Atrial fibrillation in chronic heart failure patients with reduced ejection fraction: The CHECK-HF registry.

Background: Atrial fibrillation (AF) is common in chronic heart failure (HF) patients and influences the choice and effects of drug and device therapy. In this large real-world HF registry, we studied whether the presence of AF affects the prescription of guideline-recommended HF therapy.

Methods: We analyzed 8253 patients with chronic HF with reduced ejection fraction (HFrEF) from 34 Dutch outpatient clinics included in the period between 2013 and 2016 treated according to the 2012 ESC guidelines.

Contemporary Drug Treatment of Chronic Heart Failure With Reduced Ejection Fraction: The CHECK-HF Registry.

Objectives: This study investigated adherence to drug therapy guidelines in heart failure (HF) with reduced left-ventricular ejection fraction (LVEF) of <40% (heart failure with reduced ejection fraction [HFrEF]), in which evidence-based treatment has been established.

Background: Despite previous surveys of HF, important uncertainties remain regarding guideline adherence in a representative real-world population.

Methods: A cross-sectional registry in 34 Dutch HF outpatient clinics that included 10,910 patients with the diagnosis of HF was examined.

Longitudinal echocardiographic and clinical follow-up of patients undergoing mitral valve surgery without concomitant tricuspid valve repair.

Background: In patients with mild to moderate functional tricuspid regurgitation (TR) and absence of right ventricular dysfunction or tricuspid annulus (TA) dilatation, there is currently no indication for concomitant tricuspid valve (TV) repair during elective mitral valve (MV) surgery. However, long-term results are conflicting. Here, we sought to determine the clinical outcome of this cohort, the rate of TR progression after MV surgery and the role of MV aetiology.

P wave recognition and atrial stimulation with fractally iridium coated VDD single pass leads.

Unlabelled: The bottleneck of VDD systems is the reliable detection of the small atrial signals by a floating atrial electrode. Fractally iridium coated electrodes offer excellent sensing and pacing performance. In this study, the performance of such a floating atrial lead in P wave sensing and synchronous ventricular stimulation was examined.
