    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 ...
  • 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, ...

    Statistical shape analysis is a powerful tool to assess organ morphologies and find shape changes associated to a particular disease. However, imbalance in confounding factors, such as demographics might invalidate the ...
  • Paun, Bruno (Universitat Pompeu Fabra, 2017-07-24)
    The role of trabeculations and their normal morphological expression in the human heart is still unclear. Clinical studies have shown that excessive trabeculation can cause heart failure due to diastolic and systolic ...
  • Núñez García, Marta (Universitat Pompeu Fabra, 2018-11-21)
    Many aspects related to the pathogenesis and progression of atrial fibrillation (AF) are still not fully understood. In this thesis we have contributed with (1) an automatic framework to segment the left atrium (LA) from ...

    We tested the hypothesis that a machine learning (ML) algorithm utilizing both complex echocardiographic data and clinical parameters could be used to phenogroup a heart failure (HF) cohort and identify patients with ...
  • Paun, Bruno; Bijnens, Bart; Iles, Tinen; Iaizzo, Paul A.; Butakoff, Constantine (Elsevier, 2017)
    Reparameterization of surfaces is a widely used tool in computer graphics known mostly from the remeshing algorithms. Recently, the surface reparameterization techniques started to gain popularity in the field of medical ...

    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 ...
