Systolic left ventricular long axis function during dobutamine stress echocardiography.
AIMS To compare long-axis function and wall motion analysis for the detection of significant coronary artery stenoses in patients with single and multivessel disease. METHODS AND RESULTS We performed dobutamine stress echocardiography in 67 subjects, 14 with normal coronary anatomy, and 53 with significant coronary disease. A blunted increase in mean long-axis shortening of <0.25 cm was the b...
متن کاملLow dose dobutamine stress echocardiography predicts the improvement of left ventricular systolic function in dilated cardiomyopathy.
OBJECTIVE To determine whether dobutamine stress echocardiography can predict the improvement of left ventricular systolic function in patients with dilated cardiomyopathy (DCM). METHODS Myocardial contractile reserve, as assessed by dobutamine stress echocardiography, was determined in 18 patients with DCM (mean (SD) age 53 (13) years, left ventricular ejection fraction (LVEF) 28 (10)%) and ...
متن کاملMitral Annular Systolic Velocities Predict Left Ventricular Wall Motion Abnormality During Dobutamine Stress Echocardiography
BACKGROUND Longitudinal systolic left ventricular contraction is complementary to the radial performance and can be assessed using tissue Doppler imaging (TDI). This study was performed to evaluate the contribution of mitral annular systolic velocities using TDI after dobutamine stress echocardiography (DSE). METHODS AND RESULTS Fifty subjects with suspected coronary artery disease and chest ...
متن کاملAssessment of regional long-axis function during dobutamine echocardiography.
Echocardiographic analysis of regional left ventricular function is based upon the assessment of radial motion. Long-axis motion is an important contributor to overall function, but has been difficult to evaluate clinically until the recent development of tissue Doppler techniques. We sought to compare the standard visual assessment of radial motion with quantitative tissue Doppler measurement ...
متن کامل[Left ventricular free wall rupture during dobutamine stress echocardiography].
Dobutamine stress echocardiography is associated with a very low rate of serious complications, lower than 0.5% (death, infarction or sustained ventricular tachycardia). We report the case of a 75 year-old female patient that suffered a fatal left ventricular free wall rupture during a dobutamine stress echocardiography after acute myocardial infarction.
