A reservoir (Mediport) catheter in the superior vena cava and right atrium can present as a right atrium mass lesion by echocardiography. Unlike pacemaker or transvenous catheters, these are not easily detected because the implant sites are not obvious and they are not attached to external intravenous device. Transvenous reservoír catheters should be considered in the echocardiographic diagnosis of right atrial mass lesion.
上腔静脉和右心房中的贮液器（Mediport）导管通过超声心动图检查可表现为右心房肿块病变。与起搏器或经静脉导管不同，这些导管不易被检测到，因为植入部位不明显，且它们未连接到外部静脉装置。在右心房肿块病变的超声心动图诊断中应考虑经静脉贮液器导管。
