| 摘要: |
| 目的 初步探讨经食道超声心动图（TEE）应用于左心耳封堵术预防心房颤动患者脑栓塞的临床意义。方法 3例房颤患者（CHA2DS2VAS评分均≥2分）行左心耳封堵术，术前应用TEE观察左心耳形态、功能，测量左心耳（LAA）最大入口径及深度，术中TEE引导房间隔穿刺，鞘管定位及封堵器的释放，术后评价效果，术后45天左右运用TEE随访，观察疗效。结果 3例患者均封堵成功，均选择型号为27mm的Watchman封堵器，1例可见4mm残余分流。术后随访无并发症，结论 TEE在左心耳封堵术的术前、术中、术后发挥着重要的应用价值，为房颤患者预防脑栓塞提供技术支持。 |

| Abstract: |
| Objective To investigate the clinical value of left atrial appendage (LAA) occlusion through transesophageal echocardiography (TEE) guiding in preventing patients with atrial fibrillation from cerebral embolism．Methods 3cases of patients with atrial fibrillation for left atrial appendage occlusion, CHA2DS2VAS score was 2 points or higher. Measured the largest diameter and depth of LAA,Form and function of LAA were observed by TEE before operation.TEE guided interatrial septum piercing, sheath pipe positioning and the release of the closure were implemented in the operation . After the operation,we evaluation effect and follow-up about 45 days by the TEE.Results 3 cases patient of atrial fibrillation successfully completed left atrial appendage occlusion.We used 27 mm diameter Watchman.1 case with 4mm residual shunt,no complication in postoperative follow-up．Conclusions TEE has the important application value in left atrial appendage occlusion between preoperative,intraoperative and postoperatively.It provides technical support for the prevention of cerebral embolism in patients with atrial fibrillation. |
