摘　　要：斑点追踪技术(STI)能够追踪心肌的运动轨迹,且价格便宜、无辐射、可重复性高,能够在主动脉瓣狭窄(AS)病程早期检测出心肌应变能力的下降,从而指导临床作出治疗决策。本文就STI在AS患者左心室功能评估、手术疗效评价、术后并发症预测和预后评估的应用进行综述。Speckle-tracking imaging(STI)is an inexpensive,radiation-free,repeatable technique,and can track the movement track of myocardium.It can detect the decline in myocardial strain capacity at the early stage of aortic stenosis,and guides clinical treatment decisions.This article reviews the application of STI in the evaluation of left ventricular function and surgical efficacy and in the prediction of postoperative complications and prognosis in patients with aortic stenosis.
