Lead-related infective endocarditis is a serious complication of implantable cardioverter-defibrillators (ICDs), especially in patients with advanced heart failure who are poor surgical candidates. Management of large lead-associated vegetations remains a clinical challenge.
We present the case of a 54-year-old woman with ischemic cardiomyopathy and recurrent ICD complications who developed bacteremia and infective endocarditis with vegetations on the aortic valve and a 1.5 × 1.3 cm mass on the right ventricular lead. Given her poor surgical candidacy due to worsening heart failure, a percutaneous approach was pursued.
The patient underwent successful intracardiac echocardiography (ICE)-guided catheter-based vegetation removal using a vacuum-assisted aspiration system, followed by transvenous lead extraction. The procedure was well tolerated, and the patient demonstrated clinical improvement post intervention.
This case illustrates the utility of ICE-guided percutaneous aspiration and lead extraction for managing large lead-related vegetations in patients with infective endocarditis who are not candidates for surgery.
铅相关感染性心内膜炎是植入式心脏复律除颤器(ICD)的严重并发症,尤其在晚期心力衰竭且手术风险高的患者中。处理与导线相关的大型赘生物仍是一项临床挑战。
我们报告了一名54岁患有缺血性心肌病且ICD反复出现并发症的女性病例,她发生了菌血症和感染性心内膜炎,主动脉瓣上有赘生物,右心室导线上有一个1.5×1.3厘米的肿物。鉴于其因心力衰竭恶化而手术风险高,故采用经皮方法。
患者在心脏内超声(ICE)引导下,使用真空辅助抽吸系统成功进行了基于导管的赘生物清除,随后进行了经静脉导线拔除。该操作耐受性良好,患者术后临床症状改善。
本病例说明了ICE引导下经皮抽吸和导线拔除在处理感染性心内膜炎且不适合手术的患者中与导线相关的大型赘生物的实用性。
