Multiwavelength Implantable Oximeter for Wireless Monitoring of Tissue Oxygenation in the Presence of Blood Volume Changes

Advanced Healthcare Materials, Volume 15, Issue 35, 18 September 2026.
This study presents an implantable, wireless, battery‐free oximeter that can continuously monitor physiologically consistent regional tissue oxygenation under dynamic changes of blood volume. This is achieved through multiwavelength photoplethysmography and validated both via Monte Carlo simulations and in vivo rat studies. Different stress events were

Same‐Day Discharge After Transcatheter Aortic Valve Implantation: Who, When, and How?

Catheterization and Cardiovascular Interventions, Volume 108, Issue 3, Page 816-823, September 1, 2026.
ABSTRACT The burden of severe aortic stenosis requiring treatment is growing due to ageing populations. This places increased demands on health resources due to the growing number of transcatheter aortic valve implantation (TAVI) procedures and hospital bed occupancy.

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 ...

Long‐Term Outcome After Pulsed Field Ablation for Atrial Fibrillation Across an Atrial Septal Defect Closure Device: A 20‐Month Follow‐Up Case Report

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Balloon‐assisted transseptal puncture across a large atrial septal defect closure device can permit pulsed‐field ablation in selected patients with complex septal anatomy, achieving durable pulmonary vein isolation and sinus rhythm. A borderline residual left‐to‐right shunt developed post‐procedure but decreased on serial imaging without ...

Association of Transition Zone Burden With Recurrence in Elderly Patients With Paroxysmal Atrial Fibrillation Without Low‐Voltage Areas

Clinical Cardiology, Volume 49, Issue 9, September 2026.
Transition zone (TZ) is defined as regions with bipolar voltage between 0.5 and 1 mV in left atrium. In 158 elderly PAF patients without low‐voltage areas (LVA), TZ burden is associated with reduced left atrial conduction velocity (LACV) and independently predicts atrial tachyarrhythmia (ATA) recurrence following CPVI.

Safety and Efficacy of Pulsed‐Field Ablation With a Pentaspline Ablation Catheter Versus Cryoablation for Atrial Fibrillation: A Systematic Review and Meta‐Analysis

Clinical Cardiology, Volume 49, Issue 9, September 2026.
This meta‐analysis compared pentaspline PFA and cryoballoon ablation for AF. PFA shortened procedure time, reduced phrenic nerve injury, and lowered arrhythmia recurrence in paroxysmal AF despite elevated troponin release. ABSTRACT Background Pulsed‐field ablation (PFA) is an emerging technology for atrial fibrillation (AF) ablation.
