[Abstract]:Objective: to investigate the systolic displacement of tricuspid annulus and the Tei index measured by conventional echocardiography. The correlation between right ventricular ejection fraction (RVEF) and right ventricular ejection fraction (RVEF) in patients with severe tricuspid regurgitation (TRT) and the clinical application value of tricuspid annular systolic peak velocities (RV) and real-time three-dimensional echocardiography (RT-3DED) in the evaluation of right ventricular function in patients with severe tricuspid regurgitation (TRV). Data and methods:. From February 2016 to February 2017, 18 patients with severe tr in our hospital were selected as study subjects. There were 7 males and 11 females, aged 73.7 鹵9.7 years, with BMI of 21.1 鹵3.4 kg / m2. 20 normal adults of the same age as the severe tr group were selected as the control group, including 11 males and 9 females. Age 67.5 鹵9.3 years old, BMI 23.1 鹵3.97 kg / m2. All patients with severe tr and control group underwent routine two-dimensional echocardiography. Tissue Doppler echocardiography, M-mode echocardiography and RT-3DE were used to measure TAPSE. TDI technique was used to measure Tei index and tricuspid annulus of right ventricular free wall. RT-3DE was used to measure right ventricular end-diastolic value. The correlation between conventional echocardiography and quantitative parameters of RT-3DE was analyzed, such as RV VV, right ventricular end-systolic volume (RV VV), right ventricular ejection fraction (RVEF) and so on. The quantitative parameters of conventional echocardiography and RT-3DE were compared between the study group and the control group. Results the Tei index of tricuspid annulus and Tei index at right ventricular free wall tricuspid annulus and RT-3DE were measured under the condition of TDI in severe tr group. The RVEF was significantly correlated with RV 0.680, P0. 002 and RV-0. 531, P = 0. 023. The correlation between tricuspid annulus S 'and RVEF was the most significant. In the control group, the TAPSE measured by M-mode echocardiography and the Tei index of right ventricular free wall tricuspid annulus measured under TDI condition were the most significant. There was a significant correlation between S 'and RVEF in tricuspid annulus. The values of S 'and RVEF of tricuspid annulus decreased significantly in severe tr group. The area of tr was significantly correlated with RVEF value in severe tr group, indicating that the degree of tr increased with the severity of tr. Conclusion in the control group, TAPSE measured by M-mode echocardiography and Tei index at tricuspid annulus of right ventricular free wall and tricuspid annulus S 'and RT-3DE measured under TDI condition were also significantly decreased in patients with severe tr. Conclusion\%\%\%\%\%\%\%\%\%\%\%\%\%\%\%\%\%\%\%\%\%\%? In severe tr group, tricuspid annulus S', right ventricular free wall tricuspid annulus Tei index and RVEF measured by RT-3DE were used to evaluate the right ventricular function in patients with severe tr. There was significant correlation. 3, compared with the control group, The values of S 'and RVEF of tricuspid annulus decreased significantly in severe tr group. In severe tr group, the right ventricular function decreased more significantly with the further aggravation of tr.
