Nuñez-Garcia, Marta; Bernardino Perez, Gabriel; Alarcón, Francisco; Caixal, Gala; Mont, Lluís; Camara, Oscar; Butakoff, Constantine (Institute of Electrical and Electronics Engineers (IEEE), 2020)Two-dimensional representation of 3D anatomical structures is a simple and intuitive way for analysing patient information across populations and image modalities. While cardiac ventricles, especially the left ventricle, ...
-
Lluc Álvarez, Èric (Universitat Pompeu Fabra, 2019-10-21)The functioning of the heart, which main role is pumping blood to the rest of the body, is the result of a complex combination of multi-scale physical processes from the molecular to the tissue level. The predominance of ...
-
Morales, Xabier; Mill, Jordi; Simeon, Guillem; Juhl, Kristine A.; De Backer, Ole; Paulsen, Rasmus R.; Camara, Oscar (Springer, 2021)The assessment of left atrial appendage (LAA) thrombogenesis has experienced major advances with the adoption of patient-specific computational fluid dynamics (CFD) simulations. Nonetheless, due to the vast computational ...
-
Coderch-Navarro, Sergi; Berjano, Enrique J.; Camara, Oscar; González-Suárez, Ana (Taylor & Francis, 2021)Purpose: While the standard setting during radiofrequency catheter ablation (RFCA) consists of applying low power for long times, a new setting based on high power and short duration (HPSD) has recently been suggested as ...

Doste Beltrán, Rubén; Sebastián Aguilar, Rafael, 1978-; Gomez, Juan Francisco; Soto-Iglesias, David; Alcaine, Alejandro; Mont, Lluís; Berruezo Sánchez, Antonio; Penela, Diego; Camara, Oscar (Oxford University Press, 2020)Aims A pre-operative non-invasive identification of the site of origin (SOO) of outflow tract ventricular arrhythmias (OTVAs) is important to properly plan radiofrequency ablation procedures. Although some algorithms based ...
-
Planas, Eric; Mill, Jordi; Olivares, Andy L.; Morales, Xabier; Pons Vidal, Maria Isabel; Iriart, Xavier; Cochet, Hubert; Camara, Oscar (Springer, 2021)Atrial fibrillation (AF) is one of the most common cardiac arrhythmias and is associated to an increasing risk of stroke. Most AF- related strokes are formed in the left atrial appendage (LAA). To prevent thrombus ...

Loncaric, Filip; Camara, Oscar; Piella Fenoy, Gemma; Bijnens, Bart (Elsevier, 2020)Cardiac imaging is a crucial component in the management of patients with heart disease, and as such it influences multiple, inter-related parts of the clinical workflow: physician-patient contact, image acquisition, image ...
-
Cetin, Irem (Universitat Pompeu Fabra, 2022-05-26)El diagnóstico asistido por ordenador de enfermedades cardiovasculares (CVD) con resonancia magnética cardíaca (CMR) es un campo importante de investigación para el fenotipado avanzado de imágenes cardíacas. Las mediciones ...
