Clinical Significance of Microembolic Signal Detection in Acute Ischemic Stroke: Insights Into Ongoing Cerebral Embolization and Occult Etiologies

European Journal of Neurology, Volume 33, Issue 3, March 2026.
In this prospective study of anterior circulation AIS patients, microembolic signals (MES) were detected in 16% of cases, absent in lacunar stroke. MES presence was linked to multiple‐territory infarcts, newly diagnosed atrial fibrillation, and cancer‐associated stroke.

First Report on Atrial Leadless Pacing in a Lateral Tunnel Fontan Patient

Journal of Cardiovascular Electrophysiology, Volume 37, Issue 3, Page 539-543, March 2026.
ABSTRACT Introduction No reports on atrial leadless pacing have been demonstrated in patients with the Fontan palliation. We present the case of a patient with a Lateral tunnel Fontan palliation with leadless pacing system for symptomatic bradycardia in the setting of sinus node dysfunction. Methods After internal review board approval, a retrospective

Bachmann's Bundle‐Related Atrial Tachycardias Following Catheter Ablation of Persistent Atrial Fibrillation

Journal of Cardiovascular Electrophysiology, Volume 37, Issue 3, Page 561-571, March 2026.
ABSTRACT Background Atrial tachycardias (AT) after radiofrequency ablation (RFA) of atrial fibrillation (AF) may utilize Bachmann's bundle (BB). Due to their epicardial location, these ATs remain poorly understood. Objective To describe the electrophysiologic and anatomic basis of BB‐related ATs.

Averaged Impedance Drop Estimates Conduction Gap During Pulmonary Vein Isolation in Atrial Fibrillation

Journal of Cardiovascular Electrophysiology, Volume 37, Issue 3, Page 501-509, March 2026.
ABSTRACT Background EnSite X provides a module to filter oscillated generator impedance signals due to cardiac beating/respiration (averaged impedance drop, AID). TactiFlex ablation catheter Sensor Enabled (TFSE) is the latest product to incorporate a contact‐force sensor with a flexible tip but without lesion‐estimating parameters.

Leadless Versus Transvenous Dual‐Chamber Pacemakers: Real‐World Evidence From AVEIR DR Coverage With Evidence Development Study

Journal of Cardiovascular Electrophysiology, Volume 37, Issue 3, Page 544-553, March 2026.
ABSTRACT Background AVEIR DR, an industry‐first dual‐chamber leadless pacemaker (LP), provides continuous atrioventricular synchrony through implant‐to‐implant (i2i) communication between atrial and ventricular LP devices. It is important to evaluate the early real‐world comparative safety of AVEIR DR LP.

Impact of Pulsed Field Ablation Dosing on Outcome After Pulmonary Vein Isolation Using a Pentaspline Ablation Catheter: A Prospective Comparison of 8 Versus 16 Applications

Journal of Cardiovascular Electrophysiology, Volume 37, Issue 3, Page 583-592, March 2026.
ABSTRACT Background Pulsed field ablation (PFA) is a novel, non‐thermal ablation modality to achieve pulmonary vein isolation (PVI) for the treatment of atrial fibrillation (AF). For the pentaspline catheter, eight applications per pulmonary vein (PV) are considered standard, with four in basket configuration and four in flower configuration.

Unusual Tachycardia Association In A patient Without Structural Heart Disease

Indian Pacing and Electrophysiology Journal, 2009
We report an unusual association of persistent atrial flutter and bundle branch re-entrant ventricular tachycardia in a young patient without structural heart disease. Atrial flutter masked the infra-Hisian conduction disease, was fundamentally dependent

Long‐Term Follow‐Up After Atrioventricular Node Ablation in Patients With Atrial Fibrillation: A Nationwide Danish Cohort Study

Journal of Cardiovascular Electrophysiology, Volume 37, Issue 3, Page 606-613, March 2026.
ABSTRACT Introduction Atrioventricular node (AVN) ablation after pacemaker implantation is a rate control option for patients with symptomatic atrial fibrillation (AF) when rhythm control with anti‐arrhythmic drug therapy and/or ablation with pulmonary vein isolation fails.

Empowered or Overwhelmed? Wearable Health Technologies and Consumer Well‐Being in the Context of Consumer–Physician Interactions

Journal of Consumer Affairs, Volume 60, Issue 1, Spring 2026.
ABSTRACT Wearable health technologies (WHTs) increasingly enable continuous, consumer‐driven health monitoring, yet healthcare systems remain organized around episodic, reactive care. This research examines how this misalignment shapes consumer well‐being by integrating consumer and physician perspectives on wearable‐generated data.
