Free‐Breathing, 3D Cardiac Magnetic Resonance Elastography for Myocardial Stiffness Mapping

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2356-2369, April 2026.
ABSTRACT Purpose Magnetic resonance elastography (MRE) of the heart has predominantly utilized breath‐held acquisitions with limited anatomic coverage. This work investigates the feasibility of 3D, free‐breathing cardiac MRE. Methods A 3D hybrid radial and EPI acquisition is utilized and combined with retrospective binning of k‐space via physiologic ...

Reducing Respiratory Artifacts in Heart Rate Variability during Functional Food Intake Using ECG‐Derived Respiration

IEEJ Transactions on Electrical and Electronic Engineering, Volume 21, Issue 3, Page 413-420, March 2026.
Heart rate variability (HRV) has been analyzed to assess the effects of food on autonomic nervous activity, but HRV is reportedly influenced by respiration. Reducing respiratory artifacts in HRV analysis requires respiratory signals. In this study, we estimated respiratory signals from electrocardiogram (ECG), compared these signals with actual ...

Reproducibility and agreement of pulse wave velocity and augmentation index over repeated assessments using two different devices in adolescents

Clinical Physiology and Functional Imaging, Volume 46, Issue 2, March 2026.
Abstract Objectives We investigated the agreement between pulse wave velocity (PWV) and augmentation index (AIx%) obtained in a controlled fasted condition versus a non‐fasted, uncontrolled, “real‐world” condition. Thereafter, we assessed the reproducibility of PWV and AIx% over three repeated visits under controlled fasted conditions.

Cardiac Resynchronization Therapy: Reconsidering Its Essence as a Treatment for Electrical Dyssynchrony in Heart Failure

Journal of Arrhythmia, Volume 42, Issue 1, February 2026.
Flow of cardiac resynchronization therapy (CRT) in heart failure management. Heart failure (HF) patients with electrical dyssynchrony are first identified through screening. If electrical dyssynchrony contributes to HF deterioration, CRT is initiated to improve electrical synchrony.

Ablation of Ventricular Tachycardia Using the QDOT MICRO Ablation Catheter (VT‐MICRO Study)

Journal of Arrhythmia, Volume 42, Issue 1, February 2026.
Catheter ablation is useful to treat patients with ventricular tachycardia. QDOT Micro catheter is a next generation catheter designed to provide more efficient lesion creation with an accurate myocardial substrate analysis. Microelectrode mapping allows detection of higher voltage electrograms compared to standard bipolar mapping and Pentaray mapping.
