Liver Elastography for Complementary Assessment of Heart Failure

Diane Xavier de Ávila et al. Humberto Villacorta Evandro Tinoco Mesquita

Abstract

Liver elastography (LE) assesses the systemic consequences of heart failure (HF). This method may help in the prognostic assessment of patients with HF. HF can secondarily affect the function of various organs and systems, especially the liver, through venous congestion. The purpose of this article is to provide a narrative review of the importance of LE in the complementary evaluation of HF. The hepatic consequences of cardiac disease are sometimes silent, without significant changes in physical examination and/or laboratory tests. In this context, LE has emerged as a recommended non-invasive method to measure liver damage caused by HF.

Role of Shear Wave Elastography in the Assessment of Myocardial Stiffness in Various Cardiomyopathies

Fabio Fernandes et al. Nathalia Conci Santorio Natália de Melo Pereira Caio Rebouças Fonseca Cafezeiro … Aristóteles Comte de Alencar Neto Bruno Vaz Kerges Bueno Fernando Linhares Pereira Maria Cristina Chammas

Abstract

Echocardiography is essential for the diagnosis and treatment of cardiovascular disease. Assessing left ventricle diastolic function is a major challenge, and several well-known 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 non-invasively 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.
