Pulsed-field vs. Cryoballoon vs. Radiofrequency ablation: outcomes after pulmonary vein isolation in patients with persistent atrial fibrillation
Pulsed-field ablation (PFA) has shown promising data in terms of safety and procedural efficiency for pulmonary vein isolation (PVI), with similar long-term outcomes compared to radiofrequency ablation (RFA) and cryoballoon ablation (CBA) in patient with paroxysmal atrial fibrillation (AF) (Source: Heart Rhythm)

Acute Kidney Injury after Catheter Ablation of Atrial Fibrillation: Comparison between Different Energy Sources
Pulsed field ablation (PFA) is an innovative technology recently adopted for treating atrial fibrillation (AF). Preclinical and clinical studies have reported a reassuring safety profile because of its tissue-specific effect, sparing adjacent tissues.1 However, two cases of acute kidney injury (AKI) secondary to hemolysis after PFA have recently been reported after an uncommonly high number of applications.2,3 Similarly, a subsequent pilot study reported the occurrence of AKI in 4/28 patients after PFA for AF.

Left bundle branch block-induced cardiomyopathy: a distinctive form of cardiomyopathy that might require a dedicated form of treatment.
The His-Purkinje system is the ventricular component of the cardiac conduction system that orchestrates the electrical impulse propagation which underlies every contraction of the heart. It originates from the AV-node and runs down to the interventricular septum and subdivides into the left and right bundle branches. These major branches divide further and spread diffusely along the sub endocardium. [1],[2] Damage in one of those branches may result in impaired electrical conduction. (Source: Heart Rhythm)

Feasibility and efficacy of real-time ultrasound-guided venous closure with suture-mediated vascular closure device
Complications of venous vascular access are usually non-fatal but are the most common complications after transvenous catheter intervention. Vascular closure devices (VCD) have recently become available for venous closure. (Source: Heart Rhythm)

Relationship between wait-times and post-atrial fibrillation ablation outcomes: a population based study
Rhythm control is a cornerstone of atrial fibrillation (AF) management. Shorter time between diagnosis of AF and receipt of catheter ablation is associated with greater rates of therapy success. Prior work considered diagnosis-to-ablation time as a binary or categorical variable and did not consider the unique risk profile of patients once a referral for ablation is made.

Regional Differences in the Outcomes of Catheter Ablation for Atrial Fibrillation in the United States
We examined such variations by analyzing procedural complications and in-hospital outcomes among patients undergoing AF ablation utilizing the National Inpatient Sample (NIS), a collaborative effort between federal, state, and industry stakeholders sponsored by the Agency for Healthcare Research and Quality (AHRQ), captures hospital data from over 7 million discharges annually, representing approximately 20% of nonfederal hospital discharges across all 50 states (1).

Atrioventricular Optimization Improves Cardiac Resynchronization Response in Patients with Long Interventricular Electrical Delays: A Pooled Analysis of the SMART-AV and SMART-CRT Trials
The utility of atrioventricular (AV) optimization (AVO) algorithms remains in question. A substudy of the SMART-AV trial found patients with prolonged interventricular (RV-LV) delays ≥70 ms were more likely to benefit from CRT with AVO. The SMART-CRT trial evaluated AVO based on these results, but the study was underpowered. (Source: Heart Rhythm)

Reduced dementia risk in patients with optimized anticoagulation therapy undergoing atrial fibrillation ablation
Atrial fibrillation (AF) is associated with the development of dementia and observational studies have shown that oral anticoagulation (OAC) and catheter ablation reduce dementia risk. However, such studies did not consistently report on periprocedural anticoagulation and long term OAC coverage, for which reason the separate effect of AF ablation on dementia risk could not be established.
