Evaluation of left ventricular dyssynchrony using combined pulsed wave and tissue Doppler imaging
INTRODUCTION The combination of pulsed wave (PW) and tissue Doppler imaging (TDI) has been proposed as a new method to assess left ventricular (LV) mechanical dyssynchrony (LVMD), but results have not been validated. We investigated the correlation of a combination of PW and TDI with a positive response to cardiac resynchronization therapy (CRT). MATERIAL AND METHODS We studied 108 consecutiv...
متن کاملSystolic right ventricular function assessment by pulsed wave tissue Doppler imaging of the tricuspid annulus.
BACKGROUND Systolic right ventricular (RV) function is an important predictor in the course of various congenital and acquired heart diseases. So far, tricuspid annular motion velocity in systole as obtained by pulsed wave tissue Doppler imaging (TDI) has rarely been investigated for RV function assessment in a sizeable adult patient population. METHODS 258 individuals were included in the st...
متن کاملCardiac dysfunction in acromegaly: evidence by pulsed wave tissue Doppler imaging.
OBJECTIVE To verify whether the accuracy of data on myocardial function provided by pulsed-wave tissue Doppler imaging (PWTDI), a new echocardiographic application that allows quantitative measurements of myocardial wall velocities, could help towards a better understanding of the natural history of acromegalic cardiomyopathy. DESIGN Eighteen patients with active acromegaly (ten men and eight...
متن کاملIsovolumic contraction time by pulsed-wave Doppler tissue imaging in aortic stenosis.
BACKGROUND Doppler Tissue Imaging (DTI) has been evaluated in ischaemic heart disease and some cardiomyopathies. In patients with aortic stenosis (AS), left ventricular contraction is slowered. This study aimed to evaluate the possible role of the measurement of isovolumic contraction time (ICT) by DTI in the evaluation of AS severity. METHODS The study population constitutes 30 patients: 15 ...
متن کاملRegional 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...
