Risk Stratification for the Occurrence of Ventricular Fibrillation in Patients with Early Repolarization Syndrome
Several signs of malignant early repolarizations (ERs) have been proposed in patients with ER syndrome (ERS). However, recent reports have challenged the efficacy of these signs in predicting future ventricular fibrillation (VF) in patients with ERS. (Source: Heart Rhythm)

Atrial Fibrillation and Heart Failure: to build a CASTLE you need a solid foundation
The authors claim that their score identifies heart failure (HF) patients who benefit the most from atrial fibrillation (AF) ablation. However, the crude hazard ratio (HR) for the primary endpoint was 0.32 in favour of ablation in the “high-risk group” and 0.41 in the “low-risk group”. Thus, AF ablation appears to perform equally well in both groups, but the higher number of events makes this different statistically significant only in the high-risk group. More than identifying patients who benefit from the ablation, the score seems to identify patients who will have worse outcomes, irrespective of the treatment st...

Author's reply to Atrial Fibrillation and Heart Failure: to build a CASTLE you need a solid foundation
To fully understand the predictive value of the CASTLE-HTx risk-score in relation to the benefits of catheter ablation in patients with end-stage heart failure (HF) and atrial fibrillation (AF), it is essential to distinguish between absolute and relative risk reduction. The observed hazard ratios (HR) favoring ablation of 0.32 and 0.41 for high-risk and low-risk patients, respectively, did not differ substantially on a relative scale. On an absolute scale, the incidence rate difference with ablation observed in high-risk patients (24.69/100 patient years) was significantly greater than that observed in low-risk patients (...

Fine-tuning early rhythm control strategies for atrial fibrillation – Timing matters to stay in sync
Rhythm control with either medications or catheter ablation is an established strategy for symptomatic patients with atrial fibrillation (AF), by reducing arrhythmic burden and improving patient quality of life, as well as reducing the risk of heart failure hospitalization and mortality in select populations with concomitant AF and heart failure. The 2023 ACC/AHA/ACCP/HRS guideline on AF management also underscores the role for early rhythm control in patients with recent AF diagnosis ( (Source: Heart Rhythm)

Lb-469807-01 impact of vigorous exercise in the long qt syndrome by genotype, age, and sex: data from the lifestyle and exercise in long qt syndrome registry (live-lqts)
In the multinational, NIH-funded, LIVE-LQTS, ventricular arrhythmia (VA) event rate was low in participants engaged in vigorous exercise and in the less active, in a largely appropriately-treated cohort. Genotype, age, and sex impact risk in LQTS, and triggers of VA differ. This analysis assesses if habitual vigorous exercise impacts VA risk and triggers differently, based on these features.

ARTESiA showed that apixaban, compared to aspirin, significantly reduced stroke or systemic embolism (SE) but increased major bleeding in patients with subclinical atrial fibrillation (SCAF). To better inform benefit-to-risk decision-making for the use of apixaban, we evaluated the benefits and hazards of apixaban according to baseline CHA2DS2-VASc score. (Source: Heart Rhythm)

Lb-469807-05 outcomes with and without oral anticoagulation in patients with prior stroke and device-detected atrial fibrillation: the noah-afnet 6 trial
Patients with a prior stroke are at high risk of recurrent strokes. In patients with ECG-documented atrial fibrillation (AF), anticoagulation reduces subsequent strokes. Detection of short and rare episodes of atrial fibrillation using implanted devices (device-detected AF, DDAF) is common in patients with a prior stroke and these patients are often treated with an anticoagulant when DDAF is detected. Data on the effectiveness and safety of oral anticoagulation in patients a prior stroke and DDAF but no ECG-documented AF are lacking. (Source: Heart Rhythm)

Lb-469809-02 impact of pulsed field vs thermal ablation on one-year atrial arrhythmia burden – sub-analysis of the advent trial
ADVENT revealed no significant difference in 1-year freedom from atrial arrhythmias (AA) between thermal and pulsed field ablation (PFA). However, recent studies indicate that the post-ablation AA burden is a better predictor of clinical outcomes than the dichotomous endpoint of 30-sec AA recurrence. Herein, we studied the impact of post-ablation AA burden on outcomes, and the effect of ablation modality on AA burden in ADVENT. (Source: Heart Rhythm)

The impact of contemporary techniques and technologies to optimize ablation delivery, reduce fluoroscopy use, and improve clinical outcomes using radiofrequency catheter ablation (RF-CA) for paroxysmal atrial fibrillation (PAF) has not been assessed in systematic, large, prospective, multicenter registries.
