Domain and Geometry Agnostic CNNs for Left Atrium Segmentation in 3D Ultrasound [PDF]
Medical Image Computing and Computer Assisted Intervention (MICCAI
2018), 2018 Segmentation of the left atrium and deriving its size can help to predict and detect various cardiovascular conditions. Automation of this process in 3D Ultrasound image data is desirable, since manual delineations are time-consuming, challenging and observer-dependent.

Assessment of Left Atrium Motion Deformation Through Full Cardiac Cycle [PDF]
arXivUnlike Right Atrium (RA), Left Atrium (LA) presents distinctive challenges, including much thinner myocardial walls, complex and irregular morphology, as well as diversity in individual's structure, making off-the-shelf methods designed for the Left Ventricle (LV) may not work in the context of the left atrium. To overcome aforementioned challenges, we

European Heart Journal, 2007 A 61-year-old woman presented to our department with symptoms of chest distress and shortness of breath that had worsened in the previous 3 months. She had a history of rheumatic heart disease. A chest x-ray revealed a gross enlargement of the cardiac silhouette. An echocardiogram showed a …

Hierarchical Consistency Regularized Mean Teacher for Semi-supervised 3D Left Atrium Segmentation [PDF]
2021 43rd Annual International Conference of the IEEE Engineering
in Medicine & Biology Society (EMBC), 2021 Deep learning has achieved promising segmentation performance on 3D left atrium MR images. However, annotations for segmentation tasks are expensive, costly and difficult to obtain. In this paper, we introduce a novel hierarchical consistency regularized mean teacher framework for 3D left atrium segmentation.

A geometric multiscale model for the numerical simulation of blood flow in the human left heart [PDF]
Discrete and Continuous Dynamical System - S (2022), 15(8),
2391-2427, 2021 We present a new computational model for the numerical simulation of blood flow in the human left heart. To this aim, we use the Navier-Stokes equations in an Arbitrary Lagrangian Eulerian formulation to account for the endocardium motion and we model the cardiac valves by means of the Resistive Immersed Implicit Surface method.

Systematic Analysis of Gene Expression Differences between Left and Right Atria in Different Mouse Strains and in Human Atrial Tissue [PDF]
, 2011 Background: Normal development of the atria requires left-right differentiation during embryonic development. Reduced expression of Pitx2c (paired-like homeodomain transcription factor 2, isoform c), a key regulator of left-right asymmetry, has recently ...

Non-compliant left atrium masquerading as severe mitral regurgitation on cardiac catheterisation haemodynamics [PDF]
, 2020 A prominent v wave on a capillary wedge or left atrial pressure tracings classically signify significant mitral regurgitation. However, infiltrative disease involving the left atrium and left atrial scar from prior catheter ablation or Maze procedures ...

Left atrial anomalous muscular band as incidental finding during video-assisted mitral surgery [PDF]
, 2018 Congenital fibromuscular bands have been described inleft ventricle or right atrium and have been diagnosed by echocardiography and CT scan. The first report of anomalous band in the left atrium was described in 1897 by Rollestone (1).
