Background Clinically effective ablation approaches for patients with persistent atrial fibrillation
(AF) are still being debated. So far, ablation targets and strategies beyond pulmonary …

Apelin, a regulatory peptide, is a ligand of the APJ receptor that belongs to the G protein-coupled
receptor family. Apelin and APJ are widely distributed in the body and play potential …

Aims Long-term efficacy following cryoballoon (CB) ablation of atrial fibrillation (AF) remains
unknown. This study describes 5 years follow-up results and predictors of success of CB …

Aims Cerebral embolism is a possible serious complication during catheter ablation of atrial
fibrillation (AF). The purpose of this prospective pilot study was to analyse the incidence and …

Background: Pre-procedural predictors (PP) of atrial fibrillation (AF) recurrence (AFR) after
repeated catheter ablation of AF (RCAF) are unknown. The aim of this study was identification …

Background: The goal of this study was to analyze impact of metabolic syndrome (MetS) and
impaired renal function on long‐term follow‐up after catheter ablation of atrial fibrillation (AF…

Aims Transoesophageal echocardiography (TOE) is often performed before catheter
ablation or cardioversion to rule out the presence of left atrial appendage thrombus (LAT) in …

Pulmonary Vein Stenting. Introduction: Severe pulmonary vein stenosis (PVS) after catheter
ablation of atrial fibrillation (AF) is a well‐recognized complication with a further reported …

Silver nanoparticles (AgNPs) are found in open waters, but the effect of their low concentrations
on an organism’s homeostasis is not fully understood. The aim of the study was to …

The growth hormone (GH) plays a key role in the regulation of metabolic processes in an
