摘　　要：非瓣膜性心房颤动因其高发病率、高致残率和高复发率,严重影响了患者的生活质量。准确评估左心耳的结构和功能,对检测左心耳血栓和预测卒中事件至关重要。以经食管超声心动图、经胸超声心动图、心腔内超声心动图、CT和心脏磁共振成像等为主的传统影像学技术,和以新型分子靶向示踪剂结合的正电子发射断层扫描/心脏磁共振成像、计算机流体力学等为代表的新兴技术,正为左心耳的结构功能评估以及左心耳血栓的检测提供着重要客观依据。本文对非瓣膜性心房颤动患者左心耳的解剖、功能、左心耳及其血栓的影像学研究进展进行综述。Non-valvular atrial fibrillation has seriously affected the quality of life of patients because of its high incidence,high disability rate and high recurrence rate.Accurate evaluation of the structure and function of left atrial appendage is of great importance in detection of its thrombus and in prediction for stroke events.Conventional imaging techniques,such as transesophageal echocardiography,transthoracic echocardiography,intracardiac echocardiography,CT and cardiac magnetic resonance imaging,and new technologies,represented by positron emission tomography/cardiac magnetic resonance imaging combined with new molecular targeted tracers,and computer fluid dynamics,are providing important objective basis for evaluating its structure and function and for detecting its thrombus.In this article,we reviewed the anatomy,function,imaging progress of left atrial appendage and its thrombus in patients with non-valvular atrial fibrillation.
