Intrapericardial Corticosteroids and Colchicine Prevent Pericarditis and Atrial Fibrillation After Epicardial Ablation of Ventricular Arrhythmias.

Background: Postprocedural pericarditis (PP) can occur in up to 29.4% of patients undergoing epicardial catheter ablation of ventricular tachycardia (VT). Despite several proposed strategies to mitigate this adverse outcome, rates of PP and pericarditic pain remain high.

Early Versus Late Atrial Fibrillation Recurrence After Pulsed Field Ablation: Insights From the admIRE Trial.

Background And Aims: Studies have shown correlations between early recurrence (ER) and late recurrence (LR) of atrial arrhythmia after ablation with thermal technologies. This admIRE trial (NCT05293639) subanalysis aims to analyze ER versus LR in patients with paroxysmal atrial fibrillation (PAF) undergoing pulsed field ablation (PFA).

Methods: Patients with symptomatic paroxysmal atrial fibrillation and ≥1 transtelephonic monitoring transmission during the blanking period were included (n=169).

Impact of dispersive patch electrode positioning on safety and efficacy of radiofrequency catheter ablation.

Safe and efficient radiofrequency catheter ablation depends significantly on the proper placement of dispersive patch electrodes (DPEs), on the skin. This viewpoint describes the role of DPE positioning in optimizing lesion creation and reducing the risk of complications. Incorrect DPE placement can lead to suboptimal energy delivery, prolonging the procedure and/or increasing the risk of adverse events, such as steam pops and potentially fatal atrio-oesophageal fistula.
