Cerebral oxygen extraction fraction as a physiological biomarker in vascular cognitive impairment: A study in older adults enriched for small vessel diseases

Alzheimer's &Dementia, Volume 22, Issue 9, September 2026.
Abstract INTRODUCTION Vascular cognitive impairment and dementia (VCID) is a common cause of cognitive impairment, yet validated biomarkers, particularly those reflecting vascular function, remain lacking. Oxygen extraction fraction (OEF), which reflects the functional status of cerebral small vessels, is a potential physiological biomarker for VCID ...

Atomically precise metal cluster enzymes for pathological tissue regeneration

BMEMat, Volume 4, Issue 3, September 2026.
Schematic illustration of atomically precise metal cluster enzymes (MCEs) for pathological tissue regeneration. Atomically precise MCEs can modulate biological processes, such as attenuation of inflammatory responses, eradication of bacterial pathogens, regulation of angiogenesis, and promotion of cell development.

The Impact of a Visualized Steerable Sheath on Radiofrequency Catheter Ablation for First‐Time Atrial Fibrillation Ablation: A Prospective, Randomized, Single‐Blind Study

Catheterization and Cardiovascular Interventions, Volume 108, Issue 3, Page 924-934, September 1, 2026.
ABSTRACT Background A 3D electroanatomical mapping (3D‐EAM) visualized steerable sheath was designed to improve catheter placement and reduce radiation exposure during ablation, an established treatment for atrial fibrillation (AF). However, prospective randomized data comparing the procedural and clinical outcomes of visualized and non‐visualized ...

A Randomized Controlled Trial Comparing the TruSteer and FXD Double Curve Delivery Systems for Left Atrial Appendage Occlusion With the Watchman FLX Pro Device—The GUIDE‐LAAO Study

Catheterization and Cardiovascular Interventions, Volume 108, Issue 3, Page 899-907, September 1, 2026.
ABSTRACT Background Deflectable delivery systems have been introduced to enhance coaxial alignment and procedural efficacy during left atrial appendage occlusion (LAAO), yet randomized comparisons with conventional fixed‐curve systems are lacking. Aims The GUIDE‐LAAO trial evaluated whether the TruSteer deflectable delivery system is non‐inferior to ...

The High‐Sensitivity C‐Reactive Protein−Albumin−Lymphocyte Index Is a Prognostic Marker for All‐Cause and Cardiovascular Mortality in Patients With ST‐Elevation Myocardial Infarction

Catheterization and Cardiovascular Interventions, Volume 108, Issue 3, Page 1034-1046, September 1, 2026.
ABSTRACT Background Inflammation and immune dysfunction may worsen the prognosis of patients with ST‐segment elevation myocardial infarction (STEMI). Aims This study aimed to assess whether the high‐sensitivity C‐reactive protein–albumin–lymphocyte index (hsCALLYI) could be used to predict the prognosis of STEMI patients who received emergency ...

Catheter Thrombectomy of Massive Pulmonary Embolism Secondary to Spongostan Embolisation: A Case Report

Catheterization and Cardiovascular Interventions, Volume 108, Issue 3, Page 1029-1033, September 1, 2026.
ABSTRACT Novel adjuvant hemostatic agents are increasingly used in surgical procedures to achieve hemostasis. We present a case of embolisation of hemostatic agents during a neurosurgical operation, causing massive PE requiring venoarterial extracorporeal membrane oxygenation support, in a 7‐year‐old boy.

Congenital Absence of the Left Pulmonary Artery Associated With Right‐Sided Aortic Arch Presenting as Hemoptysis in an Adult: A Case Report

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Congenital unilateral absence of the pulmonary artery is a rare vascular anomaly that may remain undiagnosed until adulthood. Patients can present with unexplained hemoptysis, recurrent respiratory infections, or pulmonary hypertension. Contrast‐enhanced CT plays a crucial role in diagnosis, evaluation of collateral circulation, and guiding ...
