Longitudinal strain by speckle tracking echocardiography in constrictive pericarditis

Posterior longitudinal strain by speckle tracking echocardiography, marker of cardiac amyloidosis?

Background Cardiac amyloidosis (CA) is a condition of poor prognosis. The three major forms of amyloidosis are light chain (AL), hereditary transthyretin (M-TTR), and wildtype transthyretin (WT-TTR). Two-dimensional (2D) echocardiography measurement of longitudinal strain (LS) has been reported to be useful in the diagnosis of CA. Regional distribution of LS in CA and its diagnostic value in de...

Left Atrial Systolic and Diastolic Dysfunction in Patients with Chronic Constrictive Pericarditis: A Study Using Speckle Tracking and Conventional Echocardiography

BACKGROUND Left atrial (LA) function plays an important role in the maintenance of cardiac output, however, in patients with constrictive pericarditis (CP), whether pericardial restriction and adhesion can lead to LA dysfunction, and the characteristics of LA function remain unclear. The aim of the study is to compare the left atrial (LA) function of patients with CP to that of healthy study pa...

Redefining Effusive-Constrictive Pericarditis with Echocardiography

BACKGROUND Effusive-constrictive pericarditis (ECP) is traditionally diagnosed by using the expensive and invasive technique of direct pressure measurements in the pericardial space and the right atrium. The aim of this study was to assess the diagnostic role of echocardiography in tuberculous ECP. METHODS Intrapericardial and right atrial pressures were measured pre- and post-pericardiocente...

Radial and longitudinal strain and strain rate assessed by speckle-tracking echocardiography in dogs with myxomatous mitral valve disease.

BACKGROUND Assessment of left ventricular (LV) function using conventional echocardiographic methods is difficult in mitral regurgitation (MR) owing to altered hemodynamic loading conditions. Newer methods such as speckle-tracking echocardiography (STE) provide assessment of LV strain (St) and strain rates (SR). HYPOTHESES Global St and SR are 1) decreased in dogs with clinical signs of conge...
