Advanced Science, EarlyView.Engineered heart tissues (EHTs) derived from human iPSCs replicate mechanisms of ventricular tachycardia at the tissue level. Acquired Long‐QT conditions cause early afterdepolarizations, wavebreak, and transient rotors; in contrast, focal cryoinjury forms a stable substrate that supports ongoing reentry.

Scaffold‐Free Living Cellular Structure With Omnidirectional Architectures
Advanced NanoBiomed Research, EarlyView.Hydrogel lumen confinement enables the direct formation of mechanically stable, scaffold‐free cellular filaments under entirely aqueous, phototoxicity‐free conditions. These processable living building blocks support omnidirectional assembly into complex three‐dimensional architectures, providing a simple and versatile platform for scaffold‐free ...

Noninvasive electrocardiographic imaging of chronic myocardial infarct scar [PDF]
Journal of Electrocardiology, 2015 Myocardial infarction (MI) scar constitutes a substrate for ventricular tachycardia (VT), and an accurate delineation of infarct scar may help to identify reentrant circuits and thus facilitate catheter ablation. One of the recent advancements in characterization of a VT substrate is its volumetric delineation within the ventricular wall by noninvasive

Myocardial Scar Imaging: Viability Beyond REVIVED [PDF]
Purpose of Review: It was previously believed that the presence of myocardial viability in patients with significant coronary artery disease improved outcomes following revascularisation, but the landmark STITCH trial found no significant correlation ...

Fragmented QRS – Its significance
Indian Pacing and Electrophysiology Journal, 2020 Fragment QRS (fQRS) complex is a myocardial conduction abnormality that indicates myocardial scar. It is defined as additional notches in the QRS complex. Though initially fQRS was defined in the setting of normal QRS duration (

Human Fibroblast–Myeloid Cell Tissue Atlas Across the Lungs, Synovium, Skin, and Heart
Arthritis &Rheumatology, EarlyView.Objective The availability of single‐cell RNA sequencing (scRNAseq) data in different tissues and disease states provides an opportunity to compare cellular subsets and identify common and unique cellular activation. In this study, we aimed to characterize shared and tissue‐specific myeloid and stromal phenotypes and to uncover key cellular subtypes ...
