Description
Summary:Abstract Background Data on the use of wearable cardioverter defibrillator (WCD) among patients after cardiac implantable electronic device explantation of 1- to 3-chamber Implantable Cardioverter-defibrillator system (ICD) are sparse. Subsequently several guidelines give a different recommendation regarding WCD indication in this cohort. Objectives We aimed to study the baseline characteristics and outcome of patients treated with WCD after ICD explantation. The primary outcome is appropriate WCD shock. Methods 1104 patients were included in a multicenter registry from seven European centers. Among this cohort 109 patients received a WCD to bridge the time after ICD-system explantation until reimplantation due to a persistent ICD-indication. The mean follow-up time of the whole cohort was 824±773 days. Cardiovascular history and non-cardiovascular morbidities were evaluated. In addition, the presence of ventricular tachyarrhythmias and/or WCD shocks was evaluated in the explantation group. Furthermore, after ICD-reimplantation the rate of rehospitalization for ventricular tachyarrhythmias, atrial fibrillation, stroke and congestive heart failure was followed. Results In the explantation group patients were older (65±14 versus 59±15; p
