BACKGROUND: Patients with an implantable cardioverter defibrillator (ICD) retain a scar and a bump at the site of implant. This may lead to body image concerns (BICs) that influence patients' quality of life. Few studies have examined the prevalence and impact of BICs post implant, prompting us to conduct a scoping review of the field. METHODS: We searched the Medline, Embase, PsycINFO and Cinahl databases in August 2016 and repeated May 2017. Included were studies reporting on patients ≥ 18 years, an ICD implant (transvenous, subcutaneous, or ICD with cardiac resynchronization therapy (CRT-D), reporting on BICs, and published in peer-reviewed English-language journals...

Idiopathic chronic diarrhea (ICD) is a common ailment affecting captive rhesus macaques ( Macaca mulatta). ICD cases are characterized by diarrhea in the absence of commonly identified diarrheal pathogens and multiple recurrences even after supportive therapy. Histologically, the disease is characterized by lymphoplasmacytic colitis. We identified 35 rhesus macaques euthanized for ICD during a 7-month period and described demographic, clinical, histologic, and immunologic commonalities. We found a trend of historic Campylobacter spp...

Why? The potential risks of sport for an ICD recipient include appropriate and inappropriate shocks, device damage and worsening of the underlying cardiopathy. These risks should be compared to the physical and psychological benefits of exercise. Where? Due to different medico-legal contexts and considering the results of recent studies, the new US guidelines are more permissive than the European guidelines regarding sport practice in ICD recipients. Who? The underlying context (structural or electrical cardiopathy, psychological impact) should be assessed before any decision is taken...

BACKGROUND: The subcutaneous implantable cardioverter-defibrillator (S-ICD) lacks the antitachycardia pacing (ATP) capability of tranvenous ICDs (TV-ICD). S-ICD patient selection can be challenging as some patients may benefit from ATP. We aim to identify clinical predictors of ATP benefit, in order to improve patient selection for S-ICD or TV-ICD therapy. METHODS: De novo single- and dual-chamber TV-ICD patients implanted between March 2011 and December 2015 were included...

A 41-year-old woman was visiting Oxford, where she had a sudden cardiac arrest. Cardiopulmonary resuscitation was started by a bystander until the paramedics arrived, who found her in ventricular fibrillation, and delivered three shocks. After 28 min she had return of spontaneous circulation. Emergency coronary angiography revealed normal coronary arteries. Echocardiography followed by a cardiac MRI showed non-dilated left ventricles with no evidence of late gadolinium enhancement. She had a single-chamber implantable-cardioverter defibrillator (ICD)...

BACKGROUND: The subcutaneous implantable cardioverter defibrillator (S-ICD) has been established as a valuable alternative to transvenous ICD for prevention of sudden cardiac death. The system automatically chooses the optimal sensing vector. However, during follow-up and especially after device replacement we observed a change of the suggested sensing vector in automatic setup. Therefore, we analyzed frequency and reasons of vector change and its impact on inappropriate shocks (iAS)...

INTRODUCTION: Recognition of implantable cardioverter defibrillator (ICD) lead malfunction before occurrence of life threatening complications is crucial. We aimed to assess the effectiveness of remote monitoring associated or not with a lead noise alert for early detection of ICD lead failure. METHODS: From October 2013 to April 2017, a median of 1224 [578-1958] ICD patients were remotely monitored with comprehensive analysis of all transmitted materials. ICD lead failure and subsequent device interventions were prospectively collected in patients with (RMLN) and without (RM) a lead noise alert (Abbott SecureSense™ or Medtronic Lead Integrity alert™) in their remote monitoring system...

BACKGROUND: Remote monitoring (RM) is an established technology integrated into routine follow-up of patients with implantable cardioverter-defibrillator (ICD). Current RM systems differ according to transmission frequency and alert definition. OBJECTIVE: We aimed to compare time difference between detection and acknowledgement of clinically relevant events between four RM systems. METHODS: We analyzed time delay between detection of ventricular arrhythmic and technical events by the ICD and acknowledgement by hospital staff in 1...

Although medical students are rarely instructed in traffic medicine in Germany, they are obliged to inform their patients about their fitness to drive after having become a medical doctor. This article gives an overview on the fitness to drive for patients with syncope by referring to the driving license regulation and the current guidelines released by the department of traffic. The driving license regulation distinguishes between group 1 and group 2 drivers. Group 1 drivers drive vehicles with a total weight less than 3...
