The entirely subcutaneous implantable cardioverter-defibrillator (ICD) system was developed to provide a life-saving defibrillation therapy that does not affect the heart and vasculature. The subcutaneous ICD is preferred over the transvenous ICD for patients with a history of recurrent infection presenting major life-threatening rhythms. In this case report, we describe the first successful in...

Background Dental anesthetic management in implantable cardioverter defibrillator (ICD) recipients with cardiac channelopathies (CCh) can be challenging due to the potential risk of life-threatening arrhythmias and appropriate ICD therapies during procedural time. Objectives The present study assessed hypothesis that use local dental anesthesia 2% lidocaine 1:100,000 epinephrine or without a va...

BACKGROUND Eight randomized trials have evaluated whether the prophylactic use of an implantable cardioverter-defibrillator (ICD) improves survival among patients who are at risk for sudden death due to left ventricular systolic dysfunction but who have not had a life-threatening ventricular arrhythmia. We assessed the cost-effectiveness of the ICD in the populations represented in these primar...

BACKGROUND An implantable cardioverter defibrillator (ICD) may be effective in reducing the risk of sudden cardiac death. The high cost of ICD treatment, however, compared with alternatives raises the question of whether this new technology is an efficient use of scarce health care resources. OBJECTIVE To estimate the incremental cost effectiveness of the implantable cardioverter defibrillato...

BACKGROUND The entirely subcutaneous implantable cardioverter-defibrillator (S-ICD) is the first implantable defibrillator that avoids placing electrodes in or around the heart. Two large prospective studies (IDE [S-ICD System IDE Clinical Investigation] and EFFORTLESS [Boston Scientific Post Market S-ICD Registry]) have reported 6-month to 1-year data on the S-ICD. OBJECTIVES The objective o...

A 70-year-old woman had a single-chamber implantable cardioverter-defibrillator (ICD) inserted four years previously for ventricular sustained tachycardia caused by ischaemic heart disease. She was admitted for assessment of grade II dyspnoea and muteness of the ICD. Chest X-ray showed that the generator had been rotated clockwise through almost 180°, and the lead displaced and fully wrapped ar...

Introduction: Metallic artifacts due to pacemaker/ implantable cardioverter defibrillator (ICD) leads in CT images can produce artifactual uptake in cardiac SPECT/CT images. The aim of this study was to determine the influence of the metallic artifacts due to pacemaker and ICD leads on myocardial SPECT/CT imaging. Methods: The study included 9 patients wh...

The clinical management of implantable cardioverter-defibrillator (ICD) patients involves successful medical and psychosocial care to reduce mortality and morbidity. Desirable quality of life (QoL) and psychosocial outcomes for ICD patients are achievable for a majority of ICD patients. Patient critical events, such as ICD shocks or ICD recalls, may occur that can dramatically alter the course ...

OBJECTIVES The present study was designed to explore the 8-year survival benefit of a nonresynchronization implantable cardioverter-defibrillator (ICD) according to a simple risk stratification score. BACKGROUND There is limited information regarding factors that predict the benefit of primary prevention with an ICD during long-term follow-up. METHODS This study used a previously developed ...

Cardiac contractility modulation (CCM) is a relatively new electrical therapy for heart failure patients with reduced ejection fraction. The majority of patients eligible for CCM will also need an implantable cardioverter-defibrillator (ICD). To-date, three pacing electrodes are mandatory for CCM therapy because the current CCM signal delivery algorithm requires sequential intracardiac sensing ...
