952 Doppler tissue imaging unmasks impairment of long-axis left ventricular contraction in HIV infected patients

Doppler tissue imaging unmasks right ventricular function abnormalities in HIV-infected patients.

BACKGROUND We sought to investigate right ventricular (RV) function with Doppler tissue imaging (DTI) in human immunodeficiency virus (HIV)-infected patients receiving highly-active antiretroviral treatment, without any heart-related symptoms. METHODS We studied 38 asymptomatic HIV patients (aged 44.5 ± 9.2 years, 22 of them men) and 25 age-matched and sex-matched controls. All subjects under...

Assessment of left ventricular torsion in long axis view in patients with chronic stenosis of coronary arteries

Background: Left ventricular torsion is one of the most important biomechanical parameters of heart that routinely is measured in short axis view.  A review of the literature has indicated that assessment of left ventricular torsion in short axis view has some limitations. In the present study, we evaluated whether torsion angle assessment in long axis view can be used as a diagnostic biomechan...

assessment of subclinical left ventricular dysfunction in patients with chronic mitral regurgitation using torsional parameters described by tissue doppler imaging

background: left ventricular (lv) twist is due to oppositely directed apical and basal rotation and has been proposed as a sensitive marker of lv function. we sought to assess the impact of chronic pure mitral regurgitation (mr) on the torsional mechanics of the left human ventricle using tissue doppler imaging. methods: nineteen severe mr patients with a normal lv ejection fraction and 16 non-...

Tissue Doppler imaging as a long-term prognostic index in left ventricular systolic dysfunction.

BACKGROUND Tissue Doppler parameters correlate with left ventricular (LV) filling pressure and can be useful as prognostic indexes for patients with heart failure. OBJECTIVE Determine whether tissue Doppler parameters can predict events during long term follow-up of outpatients with LV systolic dysfunction. METHODS Retrospective study with 73 patients (aged 60.9+/-12.1 years) who underwent ...
