AF and in-hospital mortality in COVID-19 patients.
Kotadia, ID; Dias, M; Roney, C; Parker, RA; O'Dowling, R; Bodagh, N; Lemus-Solis, J-A; O'Hare, D; Sim, I; Newby, D (Elsevier, 2023-11)BACKGROUND: There are conflicting data on whether new-onset atrial fibrillation (AF) is independently associated with poor outcomes in COVID-19 patients. This study represents the largest dataset curated by manual chart ... -

Roney, CH; Sillett, C; Whitaker, J; Lemus, JAS; Sim, I; Kotadia, I; O'Neill, M; Williams, SE; Niederer, SA (2021) -
Atrial CARdiac Magnetic resonance imaging in patients with embolic stroke of unknown source without documented Atrial Fibrillation (CARM-AF): Study design and clinical protocol.
Kotadia, ID; O'Dowling, R; Aboagye, A; Sim, I; O'Hare, D; Lemus-Solis, J-A; Roney, CH; Dweck, M; Chiribiri, A; Plein, S (2022-04)BACKGROUND: Initiation of anticoagulation therapy in ischemic stroke patients is contingent on a clinical diagnosis of atrial fibrillation (AF). Results from previous studies suggest thromboembolic risk may predate clinical ... -

Evaluation of an open-source pipeline to create patient-specific left atrial models: A reproducibility study.
Solís-Lemus, JA; Baptiste, T; Barrows, R; Sillett, C; Gharaviri, A; Raffaele, G; Razeghi, O; Strocchi, M; Sim, I; Kotadia, I (Elsevier, 2023-08)This work presents an open-source software pipeline to create patient-specific left atrial models with fibre orientations and a fibrDEFAULTosis map, suitable for electrophysiology simulations, and quantifies the intra and ... -
Fully Automatic Atrial Fibrosis Assessment Using a Multilabel Convolutional Neural Network
Razeghi, O; Sim, I; Roney, CH; Karim, R; Chubb, H; Whitaker, J; O'Neill, L; Mukherjee, R; Wright, M; O'Neill, M (American Heart Association, Inc, 2020)Background: Pathological atrial fibrosis is a major contributor to sustained atrial fibrillation. Currently, late gadolinium enhancement (LGE) scans provide the only noninvasive estimate of atrial fibrosis. However, ... -
