Key Lessons from the ELECTRa Registry in the Modern Era of Transvenous Lead Extraction

摘要

The implantation rate of cardiac electronic devices has grown over the past decades. The number of treated patients has increased in parallel with the complexity of the patient population treated, being older, frailer, having more complex devices (in particular, cardiac resynchronisation therapy) and presenting with a greater comorbidity burden. As a consequence, there is a rising number of related implanted system complications, including malfunction and infection. Thus, the demand for transvenous lead extraction (TLE) has also substantially increased. To identify the indication to TLE by various operators and centres, techniques used to perform TLE, and the safety and efficacy of the current clinical practice of TLE, a large prospective registry has been started in Europe – the European Lead Extraction Controlled (ELECTRa) Registry. The key findings of the ELECTRa Registry are discussed in the present review and placed in the context of previous knowledge. The ELECTRa Registry confirms that the TLE procedure is a safe and effective treatment, with an acceptable risk–benefit ratio that is comparable with other well-known cardiological invasive procedures. Of course, TLE is accompanied by potential life-threatening complications; the vast majority of these can be managed by an experienced multidisciplinary team. Multiple factors predict complications, including patient/lead profile, centre experience and procedure volumes, which may suggest caution when accepting a patient for TLE.
