Use of direct oral anticoagulants in patients on chronic hemodialysis: Contemporary appraisal on the role for patients with atrial fibrillation.

Atrial fibrillation (AF) is common in patients with chronic kidney disease (CKD) undergoing hemodialysis and in this patient population, management in terms of oral anticoagulation (OAC) presents unique challenges due to the increased risk of both thromboembolic events and bleeding complications. The attributable risk of AF for stroke may differ from patients without CKD, raising the question if OAC is indicated at all. Historically, vitamin K antagonists (VKA) have been the standard treatment for anticoagulation in AF; however, direct oral anticoagulants (DOACs) have emerged as an alternative therapeutic option, whereby data from prospective randomised trials with hemodialysis patients is limited resulting in great variability of practice and guideline recommendations.

Incidence and predictors of cardiac arrhythmias in patients with COVID-19 induced ARDS.

Introduction: Recent studies suggest cardiac involvement with an increased incidence of arrhythmias in the setting of coronavirus disease 2019 (COVID-19). The aim of this study was to evaluate the risk of potentially lethal arrhythmias and atrial fibrillation in patients with COVID-19-induced acute respiratory distress syndrome (ARDS) and to elicit possible predictors of arrhythmia occurrence.

Methods And Results: A total of 107 patients (82 male, mean age 60 ± 12 years, median body mass index 28 kg/m) treated for COVID-19-induced ARDS in a large tertiary university hospital intensive care unit between March 2020 and February 2021 were retrospectively analyzed.

Accuracy of Deep Learning Echocardiographic View Classification in Patients with Congenital or Structural Heart Disease: Importance of Specific Datasets.

Introduction: Automated echocardiography image interpretation has the potential to transform clinical practice. However, neural networks developed in general cohorts may underperform in the setting of altered cardiac anatomy.

Methods: Consecutive echocardiographic studies of patients with congenital or structural heart disease (C/SHD) were used to validate an existing convolutional neural network trained on 14,035 echocardiograms for automated view classification.

[Atrial fibrillation in patients with sepsis and non-cardiac infections].

Atrial fibrillation (AF) is by far the most frequent cardiac arrhythmia associated with sepsis and infections. Newly occurring AF due to infections is associated with a deterioration of the prognosis for acute events and also for the long-term prognosis of patients. The risk of developing AF during an infection depends on general (e.

[Cardiac arrhythmias in patients with chronic kidney disease].

Patients with chronic kidney disease are at increased risk for cardiovascular morbidity and mortality, with the increased prevalence of supraventricular and ventricular arrhythmia being an important factor. The underlying pathomechanisms are diverse and mainly cause increasing atrial and ventricular fibrosis with so-called cardiac remodeling. In particular, patients with advanced kidney disease were excluded from many pioneering clinical trials, so there are no clear guidelines in the treatment of cardiac arrhythmia for these patients.

Proarrhythmic Effect of Acetylcholine-Esterase Inhibitors Used in the Treatment of Alzheimer's Disease: Benefit of Rivastigmine in an Experimental Whole-Heart Model.

Several studies suggest QT prolongation and torsade de pointes with acetylcholine-esterase inhibitors. We therefore examined the electrophysiologic profile of donepezil, rivastigmine, and galantamine in a sensitive whole-heart model of proarrhythmia. 34 rabbit hearts were isolated and retrogradely perfused employing the Langendorff setup.

Spotlight on S-ICD™ therapy: 10 years of clinical experience and innovation.

Subcutaneous ICD (S-ICD™) therapy has been established in initial clinical trials and current international guideline recommendations for patients without demand for pacing, cardiac resynchronization, or antitachycardia pacing. The promising experience in 'ideal' S-ICD™ candidates increasingly encourages physicians to provide the benefits of S-ICD™ therapy to patients in clinical constellations beyond 'classical' indications of S-ICD™ therapy, which has led to a broadening of S-ICD™ indications in many centres. However, the decision for S-ICD™ implantation is still not covered by controlled randomized trials but rather relies on patient series or observational studies.

[Subcutaneous implantable cardioverter-defibrillator : Current status and perspectives].

The use of transvenous implantable cardioverter-defibrillators (ICD) for the prevention of sudden cardiac death has been proven in numerous randomized trials. By using a totally subcutaneous ICD (S-ICD) system, it is expected to ensure appropriate protection while avoiding long-term complications associated with transvenous leads, such as systemic infection and electrode dysfunction. Meanwhile, the safety and effectiveness of the S‑ICD has been substantiated by results of large registry studies.
