Computational fluid dynamics (CFD) is increasingly being developed for the diagnostics of arterial diseases. Imaging methods such as computed tomography (CT) and angiography are commonly used. However, these have limited spatial resolution and are su

Background— Lack of re-endothelialization and neointimal coverage on stent struts has been put forward as the main underlying mechanism leading to late stent thrombosis. Incomplete stent apposition (ISA) has been observed frequently in patients wit

Optical coherence tomography (OCT) presents high fidelity intracoronary imaging, which may improve the spatial resolution offered by current coronary reconstruction methods. In this study, we applied a new approach to generate patient-specific virtua

TCT-614 Patient-specific Coronary Stenoses Can Be Modeled Using a Combination of Optical Coherence Tomography and Flow Velocities to Accurately Predict Hyperaemic Pressure Gradients

Autor: Ricardo Petraco, Sukhjinder Nijjer, Nicolas Foin, Christopher Broyd, Alun D. Hughes, Justin E. Davies, Yun X. Xu, Ryo Torii, Sayan Sen, Chrysa A. Kousera, Darrel P. Francis

Publikováno v: Journal of the American College of Cardiology. (18):B186

Computational fluid dynamics (CFD) modeling of patient-specific coronary arteries remain limited by image resolution and the phasic nature of flow. Patient-specific pressure and flow data may overcome these limitations. We applied a 3D reconstruction
