Comparison of Pentaspline Pulsed Field Ablation Catheter Mapping Modes to Assess Pulmonary Vein Isolation for Paroxysmal Atrial Fibrillation

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
Pentaspline mapping in pulsed field AF ablation. ABSTRACT Background We assessed the electro‐anatomic mapping (EAM) capabilities of a pulsed field ablation (PFA) system previously guided by fluoroscopy to assess acquisition modes, and effects of near and far‐field signal.

The V6R/V4R Index: A Novel ECG Parameter for Identifying Idiopathic Ventricular Arrhythmias Originating From the Aortic Cusp

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
The V6R/V4R amplitude index is a novel and practical electrocardiographic parameter for identifying idiopathic ventricular arrhythmias originating from the aortic cusp. A cutoff >0.55 accurately distinguishes cusp from adjacent non‐cusp origins within the left ventricular outflow tract, facilitating targeted mapping and procedural planning.

Safety and Utility of Smartphone‐Based Heart Monitors in Pediatric Patients With Cardiovascular Implantable Electronic Devices

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
Smartphone heart monitors in pediatric CIEDs: A pilot study. Smartphone heart monitors did not induce EMI in children with CIEDs, enabling reliable heart rate measurement and accurate identification of ventricular non‐captures. ABSTRACT Background Portable heart monitors enable on‐demand electrocardiogram (ECG) recordings and enhance symptom‐rhythm ...

Dynamic Behavior of Left Atrial Low‐Voltage Areas in Persistent Atrial Fibrillation: Implications for Substrate‐Guided Ablation

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
Patient selection and analysis flow diagram. The exact pre‐inclusion denominator and reliable reason‐specific exclusion counts could not be reconstructed because a prospectively maintained screening log was unavailable. The diagram summarizes the final study cohort and analysis‐specific sample sizes. AF, atrial fibrillation; LVA, low‐voltage area; SR1,

Ventricular Tachycardia Ablation in Structural Heart Disease With LVEF > 35%: Clinical Outcomes and Recurrence Patterns

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background In patients with structural heart disease (SHD) and moderately impaired left ventricular ejection fraction (LVEF > 35%), data on outcomes after ventricular tachycardia (VT) ablation remain limited. This analysis focuses on VT recurrence after ablation in patients presenting with sustained VT and LVEF > 35% within a secondary ...

Neurotrophic extracellular matrix proteins promote neuronal and iPSC astrocyte progenitor cell‐ and nano‐scale process extension for neural repair applications

open access: yesJournal of Anatomy, Volume 246, Issue 4, Page 585-601, April 2025.
The extracellular matrix plays a critical role in modulating cell behaviour in the central nervous system influencing neural cell morphology and growth. However, a better understanding of the impact of individual matrix proteins on both neurons and astrocytes is critical for advancing the development of matrix‐based neural repair strategies.

When Great Powers Struggle: How Geopolitical Alignments of Small States Are Influenced by Their MNEs

open access: yesJournal of Management Studies, EarlyView.
Abstract Comparing two distinct deglobalization periods, this study shows how Finnish multinational enterprises (MNEs) used corporate diplomatic activities (CDA) to influence Finland's alignment with a struggling great power. Drawing from hegemonic stability theory and new institutional economics, we argue that the power's collapsing global networks ...
