Echocardiography derived three-dimensional printing of normal and abnormal mitral annuli

Annals of Cardiac Anaesthesia, 2014
Aims and Objectives: The objective of this study was to assess the clinical feasibility of using echocardiographic data to generate three-dimensional models of normal and pathologic mitral valve annuli before and after repair procedures.

Clinical Insights From a Case of Sifrim‐Hitz‐Weiss Syndrome With a CHD4 Variant: Expanding the Phenotypic Spectrum and Its Response to Growth Hormone Therapy

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT To enhance clinicians' understanding of Sifrim‐Hitz‐Weiss syndrome (SIHIWES), this study investigated the clinical phenotypes, genetic characteristics, and response to growth hormone therapy in a patient. A case of a patient with global developmental delay and distinctive facial features is presented.

Isovolumic relaxation strain imaging is an accurate and sensitive approach for detection of active diastolic dysfunction: A preclinical study

Animal Models and Experimental Medicine, EarlyView.
A modified approach was developed to accurately identify the isovolumetric relaxation time (IVRT) using an apical three‐chamber view. Compared with conventional echocardiography, isovolumic relaxation strain imaging (IVSI) helps to detect the earlier alternations of diastolic function in transverse aortic constriction (TAC) mice.

Predictors of worsening TR severity after right ventricular lead placement: any added value by post-procedural fluoroscopy versus three –dimensional echocardiography?

Cardiovascular Ultrasound, 2021
Background The effect of right ventricular (RV) leads on tricuspid valve has been already raised concerns, especially in terms of prognostic implication.

The characteristics of collagen‐induced rheumatoid arthritis in macaques and the changes of heart

Animal Models and Experimental Medicine, EarlyView.
The disease progression in CIA macaques was categorized into three stages: IIR (days 14–34): The indicators related to rheumatoid arthritis and the levels of immunoglobulin were all elevated. There was a small amount of joint effusion, edema and mild synovial hyperplasia. No joint swelling was observed by naked eye.

TWEAK/Fn14 signaling drives oxidative cardiac injury in systemic lupus erythematosus: Evidence from patient biomarker studies, lupus mouse models, and cardiomyocyte assays

Arthritis &Rheumatology, Accepted Article.
Objective Cardiac involvement is a major cause of morbidity in systemic lupus erythematosus (SLE). Tumor necrosis factor–like weak inducer of apoptosis (TWEAK) is elevated in SLE, but its contribution to lupus‐associated cardiac injury is unclear. We investigated the role of TWEAK/Fn14 signaling in SLE‐related cardiomyopathy and its potential as a ...

Left ventricular synchrony assessment: a comparative analysis using real time three-dimensional echocardiography and tissue Doppler imaging [PDF]

Einstein (São Paulo), 2007
Objective: Left ventricular regional synchrony can be analyzed bythree-dimensional echocardiography (3D Echo) as well as by tissueDoppler imaging (TDI). The aim of the study was to compare leftventricular synchrony assessment by both methods.
