Purpose .– Myocardial involvement in Friedreich’s ataxia (FA) is characterized by iron deposits, diffuse fibrosis and focal necrosis. We hypothesized that subclinical left ventricular (LV) dysfunction might occur in patients…
Objectives .– In a series of patients with severe symptomatic aortic stenosis (AS), we sought to assess the value of left ventricular global longitudinal strain (GLS) using 2D speckle tracking…
Background and objectives .– Proportion of non-responders to cardiac resynchronization therapy (CRT) is high (≥ 30%). Echocardiography has been recently shown to predict a CRT-induced improvement in heart failure with…
Introduction .– Echocardiography is a key consideration in the management of diastolic heart failure, the measurement of ejection fraction of left ventricle is therefore fundamental. Objective .– In this work…
Purpose .– Although heart failure with normal ejection fraction (HFNEF) is a frequent disease, physiopathologic mechanisms are still controversial. We hypothesized that elevated arterial stiffness and impaired diastolic reserve could…
Introduction .– A heart failure with preserved ejection fraction (HFPEF) is present in half the patients with heart failure (HF); the prognosis in more recent studies has been shown to…
Introduction .– In patients with chronic heart failure, echocardiography provides important information on the mechanism of heart failure (HF) and defining the severity of the disease. The aim of our…
Introduction .– Little study analyzed the effect of betablocker on echocardiographic, functional parameters and the capacity of exercise in case of heart failure. Aim .– To analyze the impact of…
Objectives .– We studied the effects of cardiac resynchronization therapy (CRT) on functional mitral regurgitation in heart failure (HF) patients. Background .– Functional mitral regurgitation (FMR) is a common finding…
Background .– Left ventricular (LV) diastolic dysfunction is prevalent in the community. Previous studies have reported an association between diastolic function and atrial dimension. Objective .– The aim of this…
