Randomized Controlled Trial
Higher burden of supraventricular ectopic complexes early after catheter ablation for atrial fibrillation is associated with increased risk of recurrent atrial fibrillation.
Early identification of patients who could benefit from early re-intervention after catheter ablation is highly warranted. Our aim was to investigate the association between post-procedural burden of supraventricular ectopic complexes (SVEC) and the risk of long-term atrial fibrillation (AF) recurrence. ⋯ Our results indicate that post-procedural ectopy burden is highly associated with long-term AF recurrence and could be a potent risk marker for selection of patients for early re-ablation. Development of future ablation risk stratification and strategies should include focus on post-procedural ectopy burden.

Multicenter Study Comparative Study Observational Study
Implantable cardioverter-defibrillator therapy among patients with non-ischaemic vs. ischaemic cardiomyopathy for primary prevention of sudden cardiac death.
The magnitude of benefit related to implantable cardioverter defibrillator (ICD) therapy for primary prevention of sudden cardiac death (SCD) in non-ischaemic cardiomyopathy (NICM) and ischaemic cardiomyopathy (ICM) has not been evaluated extensively in clinical practice. ⋯ NCT 01992458.

Atrial fibrillation (AF) is the most common arrhythmia and prevalence increases with age. Patients with AF have a high risk of stroke, and screening for AF is recommended in all people aged 65 years or older to identify patients eligible for stroke prevention. A handheld, single-lead electrocardiogram (ECG) device can be used for systematic screening in the population at risk. The objective of this study is to estimate the cost-effectiveness of screening for AF in primary care with the MyDiagnostick® during seasonal influenza vaccination in the Netherlands. ⋯ Screening for AF in primary care with a handheld, single-lead ECG during seasonal influenza vaccination is very likely to be cost saving for identifying new cases of AF in the Dutch population aged 65 years and over. Active screening for AF with a single-lead, handheld ECG device during seasonal influenza vaccination could be implemented in primary care.

Observational Study
Relation of renal dysfunction with incident atrial fibrillation and cardiovascular morbidity and mortality: The PREVEND study.
Renal dysfunction is a risk factor for cardiovascular disease, including atrial fibrillation (AF) and mortality. However, the exact pathobiology linking different renal dysfunction measures, such as albumin excretion or glomerular filtration rate (GFR), to cardiovascular- and AF risk are unclear. In this study, we investigated the association of several renal function measures and incident AF, and whether the relation between renal measures and outcomes is modified by AF. ⋯ In this community-based cohort, increased albumin excretion, and not GFR, was associated with incident AF, independent of established cardiovascular risk factors. Incidence of AF did not largely alter the association of renal dysfunction and cardiovascular outcomes.

Catheter ablation to achieve posterior left atrial wall (PW) isolation may be performed as an adjunct to pulmonary vein isolation (PVI) in patients with persistent atrial fibrillation (AF). We aimed to determine whether routine adenosine challenge for dormant posterior wall conduction improved long-term outcome. ⋯ Posterior left atrial wall isolation in addition to PVI is a readily achievable ablation strategy in patients with persistent AF. Routine adenosine challenge for dormant posterior wall conduction was associated with an improvement in the success of catheter ablation for persistent AF.
