Transvenous lead extraction (TLE) of the Starfix coronary sinus (CS) active-fixation lead may be challenging, due to undeployment of fixation lobes and venous occlusion. We report our experience in Starfix TLE, in comparison with previous data. A 78-year-old male, implanted in 2009 with Starfix lead, was referred to our institution for TLE, due to infective endocarditis with lead-associated vegetations. The tip of Starfix lead was located in distant, anterior position, in the great cardiac vein, close to patent left internal mammary artery-to-left anterior descending artery anastomosis, and first-choice surgical removal had a prohibitive operative risk. Conventional dilatation beyond CS ostium, as well as the use of a standard delivery catheter, was ineffective. An off-label modification of the delivery, by cutting the distal soft tip, was successful. However, the tip of the lead fragmented and was trapped in the innominate vein. Then a gooseneck snare grasped the fragment, allowing complete retrieval. TLE of Starfix leads may be particularly challenging, especially when its tip is located in a distant anterior location. In these cases, important help may be obtained by dilatation within the CS, by means of conventional or modified delivery catheters. Only experienced operators, sometimes with non-conventional techniques, should perform TLE of Starfix leads. < TLE of Starfix leads may be challenging, particularly when the tip is located in a distant anterior position. Dilatation with conventional tools may be precluded. In these cases modifications of the delivery catheters may be useful. Surgery should be avoided as first-choice procedure; only experienced operators, sometimes with non-conventional techniques, should perform TLE of Starfix leads.>.
由于固定叶未展开和静脉闭塞,Starfix冠状静脉窦(CS)主动固定导线的经静脉导线拔除术(TLE)可能具有挑战性。我们报告了我们在Starfix TLE方面的经验,并与之前的数据进行比较。一名78岁男性于2009年植入Starfix导线,因感染性心内膜炎伴导线相关赘生物被转诊至我院进行TLE。Starfix导线尖端位于心脏大静脉的远处、前方位置,靠近左乳内动脉至左前降支动脉的吻合口,首选手术切除的手术风险过高。超出CS口的传统扩张以及使用标准输送导管均无效。通过切割远端软尖端对输送方式进行非标签修改取得了成功。然而,导线尖端断裂并被困在无名静脉中。然后用鹅颈圈套器抓住碎片,实现了完全取出。Starfix导线的TLE可能特别具有挑战性,尤其是当其尖端位于远处前方位置时。在这些情况下,通过使用传统或改良的输送导管在CS内进行扩张可能会获得重要帮助。只有经验丰富的操作人员,有时采用非常规技术,才能进行Starfix导线的TLE。<Starfix导线的TLE可能具有挑战性,特别是当尖端位于远处前方位置时。可能无法使用传统工具进行扩张。在这些情况下,对输送导管进行修改可能会有用。应避免将手术作为首选程序;只有经验丰富的操作人员,有时采用非常规技术,才能进行Starfix导线的TLE。>
