An 18-year-old woman underwent the repair of traumatic lacerations of the mitral valve, tricuspid valve, and interventricular septum. At the time of surgery, an indwelling left atrial catheter was placed for postoperative hemodynamic manangement. An attempt to remove the catheter completely several days following surgery was unsuccessful, but it was initially assumed by the surgeon that the tip of the catheter had been withdrawn from the left atrium. When the patient developed neurologic signs suggesting a cerebral embolism, an echocardiogram was performed. Echo demonstration of the catheter in the left atrium led to repeat thoracotomy for removal of the retained line. Baseline echocardiograms are indicated in cardiac surgical patients with indwelling left atrial catheters and echo study can be diagnostic if catheter retention occurs.
一名18岁女性接受了二尖瓣、三尖瓣和室间隔创伤性撕裂伤的修复手术。手术时，放置了一根左心房留置导管用于术后血流动力学管理。术后几天试图完全拔除导管未成功，但外科医生最初认为导管尖端已从左心房拔出。当患者出现提示脑栓塞的神经系统体征时，进行了超声心动图检查。超声心动图显示导管在左心房内，导致再次开胸取出残留导管。对于留置左心房导管的心脏手术患者，应进行基线超声心动图检查，若发生导管留置，超声心动图检查可用于诊断。
