The implantable cardioverter defibrillator (ICD) is a life-saving therapy in various patient populations. Although data on the outcomes of initial ICD implants are abundant, data on ICD replacements, especially in patients with improved left ventricular (LV) function, are scarce. Therefore, it is not known when it is safe to not replace an ICD that has reached the end of battery life. This article reviews data on patients with primary prevention ICDs who have improvement in left ventricular ejection fraction during follow-up and provides some guidance, based on the available evidence, related to circumstances when replacement of an ICD may be forgone.
植入式心脏复律除颤器（ICD）对各类患者群体而言都是一种挽救生命的治疗手段。尽管关于初次植入ICD的结果数据丰富，但关于ICD更换的数据，尤其是左心室（LV）功能改善患者的数据却很稀少。因此，尚不清楚对于已达到电池寿命终点的ICD，何时不进行更换是安全的。本文回顾了一级预防ICD患者在随访期间左心室射血分数有所改善的数据，并根据现有证据，针对在何种情况下可以放弃更换ICD提供了一些指导。
