    Segmentation of medical images, particularly late gadolinium-enhanced magnetic resonance imaging (LGE-MRI) used for visualizing diseased atrial structures, is a crucial first step for ablation treatment of atrial fibrillation. ...
  • Estimating 3D ventricular shape from 2D echocardiography: feasibility and effect of noise
    Bernardino Perez, Gabriel; Butakoff, Constantine; Nuñez-Garcia, Marta; Sarvari, Sebastian Imre; Rodriguez López, Mérida; Crispi Brillas, Fàtima; González Ballester, Miguel Ángel, 1973-; Craene, Mathieu de; Bijnens, Bart (Springer, 2017)
    Many cardiac diseases are associated with changes in ventricular shape. However, in daily practice, the heart is mostly assessed by 2D echocardiography only. While 3D techniques are available, they are rarely used. In this ...
  • Fast quasi-conformal regional flattening of the left atrium
    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, ...
  • In silico optimization of left a trial appendage occluder implantation using interactive and modeling tools
    Aguado, Ainhoa M.; Olivares Miyares, Andy Luis; Yagüe, Carlos; Silva, Etelvino; Nuñez-Garcia, Marta; Fernandez-Quilez, Álvaro; Mill, Jordi; Genua, Ibai; Arzamendi, Dabit; De Potter, Tom; Freixa, Xavier; Camara, Oscar (Frontiers, 2019)
    According to clinical studies, around one third of patients with atrial fibrillation (AF) will suffer a stroke during their lifetime. Between 70 and 90% of these strokes are caused by thrombus formed in the left atrial ...
  • Persistence of cardiac remodeling in preadolescents with fetal growth restriction
    Imre Sarvari, Sebastian; Rodriguez López, Mérida; Nuñez-Garcia, Marta; Sitges, Marta; Sepúlveda-Martínez, Álvaro; Camara, Oscar; Butakoff, Constantine; Gratacós Solsona, Eduard; Bijnens, Bart; Crispi Brillas, Fàtima (American Hearth Association, 2017)
    Fetal growth restriction (FGR) affects 5% to 10% of newborns and is associated with increased cardiovascular mortality in adulthood. We evaluated whether prenatal cardiovascular changes previously demonstrated in FGR persist ...
  • Preferential regional distribution of atrial fibrosis in posterior wall around left inferior pulmonary vein as identified by late gadolinium enhancement cardiac magnetic resonance in patients with atrial fibrillation
    Benito, Eva M.; Cabanelas, Nuno; Nuñez-Garcia, Marta; Alarcón, Francisco; Figueras i Ventura, Rosa M.; Soto-Iglesias, David; Guasch, Eduard; Prat Gonzàlez, Susanna; Perea, Rosario J.; Borràs, Roger; Butakoff, Constantine; Camara, Oscar; Bisbal, Felipe; Arbelo, Elena; Tolosana, José Maria; Brugada, Josep; Berruezo Sánchez, Antonio; Mont, Lluís (Oxford University Press, 2018)
    Aims: Left atrial (LA) fibrosis can be identified by late gadolinium enhancement cardiac magnetic resonance (LGE-CMR) in patients with atrial fibrillation (AF). However, there is limited information about anatomical fibrosis ...
  • Sensitivity analysis of geometrical parameters to study haemodynamics and thrombus formation in the left atrial appendage
    García-Isla, Guadalupe; Olivares Miyares, Andy Luis; Silva, Etelvino; Nuñez-Garcia, Marta; Butakoff, Constantine; Sanchez-Quintana, Damian; Morales, Hernán G.; Freixa, Xavier; Noailly, Jérôme; De Potter, Tom; Camara, Oscar (Wiley, 2018)
    The left atrial appendage (LAA) is a complex and heterogeneous protruding structure of the left atrium (LA). In atrial fibrillation patients, it is the location where 90% of the thrombi are formed. However, the role of the ...
  • Sensitivity analysis of in silico fluid simulations to predict thrombus formation after left atrial appendage occlusion
    Mill, Jordi; Agudelo, Victor; Olivares Miyares, Andy Luis; Pons Vidal, Maria Isabel; Silva, Etelvino; Nuñez-Garcia, Marta; Morales Ferez, Xabier; Arzamendi, Dabit; Freixa, Xavier; Noailly, Jérôme; Camara, Oscar (MDPI, 2021)
    Atrial fibrillation (AF) is nowadays the most common human arrhythmia and it is considered a marker of an increased risk of embolic stroke. It is known that 99% of AF-related thrombi are generated in the left atrial ...
  • Standard quasi-conformal flattening of the right and left atria
    Nuñez-Garcia, Marta; Bernardino Perez, Gabriel; Doste Beltrán, Rubén; Zhao, Jichao; Camara, Oscar; Butakoff, Constantine (Springer, 2019)
    Two-dimensional standard representations of 3D anatomical structures are a simple and intuitive way for analysing patient information across populations and image modalities. They also allow convenient visualizations that ...
  • The reproducibility of late gadolinium enhancement cardiovascular magnetic resonance imaging of post-ablation atrial scar: a cross-over study
    Chubb, Henry; Karim, Rashed; Roujol, Sébastien; Nuñez-Garcia, Marta; Williams, Steven E.; Whitaker, John; Harrison, James; Butakoff, Constantine; Camara, Oscar; Chiribiri, Amedeo; Schaeffter, Tobias; Wright, Matthew; O'Neill, Mark; Razavi, Reza (BioMed Central, 2018)
    Background: Cardiovascular magnetic resonance (CMR) imaging has been used to visualise post-ablation atrial scar (PAAS), generally employing a three-dimensional (3D) late gadolinium enhancement (LGE) technique. However the ...
