Two-dimensional transthoracic echocardiography (2D TTE) and two-dimensional transesophageal echocardiography (2D TEE) are regarded as the main imaging techniques for the assessment of degenerative mitral valve regurgitation (DMVR). However, describing the complex morphology of DMVR with 2D TTE and 2D TEE remains at the very least challenging. Three-dimensional (3D) TEE is an ideal technique for illustrating the extremely variable morphology of DMVR, providing images of unparalleled quality in terms of anatomical detail.

- Right ventricular free-wall strain is a potential key diagnostic indicator in patients with transthyretin cardiac amyloidosis (ATTR-CA), which affects all parts of the heart.
- In a study involving 108 ATTR-CA patients and 106 controls, this strain measurement was shown to be independently linked to the diagnosis of ATTR-CA when combined with other echocardiographic parameters.
- Furthermore, a right ventricular free-wall strain of -16% or less was associated with a threefold increased risk of major cardiovascular and cerebrovascular events, highlighting its importance for risk assessment in these patients.
Vision provides animals with detailed information about their surroundings, conveying diverse features such as color, form, and movement across the visual scene. Computing these parallel spatial features requires a large and diverse network of neurons, such that in animals as distant as flies and humans, visual regions comprise half the brain's volume. These visual brain regions often reveal remarkable structure-function relationships, with neurons organized along spatial maps with shapes that directly relate to their roles in visual processing.
