Electroanatomic and Pathologic Right Ventricular Outflow Tract Abnormalities in Patients With Brugada Syndrome.

Background: The prevalence and significance of structural abnormalities in Brugada syndrome (BrS) are still largely debated.

Objectives: The authors investigated the relationship between genetic background, electroanatomic abnormalities, and pathologic substrate in BrS.

Methods: They performed 3-dimensional electroanatomic unipolar and bipolar mapping in 30 patients with BrS.

Long-term prognostic value of delirium in elderly patients with acute cardiac diseases admitted to two cardiac intensive care units: a prospective study (DELIRIUM CORDIS).

Background: Delirium is a frequent in-hospital complication in elderly patients, and is associated with poor clinical outcome. Its clinical impact, however, has not yet been fully addressed in the setting of the cardiac intensive care unit (CICU). The present study is a prospective, two-centre registry aimed at assessing the incidence, prevalence and significance of delirium in elderly patients with acute cardiac diseases.

Safety of single transseptal puncture for ablation of atrial fibrillation: retrospective study from a large cohort of patients.

Introduction: Transseptal puncture (TSP) is the conventional approach to assess the left atrial chamber. This technique has been widely used in interventional cardiology and, in the last years, this approach is mostly applied to electrophysiologic procedures. For atrial fibrillation (AF) ablation, two or more transseptal sheaths are often positioned in the left atrium in the majority of centers, therefore requiring two or more transseptal punctures.
