Abstract

Background: Severe tricuspid regurgitation (TR) is associated with high mortality rate. Tricuspid valve imaging is often challenging and requires the use of multiple modalities.


Understanding discrepancies and agreement among different imaging techniques is crucial for planning transcatheter valve interventions.


Aims: Comparison between two-dimensional transthoracic echocardiography, three-dimensional transthoracic/ transesophageal echocardiography and computed tomography for comprehensive tricuspid annulus (TA) assessment in severe TR patients.


Patients and Methods: From 08/2019 to 09/2020, forty patients with severe TR were included in this study. TA measurements were made at end diastole using two-dimensional (2D) transthoracic echocardiography (TTE), three-dimensional (3D) TTE direct planimetry and transesophageal echocardiographic (TEE) direct planimetry. Both methods were compared with multi-detector computed tomographic (MDCT) planimetry.


Results: TA diameters measured with 2D TTE were smaller compared with direct MDCT measurements (40.5 ± 7.2 mm vs 43.3 ± 13.5 mm, p<0.05 on 4-chamber view, và 32.6 ± 7.4mm vs 38.0 ± 12.4mm, p<0.05 on short-axis view). There was no significant difference between TA diameters measured with 3D TTE/ 3D TEE and MDCT measurements (42,8 ± 7,1 mm / 43,6 ± 7,4mm vs 43,3 ± 13,5 mm, p>0,05 on 4-chamber view and 35,7 ± 6,1 mm /39,1 ± 7,6 mm vs 38,0 ± 12,4 mm, p > 0,05 on short-axis view). TA circumferences on 3D TTE and 3D TEE strongly correlated to TA circumference on MDCT (r=0,62, p<0,05 và r=0,54, p<0,05, respectively).  TA areas on 3D TTE and 3D TEE very strongly correlated to TA area on MDCT (r = 0,87, p < 0,05 và r = 0,89, p < 0,05, respectively).  


Conclusions: Tricuspid annular size measured with 3D TTE and 3D TEE strongly correlated to tricuspid annular measurements on MDCT.
