Beside heart failure and metabolic syndrome, atrial fibrillation is termed the cardiovascular epidemic of the twenty-first century. Its increased morbidity and mortality is alarming. The present, most effective therapy of atrial fibrillation is catheter ablation. Successful ablation of atrial fibrillation prevents the occurrence and progression of electrical, structural and mechanic myocardium remodelling, improves function of the left ventricle, and prevents the risk of thrombembolism. Onset of sinus rhythm activates the reversal remodelling leading to wall reconstruction and atrium reduction. The paper reviews the technique and presents own experience with catheter ablation.

Myocardial extracellular volume fraction (ECV) measured via MRI serves as a quantitative indicator of myocardial fibrosis. However, accurate measurement of ECV using MRI in the presence of AF is challenging. Meanwhile, CT could be a promising alternative tool for measuring ECV regardless of sinus rhythm or AF.

Introduction: Atrial fibrillation (AF), a common heart rhythm abnormality, is linked to a higher risk of stroke. Traditionally, warfarin has been the primary anticoagulation treatment for reducing the stroke risk. The new standard of treatment by direct oral anticoagulants (DOACs) offers greater benefits including improved efficacy and fewer adverse effects with reduced monitoring.

Atrial fibrillation (AF) ablation is associated with a lower likelihood of death and surgical heart failure (HF) interventions in patients with HF. This effect is mainly driven by reduced all cause and cardiovascular death following ablation. Ablation also results in improved left ventricular (LV) function, decreased AF burden and AF regression.

Purpose To assess the predictive value of left atrial (LA) fast long-axis strain derived from cardiac MRI for thrombotic events (TEs) in individuals with hypertrophic cardiomyopathy (HCM). Materials and Methods This secondary analysis of an ongoing prospective trial (Chinese Clinical Trial Registry: ChiCTR1900024094) included consecutive participants with HCM without atrial fibrillation (AF) who underwent cardiac MRI from January 2012 to December 2020. The LA fast long-axis strain was obtained by semiautomatically tracking the distance between the atrioventricular junction and the midposterior LA wall.

Introduction: Cardiac Amyloidosis (CA) is characterised by amyloid fibril deposits causing heart failure (HF). Lumbar spinal stenosis (LSS) is recognised as a potential red flag for CA, but the association remains underexplored in large-scale studies.
Methods: This nationwide registry-based cohort study in Denmark included subjects ≥60 years with a history of LSS surgery.
