摘要(Abstract)：

<正>心血管超声技术在心脏介入诊疗中起到非常重要的作用。传统的超声心动图包括经胸超声心动图(transthoracic echocardiography, TTE)和经食管超声心动图(transesophageal echocardiography, TEE)。TTE是临床工作中最常用的方法,但是容易受到含气的肺组织等其他心脏周围结构的影响,故TTE不能清晰显示远离探头的心房结构和近端心尖部结构。TEE可从食管显示心腔结构,特别是左心耳和瓣膜结构,但是仍有部分患者不能耐受TEE检查,以及存在麻醉和潜在的食管损伤/穿孔的风险。心内超声(intracardiac echocardiography,ICE)是将超声探头经外周静脉入径送至心腔内,由于ICE探头周围为心腔内血液,故能提供更加清晰的图像质量,且不受心
