The aims of this study are to evaluate whether TDE\u2010Tei index also exerts a correlation with left ventricular (LV) systolic and diastolic function and filling pressure and to see whether it can effectively identify the pseudonormal\/restrictive mitral filling pattern. Methods: Echocardiographic examination was performed in 243 consecutive patients. These patients were classified into three groups as normal, abnormal relaxation, and pseudonormal\/restrictive groups according to the transmitral E\/A\u2010wave velocity (E\/A), early diastolic velocity of lateral mitral annulus (Ea) and E\/Ea. Results: Standard Doppler indices of LV filling such as E, A, E\/A, and E\u2010wave deceleration time had a bimodal distribution, but Ea decreased and E\/Ea and TDE\u2010Tei index increased progressively with worsening of LV diastolic function. The sensitivity and specificity of TDE\u2010Tei index &gt;0.51 in the discrimination of pseudonormal\/restrictive filling pattern were 85% and 96%, respectively. After stepwise multiple linear regression analysis, TDE\u2010Tei index had a significant negative correlation with Ea (\u03b2=\u22120.296, P &lt; 0.001) and ejection fraction (\u03b2=\u22120.293, P &lt; 0.001) and positive correlation with E\/Ea (\u03b2= 0.235, P = 0.001). Conclusions: TDE\u2010Tei index increased with worsening of LV diastolic function and can effectively identify the pseudonormal\/restrictive mitral inflow pattern. It also correlated with the echocardiographic parameters of LV systolic and diastolic function and filling pressure. It suggests that TDE\u2010Tei index is a simple and feasible marker in assessing global LV function.<\/jats:italic>
