Permanent transvenous cardioverter-defibrillator leads were investigated by multiplane transesophageal echocardiography (TEE) (1) to determine whether intracardiac lead segments can be visualized, (2) to verify the position of the coils, and (3) to detect possible thrombus formation. The diagnostic information obtained in 62 patients by TEE was compared to that of transthoracic echocardiography (TTE). Abnormal findings were only visualized by multiplane TEE. However, further controlled studies are needed to determine the clinical relevance of displaced caval (one patient) and ventricular coils (15 patients), ventricular (1 patient) or atrial (6 patients) loops, and of clinically uneventful thrombi (13 patients).
采用多平面经食管超声心动图（TEE）对永久性经静脉心脏复律除颤器导线进行研究，目的如下：（1）确定心内导线节段是否可视；（2）核实线圈位置；（3）检测可能形成的血栓。将62例患者经TEE获得的诊断信息与经胸超声心动图（TTE）的诊断信息进行比较。异常发现仅通过多平面TEE显示。然而，需要进一步的对照研究来确定腔静脉移位（1例患者）和心室线圈移位（15例患者）、心室（1例患者）或心房（6例患者）袢以及临床上无明显症状的血栓（13例患者）的临床相关性。
