Silent brain infarcts impact on cognitive function in atrial fibrillation.

Aims: We aimed to investigate the association of clinically overt and silent brain lesions with cognitive function in atrial fibrillation (AF) patients.

Methods And Results: We enrolled 1227 AF patients in a prospective, multicentre cohort study (Swiss-AF). Patients underwent standardized brain magnetic resonance imaging (MRI) at baseline and after 2 years.

Outcomes of electrical injuries in the emergency department: a 10-year retrospective study.

Objective: Electrical injuries are challenging to assess and current guidelines are based on few studies and case reports. Recommendations on cardiac monitoring were published for certain risk factors, but indications for hospital observation are less clear. Furthermore, the risk of late arrhythmias is not known.

Head-to-head comparison of two-dimensional and three-dimensional echocardiographic methods for left atrial chamber quantification with magnetic resonance imaging.

Background: Limited data are available on the accuracy of quantification methods for left atrial (LA) volumes using two-dimensional (2D) and particularly real-time three-dimensional echocardiographic (RT3DE) methods in comparison with a reference standard. The aim of this study was to perform a head-to-head comparison between 2D and RT3DE methods with magnetic resonance imaging (MRI) as the reference standard.

Methods: LA volumes derived from 2D echocardiographic methods (i.
