Virtual Reality for Sedation During Atrial Fibrillation Ablation in Clinical Practice: Observational Study.

Background: Connected devices are dramatically changing many aspects in health care. One such device, the virtual reality (VR) headset, has recently been shown to improve analgesia in a small sample of patients undergoing transcatheter aortic valve implantation.

Objective: We aimed to investigate the feasibility and effectiveness of VR in patients undergoing atrial fibrillation (AF) ablation under conscious sedation.

Impact of the atrial lead pacing site regarding atrial fibrillation onset in patients with sinus node dysfunction.

Symptomatic sinus node disease (SND) most frequently requires the implantation of a dual chamber pacemaker of which the right atrial lead is generally implanted in the right atrial appendage (RAA) or the lateral wall (LW).The aim of this retrospective study was to evaluate the impact of the right atrial lead pacing site regarding the onset of AF in patients with SND. RESULTS: 126 patients were included (53% males; 76 yo).

[Screening and diagnosis of atrial fibrillation].

Screening and diagnosis of atrial fibrillation. Screening for atrial fibrillation (AF) is crucial as this arrhythmia is asymptomatic in a third of patients and 5% of patients present a stroke as the first manifestation of their AF. The European Society of Cardiology recommends opportunistic screening of AF in patients over 65 years of age and systematically in patients over 75 years of age.

Hypnosis Versus Placebo During Atrial Flutter Ablation: The PAINLESS Study: A Randomized Controlled Trial.

Objectives: The aim of this study was to assess the superiority of hypnosis versus placebo on pain perception and morphine consumption during typical atrial flutter (AFL) ablation.

Background: AFL ablation commonly requires intravenous opioid for analgesia, which can be associated with adverse outcomes. Hypnosis is an alternative technique with rising interest, but robust data in electrophysiological procedures are lacking.

Prognostic value of Charlson Comorbidity Index in the elderly with a cardioverter defibrillator implantation.

Background: Elderly patients are often underrepresented in implantable cardioverter defibrillator (ICD) trials, and ICD implantation in patients ≥75 years consequently remains controversial. We aimed to evaluate mortality, appropriate ICD therapy rates and survival gain in an elderly population after risk stratification according to the Charlson Comorbidity Index (CCI).

Methods: This monocentric retrospective study included elderly ICD patients ≥75 years.

Baroreflex sensitivity assessed with the sequence method is associated with ventricular arrhythmias in patients implanted with a defibrillator for the primary prevention of sudden cardiac death.

Background: Left ventricular ejection fraction lacks accuracy in predicting sudden cardiac death, resulting in unnecessary implantation of cardioverter defibrillators for the primary prevention of sudden cardiac death. Baroreflex sensitivity could help to stratify patients at risk of ventricular arrhythmia.

Aim: To assess the association between cardiac baroreflex sensitivity and ventricular arrhythmias in patients implanted with an implantable cardioverter defibrillator for the primary prevention of sudden cardiac death after myocardial infarction.

Contractibility sensor signal evolution predicts cardiovascular events in patients with cardiac resynchronization therapy.

Background: While a multicentre trial has demonstrated that the SonR™ contractibility sensor is as effective as echocardiography-guided optimization at improving response to cardiac resynchronization therapy, an association between SonR™ values and clinical endpoints has not been established.

Aims: The primary objective was to assess the predictive value of SonR™ signal evolution regarding cardiovascular events in patients implanted with a cardiac resynchronization therapy device. The secondary objective was to evaluate whether SonR™ signal evolution was associated with cardiovascular death.

Twenty-four-hour ambulatory ECG monitoring relevancy in myotonic dystrophy type 1 follow-up: Prognostic value and heart rate variability evolution.

Background: Patient prognosis in type 1 myotonic dystrophy (DM1) is very poor. Annual 24-hour holter ECG monitoring is recommended but its relevance is debated. Main objective was to determine whether holter ECG parameters could predict global death in DM1 patients and secondarily to assess whether they could predict cardiovascular events and sudden cardiac death, to compare DM1 patients and healthy controls, and to assess their evolution in DM1 over a 5-year period.

Left ventricular longitudinal strain impairment predicts cardiovascular events in asymptomatic type 1 myotonic dystrophy.

Background: Type 1 myotonic dystrophy (DM1) patients' prognosis is very poor. Up until now, only a few prognostic factors for cardiovascular events have been identified, and they are predictive of end-stage disease. The aim was to assess the prognostic value of global longitudinal strain (GLS) for cardiovascular events in asymptomatic DM1 patients.

Apical left ventricular myocardial dysfunction is an early feature of cardiac involvement in myotonic dystrophy type 1.

Introduction: Left ventricular (LV) dysfunction is a major prognostic determinant in myotonic dystrophy type 1 (DM1). Therefore, markers of early-stage LV impairment may be useful. The aim of this study was to evaluate 2D echocardiographic LV strain in a cohort of DM1 patients with preserved left ventricular ejection fraction (LVEF) and to compare the results with matched controls.

When is a child with status epilepticus likely to have Dravet syndrome?

Purpose: To identify clinical risk factors for Dravet syndrome (DS) in a population of children with status epilepticus (SE).

Material And Methods: Children aged between 1 month and 16 years with at least one episode of SE were referred from 6 pediatric neurology centers in Switzerland. SE was defined as a clinical seizure lasting for more than 30min without recovery of normal consciousness.

Replication of association between a SCN1A splice variant and febrile seizures.

In the present study, we assessed a SCN1A single nucleotide polymorphism (SNP) (rs3812718, IVS5N+5 G>A), first analyzed by Schlachter et al. We genotyped 164 patients with febrile seizures (FS) [of those 62 adults with focal epilepsy (FEFS(+)) and 102 children with pure FS (Pure FS)] and 199 matched controls. Moreover, we also tested a third subgroup of 113 patients with focal epilepsy syndromes without a history of FS (FEFS(-)); they all were Caucasian.

A case of SUDEP in a patient with Dravet syndrome with SCN1A mutation.

A boy with a clinical history of pharmacologically resistant Dravet syndrome died suddenly after falling asleep. The autopsy concluded that the cause of death was sudden unexpected death in epilepsy (SUDEP). Postmortem molecular analysis of the SCN1A gene by multiplex ligation-dependent probe amplification (MLPA), high-resolution melting curve analysis (HRMCA), and sequencing revealed a frameshift duplication of adenosine at position 504.

Management of subacute and delayed right ventricular perforation with a pacing or an implantable cardioverter-defibrillator lead.

The development of small-diameter active fixation pacing and implantable cardioverter-defibrillator leads may be associated with increased risk for delayed right ventricular perforation. The management of this unforeseen complication has been poorly described. Eleven successive patients referred for right ventricular subacute or delayed perforation (no evidence of lead perforation at the time of the procedure, perforation of the right ventricle diagnosed > or =5 days after implantation) were reviewed.

Chemokine analogues show suitable stability for development as microbicides.

New prevention strategies are urgently needed to slow the spread of the HIV/AIDS pandemic, and in the absence of an effective vaccine, there is hope that "microbicides"-HIV inhibitors applied to mucosal surfaces before sexual intercourse-may be able to make an impact. Because developing countries are at the center of the epidemic, affordability and stability during storage are key criteria for candidate microbicides. Furthermore, because formulation strategies that provide long-duration protection after a single dose may enhance acceptability and compliance, stability in the vaginal environment and in the presence of semen should also be considered.
