0.005) while there was no significant difference in RV ESV and RV EF (71 ± 37 vs. 77 ± 45 mL, P = 0.146; 45 ± 11 vs. 48 ± 13%, P = 0.134, respectively). The intraclass correlation coefficient ranged from 0.94 to 0.94 between measurements and from 0.84 to 0.96 between observers. Conclusion Overall, RV volumes and EF assessed by RT 3 DE correlate well with CMR measurements in patients with LV dysfunction. RT 3 DE may be used as a more widely available and versatile alternative to CMR for the quantitative assessment of RV size and function in patients with LV dysfunction.
