Article Synopsis
  • Pulsed field ablation (PFA) is gaining popularity as a treatment for atrial fibrillation, but its impact on hemolysis (destruction of red blood cells) has not been thoroughly studied.
  • In this study involving 145 patients receiving PFA and 70 patients undergoing radiofrequency ablation, significant hemolysis was found predominantly in the PFA group, with 94.3% affected compared to just 6.8% in the radiofrequency group.
  • Higher numbers of PFA deliveries correlated with increased hemolysis severity, with notable increases in biomarkers indicating red blood cell damage and renal function impacts, especially in patients with lower baseline kidney function.

Article Synopsis
  • Catheter ablation for atrial fibrillation (AF) is the most common procedure in electrophysiology, aiming to isolate pulmonary veins, but there is insufficient data on severe complications worldwide.
  • A study involved collecting and analyzing data from 23 centers with 33,879 procedures to determine the incidence and management of severe complications during AF ablation.
  • The study found that while severe complications like tamponade and stroke have a low incidence, factors like age, gender, and procedure duration play a role in their occurrence; most patients with complications were discharged after about 5 days.

Introduction: Pulmonary vein isolation (PVI) using radiofrequency ablation (RFA) is an established treatment strategy for atrial fibrillation (AF). To improve PVI efficacy and safety, high-power short-duration (HPSD) ablation and pulsed-field ablation (PFA) were recently introduced into clinical practice. This study aimed to determine the extent of myocardial injury and systemic inflammation following PFA, HPSD, and standard RFA using established biomarkers.

Background: Ventricular tachycardia (VT) originating in the right ventricular outflow tract (RVOT) is the most common form of idiopathic VT. Catheter ablation of right ventricular outflow tract tachycardia (RVOT-VT) is associated with high success rates. However, non-inducibility of VT on electrophysiological (EP) study can severely impact ablation outcome.

Aims: This retrospective study sought to compare complication rates and efficacy of power-controlled very high-power short-duration (vHPSD) and conventional catheter ablation in a large cohort of patients with atrial fibrillation (AF).

Methods And Results: We analyzed 1115 consecutive patients with AF (38.7% paroxysmal, 61.

Article Synopsis
  • Bipolar radiofrequency ablation (B-RFA) is a treatment for heart problems when other therapies don't work.
  • A study found it was effective in many patients with serious heart issues, and most had good results after the treatment.
  • Combining different types of B-RFA techniques helped make bigger lesions, which is better for treatment, but some complications can happen.

Background: Early recurrence of atrial tachyarrhythmia (ERAT) is common after radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF), but its clinical significance in patients with persistent AF remains unclear. We sought to determine the predictive value of ERAT for rhythm outcome after RFCA for persistent AF.

Methods: The study included 207 consecutive patients (mean age 66.
