Coronary 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 کاملCORONARY BLOOD FLOW Noninvasive Assessment of Coronary Flow Velocity and Coronary Flow Velocity Reserve in the Left Anterior Descending Coronary Artery by Doppler Echocardiography Comparison With Invasive Technique
Objectives. The purpose of this study was to evaluate whether transthoracic Doppler echocardiography (TTDE) can reliably measure coronary flow velocity (CFV) and coronary flow velocity reserve (CFVR) in the left anterior descending coronary artery (LAD) in the clinical setting. Background. Coronary flow velocity measurement has provided useful clinical and physiologic information. Advancement i...
متن کاملCoronary flow velocity pattern and coronary flow reserve by contrast-enhanced transthoracic echocardiography predict long-term outcome in heart transplantation.
BACKGROUND We assessed coronary flow velocity pattern and coronary flow reserve (CFR) by contrast-enhanced transthoracic echocardiography (CE-TTE) as markers of major adverse cardiac events (MACE) related to cardiac allograft vasculopathy (CAV) after heart transplantation (HT). METHODS AND RESULTS Deceleration time of diastolic flow velocity (DDT) and CFR were measured in the left anterior de...
متن کاملCoronary flow velocity and coronary flow velocity reserve in children with ventricular septal defect.
To assess coronary flow characteristics in congenital heart defect with left ventricular (LV) volume overload, we examined 24 children (mean 12.1 +/- 7.1 months) with ventricular septal defect. The pulmonary to systemic flow ratio ranged from 1.1 to 3.0. Control group consisted of 10 age-matched children who had a history of Kawasaki disease with angiographically normal coronary artery in the a...
متن کاملCoronary flow velocity reserve in three major coronary arteries by transthoracic echocardiography for the functional assessment of coronary artery disease: a comparison with fractional flow reserve.
AIMS Coronary flow velocity reserve (CFVR) measurement in three major coronary arteries by transthoracic echocardiography is a promising and non-invasive method for detecting myocardial ischaemia. Its value when compared with fractional flow reserve (FFR) is unknown. Our aim was to determine the diagnostic accuracy of CFVR in three major coronary arteries for detecting ischaemia compared with F...
