    Recently, the Sherlock 3CG™ Tip Confirmation System, including a magnetic tracking system and an intracavitary electrocardiography guidance system, has been introduced for bedside peripherally inserted central catheter (PICC) insertion. Magnetic field sources interfere with the magnetic tracking system. Electromagnetic interference of the ventricular assist device (VAD) has already been reported with various devices but not on Sherlock 3CG™. We assessed the availability of the magnetic tracking system in patients with and without a VAD during Sherlock 3CG™ insertion and evaluated the rate of optimal PICC tip position. We retrospectively reviewed 99 patients who had undergone PICC insertion using Sherlock 3CG™ on the bedside at our institutional intensive care unit from February 2018 to December 2020. Patients were divided into groups with and without a VAD. The availability of magnetic navigation and the success rate of optimal catheter tip position in each group were assessed. Among 87 cases analyzed, there were 12 and 75 cases with a VAD and without a VAD, respectively. The availability of magnetic navigation during Sherlock 3CG™ insertion was significantly lower in the group with a VAD [4/12 (33%) with VAD vs. 72/75 (96%) without VAD, P < 0.001]. In addition, the rate of optimal PICC tip position was also significantly lower in the group with a VAD [6/12 (50%) vs. 63/75 (84%), P = 0.015] The VAD significantly led to magnetic tracking system failure due to its electromagnetic interference during Sherlock 3CG™ insertion and significantly reduced the success rate of PICC insertions in the optimal position.

    <p> In this report, we describe the case of a patient with a massive primary cardiac malignant lymphoma who underwent anesthetic management for transvenous pacemaker implantation, which was safely performed using combined transesophageal echocardiography (TEE) and fluoroscopy intraoperatively with pacing lead placement guided by echocardiography.</p><p> A 71 year-old male was diagnosed with a massive cardiac malignant lymphoma. The tumor occupied the right atrium and ventricle, as well as the vena cava. Electrocardiography revealed a complete atrioventricular block. Elective pacemaker implantation under general anesthesia was planned. General anesthesia was carefully introduced with extracorporeal circulation on stand-by in case of collapsed circulation.</p><p> Intraoperatively, guiding the pacing lead to the proper position was difficult for the cardiovascular surgeon. The anesthesiologist then suggested the use of TEE for guiding the pacing lead. Subsequently, the pacing lead was successfully placed in the appropriate position by a combination of TEE guidance and fluoroscopy without any cardiovascular complications.</p><p> TEE guidance may be considered feasible and efficient for transvenous pacemaker implantation under general anesthesia.</p>
