Coronary 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 کاملFlow velocity and predictors of a suboptimal coronary flow velocity reserve after coronary balloon angioplasty.
AIMS This study was conducted to analyse flow velocity parameters and predictors of a suboptimal coronary flow reserve (<2.5) following balloon angioplasty. METHODS Two hundred and twenty-five patients underwent sequential intracoronary Doppler as part of the DEBATE I study. Of these, 183, with complete angiography and Doppler at the 6-month follow-up, were included. Univariate and multivaria...
متن کاملNew method to measure coronary velocity and coronary flow reserve.
Coronary flow reserve (CFR) is an important index of coronary microcirculatory function. The objective of this study was to validate the reproducibility and accuracy of intravascular conductance catheter-based method for measurements of baseline and hyperemic coronary flow velocity (and hence CFR). The absolute coronary blood velocity was determined by measuring the time of transit of a saline ...
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 کاملDeterminants of coronary flow velocity reserve in healthy young men.
The objective of this study was to identify risk markers for attenuated coronary flow velocity reserve (CFVR) that exist in healthy young men without evident atherosclerotic risk factors. Coronary blood flow velocity was measured with transthoracic Doppler echocardiography at baseline and during adenosine infusion in 37 healthy nonsmoking men [mean age, 27 yr (SD 4.0)]. Body composition and dis...
