ABSTRACT
Objective To explore the value of tricuspid annular displacement (TAD) in evaluating right ventricular systolic function by speckle tracking imaging.Methods Forty healthy people (RVEF >50%) and forty five patients(RVEF <50%)were enrolled in this study.The apical four-chamber view was obtained and tricuspid annular midpoint displacement (TADmid) were measured by speckle tracking imaging.Right ventricular ejection fraction (RVEF) was measured by three-dimensional echocardiography.The correlation of tricuspid annular midpoint displacement (TADmid) and right ventricular ejection fraction (RVEF) was analyzed.Results These was statistical significance of tricuspid annular midpoint displacement between healthy people (RVEF > 50%) and patients (RVEF < 50%) (t = 7.28,P < 0.01).There was positive correlation between TADmid and RVEF (P < 0.01).The correlation coefficient between TADmid and RVEF was 0.76 (P < 0.0l).The cut-off value of TADmid for RVEF > 50% was 9.7 with a sensitivity of 72% and a specificity of 86%.Conclusions TAD by speckle tracking imaging showed an excellent correlation with RVEF.Tricuspid annular displacement by speckle tracking imaging was a simple and easy method,and it might be a new index in assessing right ventricular systolic function in clinical practice.
