Contrast ‑ in cardiac magnetic resonance imaging [PDF]

Echocardiography, 2018
The utility and role of cardiac magnetic resonance (CMR) as a non‐invasive diagnostic imaging modality has been well recognized in the field of cardiovascular disease. Use of late gadolinium enhancement (LGE) has further enhanced CMR's ability to determine structural, functional, and prognostic information in various cardiovascular diseases.

Cellular Responses to Mechanical Cues Across Scales: From Fundamental Insights to Translational Potential

Advanced Healthcare Materials, EarlyView.
This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...

Applications of Cardiac Magnetic Resonance in Electrophysiology [PDF]

Circulation: Arrhythmia and Electrophysiology, 2009
Because of its wide availability, echocardiography is the most frequently used modality for diagnosis of the underlying substrate for cardiac arrhythmia. However, echocardiography is unable to visualize intramyocardial substrates for reentrant arrhythmia such as fat or scar fibrosis.

The Different Facets of Myocarditis by Cardiac Magnetic Resonance Imaging

Heart Views
Myocarditis is an inflammatory condition affecting the myocardium and may have different etiologies. Patients usually present with chest pain and elevated levels of cardiac enzymes, mainly troponin. Cardiac magnetic resonance (CMR) imaging has emerged as

On T2* Magnetic Resonance and Cardiac Iron [PDF]

Circulation, 2011
Background— Measurement of myocardial iron is key to the clinical management of patients at risk of siderotic cardiomyopathy. The cardiovascular magnetic resonance relaxation parameter R2* (assessed clinically via its reciprocal, T2*) measured in the ventricular septum is used to assess cardiac iron, but iron ...

Abnormal elevation of myocardial necrosis biomarkers after coronary artery bypass grafting without established myocardial infarction assessed by cardiac magnetic resonance

Journal of Cardiothoracic Surgery, 2017
Background The diagnosis of peri-procedural myocardial infarction is complex, especially after the emergence of high-sensitivity markers of myocardial necrosis. Methods In this study, patients with normal baseline cardiac biomarkers and formal indication

A Geometrically Transient Platform for Bioelectronic Implants

Advanced Materials, EarlyView.
Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.
