High-density mapping of his-ventricular intervals: impact of recording site and sex-specific differences

Accurate assessment of the His–ventricular (HV) interval is essential to diagnosing infranodal conduction disease, but the influence of recording site and sex on HV values is not well defined. To evaluate the impact of measurement location and sex on HV interval values using high-density (HD) mapping catheters in patie...

Impact of differences in kidney function estimation by creatinine compared to cystatin C on clinical outcomes in patients with atrial fibrillation

Abstract Aims Differences between cystatin C-based and creatinine-based glomerular filtration rate estimations (eGFRdiff) have been associated with adverse outcomes. We aimed to investigate the prevalence of eGFRdiff and its association with clinical outcomes and brain lesions in patients with atrial fibrillation (AF)....

Pulmonary Vein Isolation Using Pulsed Field Ablation With vs Without Posterior Wall Isolation in Patients With Symptomatic Persistent Atrial Fibrillation: The PIFPAF-PFA Randomized Clinical Trial.

In patients with persistent AF, adding PFA-based PWI to PVI did not significantly reduce atrial tachyarrhythmia recurrence lasting 30 seconds or longer compared with PVI alone, and the findings for secondary end points are hypothesis generating and warrant further evaluation in a larger trial.

Left atrial anatomy and atrial arrhythmia recurrence after pulsed-field ablation.

BACKGROUND The impact of left atrial (LA) anatomical features on atrial arrhythmia (AA) recurrence after pulsed-field (PF)-based pulmonary vein isolation (PVI) is unknown. This study aimed to assess LA anatomical features associated with long-term AA recurrence after PVI. METHODS We prospectively enrolled patients un...

Safety and Efficacy of Left Atrial Ablation After Percutaneous Left Atrial Appendage Occlusion in High-Bleeding-Risk Patients with Atrial Fibrillation: A Multicenter Analysis from the PROCEED-AF Ablation Registry.

BACKGROUND AND AIMS Patients with left atrial appendage (LAAO) devices are increasingly referred for AF ablation, yet anticoagulation strategies remain uncertain. The goal of this study was to evaluate the safety and efficacy of catheter ablation for atrial fibrillation (AF) in patients with pre-existing LAAO devices a...

Undetected Heart Failure in Cardiology: Prevalence, Characteristics, and Outcome.

One-out-of three patients referred for CAD work-up had undetected HF, which was associated with cardiovascular death and AHF hospitalization, and was associated with an increased cumulative incidence of the composite endpoint.
