Background: Initial clinical studies of pulsed field ablation (PFA) to treat atrial fibrillation (AF) indicated a >90% durability rate of pulmonary vein isolation (PVI). However, these studies were largely conducted in single centers and involved a limited number of operators. The electrophysiological findings and outcomes in patients undergoing repeat ablation after an initial PF ablation for AF are incompletely understood.

Heart failure (HF) increases the risk of developing atrial fibrillation (AF), leading to increased morbidity and mortality. Therefore, better prediction of this risk may improve treatment strategies. Although several predictors based on clinical data have been developed, the establishment of a transcriptome-based predictor of AF incidence in HF has proven to be more problematic.

Aims: Cavotricuspid isthmus (CTI) ablation is the current ablation treatment for typical atrial flutter (AFL). However, post-ablation atrial tachyarrhythmias, mostly in the form of atrial fibrillation (AF), are frequently observed after CTI ablation. We aimed to evaluate the effectiveness and safety of concomitant or isolated pulmonary vein isolation (PVI) in patients with typical AFL scheduled for ablation.

Background: The ability to predict recovery of left ventricular ejection fraction (LVEF) in response to guideline-directed therapy among patients with nonischemic cardiomyopathy is desired. We sought to determine whether left ventricular endocardial unipolar voltage measured during invasive electroanatomic mapping could be used to predict LVEF recovery among those with recent-onset nonischemic cardiomyopathy.

Methods: We analyzed the left ventricular voltage maps of patients included in the eMAP trial (Electrogram-Guided Myocardial Advanced Phenotyping; NCT03293381), a prospective, nonrandomized, interventional trial conducted at 2 institutions between 2017 and 2020.

Background And Aims: Prophylactic implantable cardioverter-defibrillators (ICDs) are not recommended until left ventricular ejection fraction (LVEF) has been reassessed 40 to 90 days after an acute myocardial infarction. In the current therapeutic era, the prognosis of sustained ventricular arrhythmias (VAs) occurring during this early post-infarction phase (i.e.

Background: Learning to interpret electrocardiograms (ECGs) is a crucial objective in medical education. Despite its importance, errors in ECGs interpretation are common, and the optimal teaching methods have not yet been clearly established.

Objectives: To evaluate students' confidence in ECGs analysis and their opinion on current teaching methods, and to assess the effectiveness of a new ECG educational approach.

Background: Pacemaker implantation combined with atrioventricular node ablation (AVNA) is a well-established strategy for uncontrolled atrial arrhythmias. Limited data are available regarding His bundle pacing (HBP) and left bundle branch area pacing (LBBAP) in this setting.

Aim: To compare the outcomes of HBP and LBBAP in patients undergoing pacemaker implantation combined with AVN in routine clinical practice.

Article Synopsis
  • Pulsed field ablation (PFA) is a new method for treating atrial fibrillation (AF) that focuses on ablating heart tissue while minimizing harm to nearby structures.
  • In the MANIFEST-17K study, data from 106 centers involved 17,642 patients and showed no serious complications like esophageal damage, with only a 1% major complication rate.
  • The results suggest that PFA has a strong safety profile and may change how AF is treated, compared to traditional thermal ablation methods.

Background: Idiopathic ventricular fibrillation (IVF) can be associated with undetected distinct conditions such as microstructural cardiomyopathic alterations (MiCM) or Purkinje (Purk) activities with structurally normal hearts.

Objectives: This study sought to evaluate the characteristics of recurrent VF recorded on implantable defibrillator electrograms, associated with these substrates.

Methods: This was a multicenter collaboration study.

Aims: Superior vena cava (SVC) isolation during atrial fibrillation catheter ablation is limited by the risk of collateral damage to the sinus node and/or the phrenic nerve. Due to its tissue-specificity, we hypothesized the feasibility and safety of pulsed-field ablation (PFA)-based SVC isolation.

Methods And Results: One hundred and five consecutive patients undergoing PFA-based AF catheter ablation were prospectively included.

Article Synopsis
  • The study examines the effectiveness of endocardial (ENDO) ablation in treating arrhythmogenic right ventricular cardiomyopathy (ARVC), specifically focusing on its long-term outcomes and factors influencing survival without ventricular tachycardia (VT).
  • A total of 74 patients with ARVC underwent ENDO-only VT ablation between 1998 and 2020, with about 66% achieving noninducibility of VT and a median follow-up of 6.6 years revealing that over 54% remained free of VT recurrence.
  • Important predictors for long-term VT-free survival included being over 45 years at diagnosis and achieving VT noninducibility, suggesting that ENDO-only ablation could be a viable initial

Article Synopsis
  • Epicardial access is important during ventricular tachycardia ablation, and the study compares two methods: traditional ConvEpi access and a newer method called EpiCO, which involves puncturing coronary venous branches.
  • The study included 153 patients and found that both methods had similar success rates, but ConvEpi was quicker and associated with more complications, especially significant bleeding.
  • Overall, EpiCO access showed a decrease in major complications and bleeding compared to ConvEpi, suggesting it might be a safer option for patients.

Article Synopsis
  • Predicting outcomes for patients receiving Left Ventricular Assist Devices (LVADs) is crucial, but current methods focusing on right ventricular function are lacking in prognostic value.
  • The study utilized data from the ASSIST-ICD registry to evaluate right ventriculoarterial coupling as a potential predictor of all-cause mortality upon LVAD implantation.
  • Findings showed that while some measures like TAPSE/sPAP and PAPi were not linked to long-term survival, the ratio of right atrial pressure to pulmonary capillary wedge pressure (RAP/PCWP) was significantly associated with increased mortality, maintaining its relevance even after adjusting for other risk factors.

Background: Electrocardiographic screening before subcutaneous implantable cardioverter-defibrillator (S-ICD) implantation is unsuccessful in around 10% of cases. A personalized screening method, by slightly moving the electrodes, to obtain a better R/T ratio has been described to overcome traditional screening failure.

Objective: The objectives of the SIS study were to assess to what extent a personalized screening method improves eligibility for S-ICD implantation and to evaluate the inappropriate shock rate after such screening success.

Background: Cryoballoon ablation is currently the gold standard technique for single-shot pulmonary vein isolation (PVI). Pulsed field ablation (PFA) has recently emerged as an interesting nonthermal alternative energy for PVI. The purpose of our study was to evaluate the safety and long-term efficacy of PVI using the pentaspline PFA catheter in comparison to cryoballoon ablation.

Article Synopsis
  • Pulmonary vein isolation (PVI) alone is often inadequate for treating persistent atrial fibrillation, and adding left atrial posterior wall (LAPW) ablation has had mixed results due to concerns about safety and effectiveness.
  • This study compares the safety and effectiveness of PVI combined with LAPW ablation versus PVI alone using pulsed-field ablation (PFA) in patients with persistent atrial fibrillation.
  • Results show no significant difference in freedom from arrhythmias or major adverse events between the two groups, indicating that adding LAPW ablation may not improve outcomes in this patient population.

Importance: Previous studies evaluating the association of patient sex with clinical outcomes using conventional thermal ablative modalities for atrial fibrillation (AF) such as radiofrequency or cryoablation are controversial due to mixed results. Pulsed field ablation (PFA) is a novel AF ablation energy modality that has demonstrated preferential myocardial tissue ablation with a unique safety profile.

Objective: To compare sex differences in patients undergoing PFA for AF in the Multinational Survey on the Methods, Efficacy, and Safety on the Postapproval Clinical Use of Pulsed Field Ablation (MANIFEST-PF) registry.
