中文摘要:
      目的 探讨实时三维经食管超声心动图(RT-3D-TEE)在经皮左心耳封堵术(PLAATO)治疗非瓣膜病性心房颤动中的应用价值。方法 对62例接受PLAATO的非瓣膜病性心房颤动患者行二维经食管超声心动图(2D-TEE)、RT-3D-TEE和心血管造影(CAG)检查,分别测量左心耳口最大径、左心耳口最小径、左心耳口深度,并比较三者的差异。以RT-3D-TEE测量的左心耳口最大径测量值为依据,选择适当封堵器型号,并在RT-3D-TEE、CAG引导下进行左心耳封堵术。术后进行随访。结果 62例均封堵成功,成功率为100%,封堵压缩率为(19.78±6.92)%;术中、术后随访期内均未发生严重并发症。2D-TEE、RT-3D-TEE及CAG测量的左心耳口最大径总体差异有统计学意义(P=0.029),RT-3D-TEE测值高于2D-TEE而低于CAG;三者测量的左心耳口最小径和左心耳深度总体差异均无统计学意义(P均>0.05)。CAG、RT-3D-TEE和2D-TEE测量的左心耳口最大径与封堵器尺寸均呈正相关(r=0.925、0.841、0.716,P均≤ 0.001)。结论 RT-3D-TEE可用于PLAATO治疗非瓣膜病性心房颤动术前筛选、术中引导和术后随访,能准确观察左心耳口形态并评估封堵效果。
英文摘要:
      Objective To investigate the value of real-time three-dimensional transesophageal echocardiography (RT-3D-TEE) in percutaneous left atrial appendage (LAA) transcatheter occlusion (PLAATO) in patients with non-valvular atrial fibrillation. Methods Totally 62 patients with non-valvular atrial fibrillation who underwent PLAATO were examined with two-dimensional transesophageal echocardiography (2D-TEE), RT-3D-TEE and cardioangiography (CAG). The maximum diameter, minimum diameter and depth of LAA were measured and compared respectively. According to the maximum diameter of LAA measured with RT-3D-TEE, occluder with appropriate type was selected, and LAA occlusion was performed under the guidance of RT-3D-TEE and CAG. Follow-up was conducted after operation. Results Occlusion was successfully performed in all 62 patients, the success rate was 100%, and the compression rate was (19.78±6.92)%. No serious complications occurred during the operation and follow-up period. There was significant difference of the maximum diameter of LAA measured with 2D-TEE, RT-3D-TEE and CAG (P=0.029). The maximum diameter of LAA measured with RT-3D-TEE was higher than that measured with 2D-TEE, while lower than that measured with CAG. There was no significant difference of the minimum diameter nor depth of LAA measured with 2D-TEE, RT-3D-TEE and CAG (both P>0.05). The maximum diameter of LAA measured with CAG (r=0.925), RT-3D-TEE (r=0.841) and 2D-TEE (r=0.716) were positively correlated with the size of occluder (all P ≤ 0.001). Conclusion RT-3D-TEE can be used for preoperative screening, intraoperative guidance and post-operative follow-up of PLAATO for non-valvular atrial fibrillation, which may accurately describe the shape of LAA and evaluate the effect of occlusion.
