Echocardiography strain: why is it used more and more?
Full text linkIn the last decade, speckle tracking echocardiography (STE) has acquired a fundamental role in the evaluation of the systolic function of the left ventricle, with several advantages over the Doppler method, including angle independence, greater reproducibility, and rapidity of image acquisition. Speckle tracking finds application in various pathologies, ranging from ischaemic heart disease, to cardiomyopathies, to heart failure, both with reduced and preserved ejection fraction (EF), in which the EF is not a reliable prognostic marker and the estimate of left ventricular function by means of ‘strain’ is of crucial utility. In addition, the strain of the left atrium finds application in many clinical contexts as an early index of diastolic dysfunction and left ventricular filling pressures. Finally, the strain of the right ventricle is of particular prognostic importance in the evaluation of heart failure, particularly in its advanced form, becoming an indispensable index in the evaluation of patients who are candidates for advanced therapeutic strategies. This document aims to describe the various fields of clinical application of STE, with particular emphasis on its diagnostic and prognostic role, so much that it is now integrated into the algorithms for managing multiple pathologies in daily clinical practice

The left atrium and the right ventricle: two supporting chambers to the failing left ventricle
No full textHeart failure (HF) is mainly caused by left ventricular (LV) impairment of function, hence detailed assessment of its structure and function is a clinical priority. The frequent involvement of the left atrium (LA) and the right ventricle (RV) in the overall cardiac performance has recently gained significant interest with specific markers predicting exercise intolerance and prognosis being proposed. The LA and RV are not anatomically separated from the LV, while the LA controls the inlet the RV shares the interventricular septum with the LV. Likewise, the function of the two chambers is not entirely independent from that of the LV, with the LA enlarging to accommodate any rise in filling pressures, which could get transferred to the RV via the pulmonary circulation. In the absence of pulmonary disease, LA and RV function may become impaired in patients with moderate-severe LV disease and raised filling pressures. These changes can often occur irrespective of the severity of systolic dysfunction, thus highlighting the important need for critical assessment of the function of the two chambers. This review evaluates the pivotal role of the left atrium and right ventricle in the management of HF patients based on the available evidence
Speckle tracking echocardiography in cardiac amyloidosis
No full textSpeckle tracking echocardiography is an imaging method, based on analysis of 2D echocardiographic images, that is useful in providing information on tissue deformation in different cardiac diseases. Cardiac amyloidosis is a complex pathological entity that can be confused with other causes responsible for cardiac hypertrophy, and for this reason, it can be misdiagnosed, especially in the early stages. Cardiac magnetic resonance and endomyocardial biopsy are reference methods for specific diagnosis, but their use is limited by a number of factors, both of a logistical and technical nature. Considering the limits of standard 2D echocardiography, speckle tracking echocardiography can be a useful method to enhance the clinical suspicion, to provide prognostic information, and to address patients more appropriately towards reference methods for definitive diagnosis
