Key result
Shear wave elastography is a promising non-invasive technique for estimating myocardial stiffness, offering potential diagnostic value for cardiomyopathies like amyloidosis and hypertrophic cardiomyopathy.
Why the study?
Assessing left ventricle diastolic function remains challenging because current non-invasive ultrasound techniques have limitations and do not truly represent intrinsic cardiac muscle properties.
Shear wave elastography represents a promising, non-invasive paradigm shift for assessing myocardial stiffness and diastolic function, though technical standardization is still needed.
Does not support routine clinical use; leaves open validation of diagnostic utility in prospective studies.
Echocardiography is essential for the diagnosis and treatment of cardiovascular disease.Assessing left ventricle diastolic function is a major challenge, and several wellknown ultrasound techniques, such as pulsed Doppler for mitral flow, tissue Doppler, and myocardial strain, are used to non-invasively estimate left atrial filling pressure.Although widely available, this approach has several limitations and does not truly represent the intrinsic properties of the cardiac muscle.However, cardiac elastography can be studied noninvasively by estimating myocardial stiffness through shear wave propagation speed in cardiac tissue.Elastography is already widely used to assess stiffness in other tissue types, such as thyroid, liver, and breast.In the context of cardiological assessment, this technique has already been successfully used in diseases such as cardiac amyloidosis and hypertrophic cardiomyopathy.This article aims to review the main concepts of this promising technique and present the published experiences of national and international services.

Fernandes et al. (2023) conducted a review in Cardiomyopathies (e.g., cardiac amyloidosis, hypertrophic cardiomyopathy). Shear wave elastography vs. Conventional echocardiography or invasive catheterization was evaluated. Shear wave elastography is a promising non-invasive technique for estimating myocardial stiffness, offering potential diagnostic value for cardiomyopathies like amyloidosis and hypertrophic cardiomyopathy.
