Durability of Pulmonary Vein Isolation Using Pulsed-Field Ablation: Results From the Multicenter EU-PORIA Registry. [PDF]

BACKGROUND Pulsed-field ablation (PFA) is a novel nonthermal ablation technology with high procedural safety and efficiency for pulmonary vein isolation (PVI). Premarket data showed high PVI durability during mandatory remapping studies.

Impact of atrial rhythm on pulmonary vein signals in cryoballoon ablation – Sinus rhythm predicts real-time observation of pulmonary vein isolation

International Journal of Cardiology: Heart & Vasculature, 2019
Purpose: Real-time observation of pulmonary vein (PV) potentials with a spiral mapping catheter has emerged as a key electrogram-based procedural parameter to estimate lesion quality and titrate cryoenergy application during PV isolation (PVI) with the ...

Retinal Vessel Segmentation: A Comprehensive Review From Classical Methods to Deep Learning Advances (1982–2025)

Advanced Intelligent Systems, EarlyView.
Four decades of retinal vessel segmentation research (1982–2025) are synthesized, spanning classical image processing, machine learning, and deep learning paradigms. A meta‐analysis of 428 studies establishes a unified taxonomy and highlights performance trends, generalization capabilities, and clinical relevance.

Pathogenic PF4/Polyanion ELISA‐Negative Antibodies in HIT

American Journal of Hematology, EarlyView.
ABSTRACT Background Platelet factor 4‐polyanion enzyme‐linked immunosorbent assays (ELISAs) are considered highly sensitive for diagnosing heparin‐induced thrombocytopenia (HIT), such that current practice guidelines recommend use of ELISA‐negative results to exclude HIT.

Co‐Occurring Non‐Cardiac Congenital Anomalies Among Cases With Congenital Heart Defects

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Cases with congenital heart defects (CHD) often have other associated anomalies. The aim of this investigation was to assess the prevalence and the types of co‐occurring anomalies in CHD in a well‐defined population. The anomalies co‐occurring with CHD were ascertained in all live births, stillbirths and terminations of pregnancy for fetal ...

Evolution of post–pulmonary vein isolation atrial fibrillation inducibility at redo ablation: Electrophysiological evidence of extra–pulmonary vein substrate progression

, 2019
The goals of this study were to study the evolution of post–pulmonary vein isolation (PVI) AF inducibility (AFI) after AF ablation and to compare patients with organized atrial tachycardia recurrence (OATr) versus those with paroxysmal or persistent AF ...

Recent advances in the construction of humanized animal models and applications in translational medicine

Animal Models and Experimental Medicine, EarlyView.
Substantial advances have been achieved in the development of humanized mouse models, which have proven highly valuable in evaluating cancer immunotherapies and elucidating the mechanisms of infectious diseases. There is now a growing shift in research toward larger animal models—such as pigs—that offer greater physiological similarity to humans ...
