Aims: Data on outcomes in patients using the wearable cardioverter-defibrillator (WCD) > 90 days are limited. We aimed to analyse the clinical course of patients with WCD use ≤90 days vs. WCD use >90 days. Methods and results: We assessed arrhythmia events during WCD use, and ejection fraction (EF) improvement/implantable cardioverter-defibrillator (ICD) implantation at the end of WCD use in patients with WCD use ≤90 days vs. WCD use >90 days enrolled in the WEARIT-II registry, further assessed by disease aetiology (ischaemic vs...

The wearable cardioverter-defibrillator (WCD) was introduced to provide protection from sudden cardiac death (SCD) in patients with transiently elevated risk or during ongoing risk stratification. Benefits and clinical characteristics of routine WCD use remain to be assessed in larger patient populations. This study aims to identify determinants of WCD compliance, therapies, and inappropriate alarms in a real-life cohort. A total of 106 cases (68.9% male) were included between 11/2010 and 04/2016. WCD therapies, automatically recorded arrhythmia episodes, inappropriate WCD alarms, patient compliance, and outcome after WCD prescription were analyzed...

AIM: To examine whether wearable cardioverter defibrillator (WCD) alarms for asystole improve patient outcomes and survival. METHODS: All asystole episodes recorded by the WCD in 2013 were retrospectively analyzed from a database of device and medical record documentation and customer call reports. Events were classified as asystole episodes if initial presenting arrhythmia was asystole (< 10 beats/minor ≥ 5 s pause). Survival was defined as recovery at the scene or arrival to a medical facility alive, or not requiring immediate medical attention...

We report on a case of a young female suffering from both obsessive-compulsive disorder (OCD) and a severe underlying cardiac disease. Due to the somatic comorbidity, treatment according to guidelines with exposure and reaction prevention was not initially conducted, due to potentially fatal risks to the patient. However, through collaboration with a cardiology clinic, we were able to find an innovative solution which allowed for the continuation of the exposure therapy. This case report demonstrates a successful interdisciplinary collaboration and is intended to sensitize the reader to the need for checking for somatic contraindications before conducting exposure therapy...

BACKGROUND: Patients with cardiac sarcoidosis are at increased risk of ventricular tachycardia/fibrillation. OBJECTIVE: We tested the hypothesis that the wearable cardioverter defibrillator can be used to mitigate the risk of sudden cardiac death among cardiac sarcoidosis patients. METHODS: A retrospective review of the commercial database identified cardiac sarcoidosis patients who wore the wearable cardioverter defibrillator. Evidence for cardiac sarcoidosis diagnosis as well as demographic, co-morbidity and left ventricular ejection fraction were provided by patient clinical records...

BACKGROUND: The wearable cardioverter-defibrillator (WCD) has emerged as a valuable tool to temporarily protect patients at risk for sudden cardiac death (SCD). The aim of this study was to determine the value of the WCD for therapy optimization of heart failure patients. METHODS: One hundred five consecutive patients that received WCD between 4/2012 and 9/2016 were included in the study. All patients were followed for clinical outcome and echocardiographic parameters during WCD therapy and had continued follow-up after WCD therapy, irrespective of subsequent implantable cardioverter-defibrillator (ICD) implantation...

Prevention of sudden cardiac death (SCD) has become an important issue in today's cardiovascular field, together with various developments in secondary prevention of basic cardiac diseases. The importance of the implantable cardioverter defibrillator (ICD) is now widely accepted because it has exhibited significant improvement in patients' prognoses in ischemic and non-ischemic cardiovascular diseases. However, there is an unignorable gap between the ICD indication in the guidelines and real-world high-risk patients for SCD, especially in the acute recovery phase of cardiac injury...

REVIEW
Jonathan Weinstock
The wearable cardioverter defibrillator has been shown to be effective in terminating ventricular arrhythmias in patients at risk for sudden cardiac death. There are numerous scenarios in which implant of a permanent implantable cardioverter defibrillator is temporarily contraindicated or not advisable and a wearable cardioverter defibrillator may be beneficial. There are no prospective randomized studies published that provide conclusive guidance toward the use of the wearable cardioverter defibrillator, and thus, patient management needs to be individualized based on the available data...

BACKGROUND: Class IC antiarrhythmic drugs (IC-AADs) can effectively suppress premature ventricular contractions (PVCs). However, IC-AADs increase mortality in patients with PVCs and left ventricular dysfunction after myocardial infarction. Whether IC-AADs can be safely used to treat premature ventricular contraction-induced cardiomyopathy (PVC-CM) remains to be established. OBJECTIVE: The purpose of this study was to determine the safety and efficacy of IC-AADs in patients suspected of having PVC-CM...

Sudden cardiac death is a potentially fatal clinical event demanding use of emergent intervention such as defibrillation. Over the last 1 decade, development of devices such as implantable and wearable cardioverter defibrillators (WCD) has provided new avenues in the management of sudden cardiac death. Several clinical studies have commented on the therapeutic and preventive aspect of WCD, however, literature describing the device functioning and limitations is limited. In this review study, we describe the technical aspects and limitations of WCD with a focus on identifying potential areas of improvement and framework for future research studies...

Assessment of a permanent risk of life-threatening ventricular arrhythmia in patients with severely reduced left ventricular ejection fraction (LVEF <35%), e. g. after myocarditis, dilated cardiomyopathy, acute myocardial infarction, in patients with postpartum cardiomyopathy or implantable cardioverter-defibrillator (ICD) and cardiac resynchronization treatment plus defibrillator (CRT-D) infection with temporary explantation of the system is a medical challenge. This is time-consuming and unsafe because life-threatening ventricular arrhythmias may occur during the time of risk assessment...

BACKGROUND: The approach to treat device infection in patients with implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy defibrillator (CRT-D) is a challenging procedure. Optimal treatment is complete extraction of the infected device. To protect these patients from sudden cardiac arrest while waiting for reimplantation and to avoid recurrent infection, a wearable cardioverter defibrillator (WCD) seems to be a valuable solution. Therefore, we investigated the management and outcome of patients with ICD or CRT-D infections using the WCD as a bridge to re-implantation after lead extraction procedures...

In-hospital sudden cardiac arrests occurring during nighttime and weekend hours or within unmonitored hospital areas have been reported to have a poorer outcomes than monitored cardiac arrest. This study sought to assess the outcome of in-hospital ventricular tachycardia (VT) and ventricular fibrillation (VF) arrest by time of day, day of week, and within-hospital location when using a wearable cardioverter defibrillator (WCD). We retrospectively identified and reviewed consecutive in-hospital VT/VF arrests from January 2011 to May 2015 experienced by patients wearing a WCD using the manufacturer's postmarket registry...

The wearable cardioverter defibrillator (WCD) is a temporary treatment option for patients with potentially reversible risk of sudden cardiac death. This case demonstrates a pitfall during WCD usage in a pacemaker-dependent patient as well as a possible solution allowing continuation of WCD therapy. Bipolar stimulation may lead to double counting of the WCD detection algorithm resulting in false alarm or inappropriate therapy.
