We report the identification by multiplane transesophageal echocardiography of a vegetation on a permanent pacemaker lead in a patient with persistent bacteriemia. The lesion could not be visualized with transthoracic echocardiography. The diagnosis of vegetation was based on the visualization of a freely highly mobile mass attached to the pacemaker lead, with different echogenicity from the lead. The entire pacing system was surgically removed through a right atrial approach, and inspection confirmed pacemaker lead vegetation. We conclude that transesophageal echocardiography should be considered to investigate suspected pacemaker lead infection in patients with negative transthoracic echocardiography.
我们报告了1例持续性菌血症患者,通过多平面经食管超声心动图识别出其永久性起搏器导线上有赘生物。经胸超声心动图无法显示该病变。赘生物的诊断基于可视化观察到一个高度活动的、附着于起搏器导线上的游离团块,其回声与导线不同。通过右心房入路手术切除了整个起搏系统,检查证实为起搏器导线赘生物。我们得出结论,对于经胸超声心动图检查结果为阴性的疑似起搏器导线感染患者,应考虑行经食管超声心动图检查。
