Transthoracic three-dimensional echocardiography of tricuspid valve

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2017
Imaging of the tricuspid valve (TV) by three-dimensional echocardiography (3DE) has not received much attention. 3DE allows users to visualize the whole TV apparatus from any perspective and enables a comprehensive evaluation of the leaflets. This review

Three-dimensional echocardiography in congenital heart disease

Echo Research and Practice, 2019
Three-dimensional echocardiography is a valuable tool for the assessment of cardiac function where it permits calculation of chamber volume and function. The anatomy of valvar and septal structures can be presented in unique and intuitive ways to enhance

Three dimensional echocardiographic imaging of multiple recurrent myxomas

Monaldi Archives for Chest Disease, 2020
We report a case of a recurrence of 5 cardiac myxomas in both atria with atypical anatomical features difficult to image. Although a multimodality imaging was performed, three-dimensional echocardiography (3DE) was the only technique able to correctly ...

Real-time three dimensional transesophageal echocardiography: technical aspects and clinical applications

Heart International, 2010
Real-time three-dimensional transeso-phageal echocardiography (RT3DTEE) is now commonly used in daily clinical practice. The transesophageal, compared to the transthoracic approach, allows the visualization of the whole spectrum of the mitral valve ...

Three-dimensional fetal echocardiography

Progress in Biophysics and Molecular Biology, 1998
The complex anatomy and dynamics of the heart make it a challenging organ to image. The fetal heart is particularly difficult because it is located deep within the mother's abdomen and direct access to electrocardiographic information is difficult.

Raman Microscopy at the Organic–Inorganic Interfaces in Human Calcified Aortic Valves Shows the Co‐Existence of Whitlockite Crystals and Carbonated Hydroxyapatite‐Mineralized Collagen Fibrils

Advanced Functional Materials, EarlyView.
This study advances our understanding of aortic valve stenosis by capturing spatially resolved chemical and structural changes at the nanoscale. The findings highlight the potential of combined Raman and electron microscopy for understanding calcification mechanisms across diverse tissue types.

From Clinic to Computation: Multiscale Bioengineering Strategies for Durable Biological Aortic Valve Replacements

Advanced Functional Materials, EarlyView.
Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.
