State of the art simulations of aortic haemodynamics feature full fluid-structure interaction (FSI) and coupled 0D boundary conditions. Such analyses require not only significant computational resource but also weeks to months of run time, which compromises the effectiveness of their translation to a clinical workflow. This article employs three(More)
Analysis of the cardiovascular system represents a classical problem in which the solid and fluid phases interact intimately, and so is a rich field of application for state-of-the-art fluid-solid interaction (FSI) analyses. In this paper, we focus on the human aorta. Solution of the full FSI problem requires knowledge of the material properties of the wall(More)
Introduction A single-phase 3d steady-state-free precession whole heart approach with respiratory navigator gating and ECG triggering (3d SSFP) is now frequently used for diagnostic imaging in children with congenital heart disease (CHD). However, certain cardiac structures may be better assessed during the systolic and others in the diastolic rest period.(More)
Results Four patients were studied (indication was decreased exercise tolerance). Median (range) age was 9.2 years (5.9-11.6). Heart rate (HR) increased at both levels of stress: mean (standard deviation) at rest 60(±7.0), 10mcg/kg/min 110.8(±13.7), 20mcg/kg/min 137.5(±7.0). The rate of increase between rest and 10mcg/kg/min appeared higher than in the(More)
