Assessment of coronary flow velocity with transthoracic Doppler echocardiography during dobutamine stress echocardiography.
OBJECTIVES The purpose of this study was to evaluate the feasibility of measuring coronary flow velocity (CFV) by transthoracic Doppler echocardiography (TTDE) in the left anterior descending coronary artery (LAD) during contrast-enhanced dobutamine stress echocardiography (DSE). We also assessed the value of TTDE for detecting stress-induced myocardial ischemia in the LAD territory. BACKGROU...
متن کاملCoronary Flow Velocity Reserve during Dobutamine Stress Echocardiography
BACKGROUND A coronary flow velocity reserve (CFVR)≥2 is adequate to infer a favorable prognosis or the absence of significant coronary artery disease. OBJECTIVE To identify parameters which are relevant to obtain CFVR (adequate or inadequate) in the left anterior descending coronary artery (LAD) during dobutamine stress echocardiography (DSE). METHODS 100 patients referred for detection of ...
متن کاملPre-ejection tissue-Doppler velocity changes during low dose dobutamine stress predict segmental myocardial viability.
INTRODUCTION We tested the hypothesis that low dose dobutamine stress echocardiography (LDDSE) combined with tissue Doppler imaging (TDI) can be used for the quantitative assessment of the content of viable myocardium. METHODS Forty-one patients with coronary artery disease and left ventricular dysfunction (ejection fraction < or =40%), already scheduled for revascularisation, underwent echoc...
متن کاملEvaluation of transmural distribution of viable muscle by myocardial strain profile and dobutamine stress echocardiography.
Transmural distribution of viable myocardium in the ischemic myocardium has not been quantified and fully elucidated. To address this issue, we evaluated transmural myocardial strain profile (TMSP) in dogs with myocardial infarction using a newly developed tissue strain imaging. TMSP was obtained from the posterior wall at the epicardial left ventricular short-axis view in 13 anesthetized open-...
متن کاملThe Value of Using Pulsed Tissue Doppler Mitral Annulus Velocity during Dobutamine Stress Echocardiography for Assessment of Myocardial Viability in Patients with Coronary Artery Disease before Revasularization
Patients and methods: The study group included 40 patients, selected consecutively from patients presented to Ain Shams university Hospitals with coronary artery disease as proved by diagnostic coronary angiography and recommended for potential coronary revascularization. Each patient underwent baseline transthoracic echocardiography, in addition to low dose dobutamine echocardiography using TD...
