Abstract:
Objective:To explore the morphological parameters of tricuspid in patients with moderate or above functional tricuspid regurgitation (FTR ) by real-time three-dimensional (3D) transthoracic echocardiography.Methods:A total of 31 moderate or above FTR(FTR group) and 36 healthy adults(control group) were included in the study from May to July 2020 in the First Affiliated Hospital of Air Force Medical University (Xijing Hospital). Two-dimensional (2D) and 3D echoardiography were performed on both FTR group and control group. The 2D parameters included tricuspid regurgitation (TR), transverse diameter of right atrium/ ventricle, transverse diameter of tricuspid annulus(TVD), left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS). The tricuspid 3D parameters were analyzed by TomTec software, including annular parameters[annular anterior-posterior diameter (AP), annular left-right diameter (AL-PM), sphericity index (SI=AP/AL-PM), non-planar angle (NPA), annulus circumference (AC), annulus area (AA), annulus height (AH)], leaflet parameters[tenting volume(TV), tenting area(TA), tenting heigh(TH), commissural diameter(CD)], and dynamic parameters[annular displacement max(ADmax), annulus area fraction(AAF)].Results:Compared with the control group, AP, AL-PM, SI, AC, AA, TV, TA parameters of FTR group were larger, ADmax was smaller (all P<0.05). Multiple linear regression model was used to evaluate the effects of RA, RV, AP, AL-PM, SI, TV, TA on FTR, and the results showed that FTR was associated with TV and TA( t=4.253, -2.14; all P<0.05). Conclusions:RT-3DE can be used to assess the morphological parameters of tricuspid valve with moderate or above FTR patients effectively. TV and TA are the two most important factors for moderate or above FTR.
