BACKGROUND: In the first 24h after pacemaker or implantable cardioverter/defibrillator (ICD) implantation or replacement, the occurrence of hematoma and pain in the surgically treated region is not infrequent and may result in re-intervention and/or more severe complications, such as infections. Currently, the post-implant phase management is very empiric. The aim of this study was to test the clinical applicability and usefulness of an external close-circuit cooling system for the management of the early post-implant period in patients with high risk of hematoma due to anticoagulant and/or antiplatelet therapy...

Aims: Cardiac sarcoidosis (CS) is associated with a poor prognosis. Important features of CS include heart failure, conduction abnormalities, and ventricular arrhythmias. Ventricular tachycardia (VT) is often refractory to antiarrhythmic drugs (AAD) and immunosuppression. Catheter ablation has emerged as a treatment option for recurrent VT. However, data on the efficacy and outcomes of VT ablation in this context are sparse. Methods and results: A systematic search was performed on PubMed, EMBASE, and Cochrane database (from inception to September 2016) with included studies providing a minimum of information on CS patients undergoing VT ablation: age, gender, VT cycle length, CS diagnosis criteria, and baseline medications...

BACKGROUND: T wave amplitudes during ventricular repolarization in the lead aVR (TAaVR) are shown to be associated with adverse cardiac events in patients with several cardiovascular diseases, such as postmyocardial infarction. However, the utility of TAaVR has not been previously evaluated in patients with cardiomyopathy who have received implantable cardioverter defibrillators (ICD). Patients with ischemic or nonischemic cardiomyopathy (ICM or NICM, respectively) and who received an ICD may experience worsening of their condition due to the introduction of electric shock during treatment...

BACKGROUND: Little is known about the suitability of implantable cardioverter defibrillator (ICD) implantation in patients with cardiac sarcoidosis (CS). We evaluated the efficacy of ICD implantation in patients with CS, including suspected CS, compared with those with idiopathic dilated cardiomyopathy (DCM). METHODS: A total of 102 consecutive patients with definite CS, suspected CS, or DCM who underwent ICD implantation were enrolled. The endpoint was the first documentation of appropriate ICD therapy for ventricular tachyarrhythmias...

EDITORIAL
Jessica Ford
The literature surrounding posttraumatic stress symptoms (PSS) and anxiety among patients living with implantable cardioverter defibrillators (ICD) is becoming increasingly sophisticated with evidence linking traumatic stress and anxiety to cardiovascular outcomes, examinations of psychosocial treatment of PSS and anxiety, and predictive modeling all contributing to a more nuanced understanding of the predictors, course, and treatment of PSS and anxiety among ICD patients. In this issue of PACE, Habibovic, Denollet, and Pedersen report secondary analyses from the WEBCARE trial data in which the author employed Latent Class Analysis (LCA) to identify trajectories of trauma and anxiety symptoms among patients implanted with ICDs across the 12-month post-implant period and examined associations between the identified trajectories and demographic, clinical, and psychological characteristics of the participants...

A patient with Brugada Syndrome implanted with subcutaneous cardioverter defibrillator (S-ICD) had oversensing episodes treated with S-ICD shocks. Comparable artefacts weren't evocable with S-ICD pocket manipulation. The fluoroscopy excluded S-ICD macroscopic damage. The device extraction revealed undamaged pulse generator and connector, but the lead was inappropriately tunnelled under the sixth rib. Then the S-ICD malfunction was due to lead microscopic damage caused by lead rubbing the rib surface. This article is protected by copyright...

BACKGROUND: Implantable cardioverter defibrillator (ICD) therapy is first-line treatment for the primary and secondary prevention of sudden cardiac death. Despite the unequivocal medical benefits, living with an ICD may affect patients' psychological functioning and general well-being. We examined the trajectories of symptoms of posttraumatic stress disorder (PTSD) and anxiety in patients with an ICD and the vulnerability factors associated with an increased risk of symptoms of PTSD and anxiety...

Using an implantable cardioverter-defibrillator (ICD) in small children is still challenging, but the need is increasing. We present a new approach to overcoming ICD problems caused by growth in infants. A redundant ICD lead was fixed to the superior border of the sternum and tunneled retrosternally to the subxiphoid region for connection to the generator, which was placed in a pocket beneath the left transversus abdominis muscle. The redundant retrosternal part of the lead straightened during growth, while cardiac coverage by the cardioversion energy field and the defibrillation vector were maintained appropriately...

Implantable cardioverter-defibrillator (ICD) is the standard of care for prevention of sudden cardiac death (SCD) in high-risk patients. For primary prevention of SCD, in patients with ischaemic heart disease, there is more robust data on the effect of ICD therapy compared with patients with non-ischaemic heart disease, but current real-life practice may differ substantially. The aim of this European Heart Rhythm Association survey was to evaluate the clinical practice regarding implantation of ICD for primary prevention among European countries in patients with non-ischaemic and ischaemic heart disease...

Aims: Cardiac magnetic resonance (CMR) imaging in patients with implanted cardiac devices is often limited by device-related imaging artefacts. Limitations can potentially be overcome by employing a broadband late gadolinium enhancement (LGE)-CMR imaging technique. The purpose of this study was to investigate the relationship between implanted cardiac devices and the optimal frequency offset on broadband LGE-CMR imaging to increase the artefact-free visibility of myocardial segments. Methods and results: A phantom study was performed to characterize magnetic field disturbances related to 15 different cardiac devices...

INTRODUCTION: The wearable cardioverter defibrillator (WCD) may allow stabilization until reassessment for an implantable cardioverter defibrillator (ICD) among high-risk HF patients. However, there are limited data on the WCD benefit in the acute decompensated HF setting. METHODS AND RESULTS: The Study of the Wearable Cardioverter Defibrillator in Advanced Heart-Failure Patients (SWIFT) was a prospective clinical trial carried out at two medical centers. Patients hospitalized with advanced HF symptoms and reduced left ventricular ejection function (LVEF) were enrolled and prescribed a WCD prior to discharge for a total of 3 months...

INTRODUCTION: Inappropriate implantable cardioverter-defibrillator (ICD) shocks, commonly caused by atrial fibrillation (AF), are associated with an increased mortality. Because impaired left atrial (LA) function predicts development of AF, we hypothesized that impaired LA function predicts inappropriate shocks beyond a history of AF. METHODS AND RESULTS: We prospectively analyzed the association between LA function and incident inappropriate shocks in primary prevention ICD candidates...
