The year 2023 has been extremely rich in new publications in the various subfields of cardiology. Furthermore, the European Society of Cardiology (ESC) has issued revised guidelines focused on the management of acute coronary syndrome (ACS) and endocarditis, as well as an update on the recommendations for the management of heart failure and cardiovascular prevention. The most significant updates according to the Cardiology Department of CHUV are summarized in this review article., Competing Interests: les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

The year of 2022 was marked by many novelties in the fields of interventional cardiology, heart failure, electrophysiology, cardiac imaging, and congenital heart disease. These advances will certainly change our daily practice, on top of improving the diagnosis and treatment of many heart conditions. In addition, the European Society of Cardiology has updated its guidelines on pulmonary hypertension, ventricular arrhythmias and sudden death, cardiovascular assessment of patients undergoing non-cardiac surgery. The members of the Cardiology division of Lausanne University Hospital (CHUV) here present the publications which they considered to be the most important of the past year., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Atrial fibrillation (AF) is the most common arrhythmia encountered in adults; it is associated with a significant morbidity and mortality. Obesity is a risk factor contributing to AF occurrence. Recently, interest has focused on epicardial adipose tissue (EAT), defined as a fatty deposit located between the epicardium and the visceral pericardium. Its characteristics are distinct from classic adipose deposits: it infiltrates the epicardial myocardium and secretes cytokines, which modulate cardiomyocyte electrophysiology and cardiac remodeling. Different studies show that EAT can be an independent risk factor for AF and that EAT thickness, as measured by CT or MRI, could predict the presence, severity and recurrence of AF., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Cardiac arrhythmias are common conditions that often manifest themselves intermittently, thus complicating their diagnosis, particularly in the ambulatory setting. Recently, technological advances have facilitated public access to health applications and devices. This article reviews the available technologies and analyses their usefulness for the diagnosis of arrhythmias in the context of everyday clinical practice.
