Autor: Wing Keung Cheung, Robert Bell, Arjun Nair, Leon J. Menezes, Riyaz Patel, Simon Wan, Kacy Chou, Jiahang Chen, Ryo Torii, Rhodri H. Davies, James C. Moon, Daniel C. Alexander, Joseph Jacob

Publikováno v: IEEE Access, Vol 9, Pp 108873-108888 (2021)

Early detection and diagnosis of coronary artery disease could reduce the risk of developing a heart attack. The coronary arteries are optimally visualised using computed tomography coronary angiography (CTCA) imaging. These images are reviewed by sp

Computational Fluid Dynamic Analysis of the Left Atrial Appendage to Predict Thrombosis Risk

Autor: Giorgia Maria Bosi, Andrew Cook, Rajan Rai, Leon J. Menezes, Silvia Schievano, Ryo Torii, Gaetano Burriesci

Publikováno v: Frontiers in Cardiovascular Medicine, Vol 5 (2018)

During Atrial Fibrillation (AF) more than 90% of the left atrial thrombi responsible for thromboembolic events originate in the left atrial appendage (LAA), a complex small sac protruding from the left atrium (LA). Current available treatments to pre

Impact of Inflow Boundary Conditions on the Calculation of CT-Based FFR

Autor: Ernest W. C. Lo, Leon J. Menezes, Ryo Torii

Publikováno v: Fluids, Vol 4, Iss 2, p 60 (2019)

Background: Calculation of fractional flow reserve (FFR) using computed tomography (CT)-based 3D anatomical models and computational fluid dynamics (CFD) has become a common method to non-invasively assess the functional severity of atherosclerotic n
