New concepts for interpretation of intracoronary velocity and pressure tracings.
The development of quantitative angiography and the introduction of new imaging techniques cannot replace functional methods of assessing the severity of stenosis. Measurement of transstenotic pressure gradient and poststenotic flow velocity using miniaturised sensors with guidewire technology offers an alternative to the conventional non-invasive methods that is immediately applicable in the c...
متن کاملPressure Tracings in Hypertrophic Cardiomyopathy With Dynamic Midventricular Obstruction
A 50-year-old man was admitted for evaluation of syncope. Clinically, he had an irregular pulse and an ejection systolic murmur loudest at the left sternal border. Transthoracic echocardiography revealed hypertrophic cardiomyopathy (HCM) with midventricular obstruction and apical aneurysm with maximum pressure gradient greater than 74 mm Hg. Coronary angiogram showed normal coronary arteries. L...
متن کاملCoronary collateral quantitation in patients with coronary artery disease using intravascular flow velocity or pressure measurements.
OBJECTIVES This study evaluated two methods for the quantitative measurement of collaterals using intracoronary (IC) blood flow velocity or pressure measurements. BACKGROUND The extent of myocardial necrosis after coronary artery occlusion is substantially influenced by the collateral circulation. So far, qualitative methods have been available to assess the human coronary collateral circulat...
متن کاملSubclavian Pulse Tracings
Background Evaluation of regional aortic elastic properties in humans has been hampered by the need for invasive techniques to access instantaneous aortic pressure, wall thickness, and cross-sectional area or diameter. In this study, a new noninvasive method is presented for quantification of regional aortic elastic properties. Methods and Results Twenty-five patients were studied during transe...
متن کاملVelocity-Pressure Coupling on GPU
We explore the possibilities to accelerate simulations in computational fluid dynamics (CFD) by additional graphics processing units (GPUs). By examining some examples of stationary incompressible flows from the industrial practice we demonstrate that the potential speedup obtained by deploying GPU accelerated linear solvers alone is limited if standard segregated algorithms are used. However, ...
