Diastolic Dysfunction With Preserved Ejection Fraction After the Fontan Procedure

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022
Background Heart failure phenotyping in single‐ventricle Fontan patients is challenging, particularly in patients with normal ejection fraction (EF). The objective of this study was to identify Fontan patients with abnormal diastolic function, who are ...

Significance of the pericardium in human subjects: Effects on left ventricular volume, pressure and ejection [PDF]

, 1985
To assess the effect of the pericardium, left ventricular systolic function and diastolic compliance were studied in 15 patients before and after pericardiotomy during coronary artery surgery.

Diastolic Function Gets Personal

JACC: Cardiovascular Imaging, 2019
![Figure][1] ![Figure][1] Exertional dyspnea is one of the most common symptoms in cardiology, and thus is also a major indication for cardiac imaging. Diastolic ventricular dysfunction is often a prime suspect for a cardiac etiology of exertional dyspnea.

Grading diastolic left ventricular function [PDF]

European Journal of Heart Failure, 2011
This editorial refers to ‘Diagnosis of heart failure with pre-served ejection fraction: which parameters and diagnosticstrategies are more valuable?’, by X.-X. Shuai et al.,published in this issue on page 737–745.The diagnosis of heart failure (HF) is based on symptoms and signsof HF, as well as evidence for a functional or structural abnormalityof the

Biologically‐Inspired Melt Electrowriting for the Generation of Highly Biomimetic Functional Myocardium

Advanced Functional Materials, EarlyView.
In this work, melt electrowriting is used to fabricate a 3D printed scaffold design that generates engineered cardiac tissues with in‐plane contraction, mimicking natural myocardium. It is shown that these tissues display advanced maturation and functionality.

Diastolic Cardiac Function by MRI—Imaging Capabilities and Clinical Applications

Tomography, 2021
Most cardiac studies focus on evaluating left ventricular (LV) systolic function. However, the assessment of diastolic cardiac function is becoming more appreciated, especially with the increasing prevalence of pathologies associated with diastolic ...

Towards Fully Automated Segmentation of Rat Cardiac MRI by Leveraging Deep Learning Frameworks [PDF]

arXiv, 2021
Automated segmentation of human cardiac magnetic resonance datasets has been steadily improving during recent years. However, these methods are not directly applicable in preclinical context due to limited datasets and lower image resolution. Successful application of deep architectures for rat cardiac segmentation, although of critical importance for ...

Shape‐Reconfigurable Crack‐Based Strain Sensor with Ultrahigh and Tunable Sensitivity

Advanced Functional Materials, EarlyView.
A highly sensitive crack‐based sensor with tunable strain detection capabilities is demonstrated through controlled nanocrack formation in a line‐patterned shape memory polymer substrate. The sensor design integrates thermoplastic polyurethane and poly(lactic acid), enabling thermo‐responsive reconfiguration of crack geometry.

Serum cystatin C as a biomarker of cardiac diastolic dysfunction in patients with cardiac disease and preserved ejection fraction [PDF]

, 2013
Diastolic dysfunction of the heart is correlated with cardiac mortality. Serum cystatin C (CysC) is an endogenous marker of kidney function. It is not clear whether serum CysC is associated with diastolic dysfunction in patients with varying cardiac ...

Narrowband Detection via Charge Collection Narrowing Organic Photodetector Enabled by Low Bandgap Random Terpolymer for Biometric Sensing

Advanced Functional Materials, EarlyView.
A novel low‐bandgap random terpolymer is designed for narrow band detection in charge collection narrowing (CCN) based organic photodetectors. With a relative thin active layer (<1 µm), the CCN‐based devices achieved a narrowband response of 68 nm full‐width‐at‐half‐maximum at 916 nm, together with Responsivity values of 0.13 A W−1 and dark current of ...
