Diastolic function in Chagas' disease: An echo and tissue Doppler imaging study

Diastolic function in Chagas' disease: an echo and tissue Doppler imaging study.

AIMS With the purpose of studying left ventricular filling in Chagas' disease (Chd), we evaluated 169 patients with Chd using echocardiography and Doppler and tissue Doppler imaging (TDI). METHODS AND RESULTS The patients were divided into four groups according to the pattern of left ventricular filling: Group 0--normal filling pattern, Group 1--abnormal relaxation, Group 2--pseudonormal flow...

Diastolic Function (Doppler Tissue Imaging) in the Indeterminate Form of Chagas' Disease

Doppler tissue imaging to assess systolic function in Chagas' disease.

OBJECTIVE To assess the usefulness of Doppler tissue imaging (DTI) for evaluating the systolic function of chagasic patients with and without electrocardiographic abnormalities, in comparision with echocardiographic study. METHODS We studied 77 patients divided into 3 groups as follows: group 1 - control; group 2 - chagasic patients with normal electrocardiographic findings; and group 3 - cha...

Total average diastolic longitudinal displacement by colour tissue doppler imaging as an assessment of diastolic function

BACKGROUND The current method for a non-invasive assessment of diastolic dysfunction is complex with the use of algorithms of many different echocardiographic parameters. Total average diastolic longitudinal displacement (LD), determined by colour tissue Doppler imaging (TDI) via the measurement of LD during early diastole and atrial contraction, can potentially be used as a simple and reliable...

Regional diastolic function in ischaemic heart disease using pulsed wave Doppler tissue imaging.

AIMS The aim of this study was to determine the utility of pulsed wave Doppler tissue imaging in the evaluation of regional left ventricular diastolic function in patients with ischaemic heart disease. METHODS AND RESULTS In 30 normal subjects and 43 patients with ischaemic heart disease, Doppler tissue imaging was performed in each of the 16 segments of the myocardium. The following diastoli...
