左心房在心动周期中发挥储蓄、管道和辅泵功能,对左心室的舒张功能和维持正常心搏量起重要作用。左心房功能受左心室收缩和舒张功能的影响,是心血管事件发生的独立预测因子。左心房容积增大和功能降低是心房颤动、心力衰竭、栓塞、死亡等心血管高危因素的重要预测指标。实时三维超声心动图能早期准确评价左心房功能,对心血管疾病选择治疗方法、评价治疗效果及预后评估有重要作用。本文就实时三维超声心动图临床评估左心房功能指标的研究进展作一综述。
Left atrium in the cardiac cycle to play a saving, pipeline and auxiliary pump function, the left ventricular diastolic function and maintain normal stroke volume plays an important role. Left atrial function is influenced by left ventricular systolic and diastolic function and is an independent predictor of cardiovascular events. Left atrial volume increase and decreased function is an important predictor of cardiovascular risk factors such as atrial fibrillation, heart failure, embolism, and death. Real-time three-dimensional echocardiography early accurate assessment of left atrial function, the choice of treatment for cardiovascular disease, evaluation of the treatment effect and prognosis evaluation plays an important role. This review summarizes the progress of real-time three-dimensional echocardiography in clinical assessment of left atrial function.
