Recent studies have explored the prognostic role of TDI-derived parameters in major cardiac diseases, such as coronary artery disease (CAD) and heart failure (HF). In these conditions, myocardial mitral annular systolic (S') and early diastolic (E') velocities have been shown to predict mortality or cardiovascular events. In heart failure non invasive assessment of LV diastolic pressure by transmitral to mitral annular early diastolic velocity ratio (E/E') is a strong prognosticator, especially when E/E' is > or =15. Moreover, other parameters derived by TDI, as cardiac time intervals and Myocardial Performance Index, might play a role in the prognostic stratification in CAD and HF. Recently, a three-dimensional (3-D) TDI imaging modality, triplane TDI, has become available, and this allows calculation of 3-Dvolumes and LV ejection fraction. We present a brief update of TDI.
最近的研究探讨了组织多普勒成像（TDI）衍生参数在主要心脏疾病中的预后作用，如冠状动脉疾病（CAD）和心力衰竭（HF）。在这些情况下，心肌二尖瓣环收缩期（S'）和舒张早期（E'）速度已被证明可预测死亡率或心血管事件。在心力衰竭中，通过二尖瓣跨瓣舒张早期速度与二尖瓣环舒张早期速度比值（E/E'）对左心室舒张压进行无创评估是一个强有力的预后指标，尤其是当E/E'≥15时。此外，TDI衍生的其他参数，如心脏时间间期和心肌性能指数，可能在CAD和HF的预后分层中发挥作用。最近，一种三维（3-D）TDI成像模式，即三平面TDI已经可用，这使得能够计算三维容积和左心室射血分数。我们简要介绍一下TDI的最新情况。
