目的探讨实时经食管超声心动图(TEE)在左心耳封堵术中的应用。方法术前应用经胸超声心动图(TTE)及TEE检查结合病史筛选手术适应证患者13例,评价左心耳形态、测量左心耳内径及深度,术中TEE联合造影结果选择封堵器型号,引导房间隔穿刺、封堵器植入或回收再释放过程,术后即刻评价封堵疗效、有无并发症并随访。结果 13例患者均成功完成左心耳封堵,未出现封堵相关并发症。术后TEE及TTE随访显示封堵器形态位置良好,手术前后患者超声心动图左心室射血分数无明显改变,患者均未出现封堵器相关不良事件。结论左心耳封堵术应用TEE可获得较高的成功率和较低的并发症发生率,具有重要应用价值。
Objective To investigate the application of real-time transesophageal echocardiography (TEE) in the occlusion of the left atrial appendage. Methods Thirteen patients with surgical indications were screened by transthoracic echocardiography (TTE) and TEE examination combined with medical history. The shape of left atrial appendage was evaluated, the diameter and depth of left atrial appendage were measured, and the occluder type and guidance Atrial septal puncture, occluder implantation or re-release process of release, assessment of closure immediately after the curative effect, with or without complications and follow-up. Results All the 13 patients successfully completed the occlusion of the left atrial appendage and no occlusion related complications occurred. Follow-up of TEE and TTE showed that occluder morphology was good, and left ventricular ejection fraction did not change significantly before and after echocardiography. No occluder-related adverse events occurred in all patients. Conclusion The application of TEE in the left atrial appendage closure has a high success rate and a low incidence of complications, which is of great value.
