Evaluation of an individual requiring permanent cardiac pacing and implantable cardioverter defibrillator (ICD) function revealed no suitable thoracic vascular access for traditional device implantation. Because the patient refused cardiac surgery, a left femoral venous approach was used to introduce two extended-length, active fixation leads that were positioned in the right atrium and ventricle. The leads were tunneled to the abdomen and connected to a dual-chamber ICD. A low defibrillation threshold and robust pacing and sensing parameters were observed at implant. All of these parameters were stable at 6-month follow-up. In addition, no negative effects of the predominantly abdominal shock vector were observed. This case suggests that femoral ICD placement should be considered before routinely referring such patients for open chest surgery.
对一名需要永久性心脏起搏和植入式心律转复除颤器(ICD)功能的患者进行评估时发现,没有适合传统设备植入的胸段血管通路。由于患者拒绝心脏手术,因此采用左股静脉入路引入两根延长长度的主动固定电极导线,分别置于右心房和右心室。导线经皮下隧道引至腹部并连接到双腔ICD。植入时观察到低除颤阈值以及稳健的起搏和感知参数。所有这些参数在6个月随访时均保持稳定。此外,未观察到主要为腹部的电击向量带来的负面影响。该病例表明,在常规将此类患者转诊至开胸手术之前,应考虑经股静脉植入ICD。
