Uncertainty-aware Self-ensembling Model for Semi-supervised 3D Left Atrium Segmentation
International Conference on Medical Image Computing and Computer-Assisted Intervention, 2019Training deep convolutional neural networks usually requires a large amount of labeled data. However, it is expensive and time-consuming to annotate data for medical image segmentation tasks.

Mini‐AbstractA 58‐year‐old woman with a history of mitral valve replacement (MVR) 17 years ago and was admitted to our clinic with dyspnea. Transthoracic examination showed a normal functioning MVR with a very large left atrium which was 209 × 96 mm that was not possible to fit the screen in its entirety.

Giant left atrium syndrome can occasionally occur in patients with rheumatic mitral valve regurgitation and can be responsible for oesophagus and/or airways compression. Abnormally enlarged left atriomegaly creates unusual right chest opacification on radiographs.

Domain and Geometry Agnostic CNNs for Left Atrium Segmentation in 3D Ultrasound
International Conference on Medical Image Computing and Computer-Assisted Intervention, 2018Segmentation 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 ...

Combating Uncertainty with Novel Losses for Automatic Left Atrium Segmentation
STACOM@MICCAI, 2018Segmenting left atrium in MR volume holds great potentials in promoting the treatment of atrial fibrillation. However, the varying anatomies, artifacts and low contrasts among tissues hinder the advance of both manual and automated solutions.

Pyramid Network with Online Hard Example Mining for Accurate Left Atrium Segmentation
STACOM@MICCAI, 2018Accurately segmenting left atrium in MR volume can benefit the ablation procedure of atrial fibrillation. Traditional automated solutions often fail in relieving experts from the labor-intensive manual labeling.

Abstract A case of a local aneurysm of the posterior wall of the left atrium, occurring in a 31-year-old Caucasian female with mitral insufficiency, is reported. The lesion was present on plain roentgenograms and identified by angiography. The differential diagnosis included aneurysmal dilatation of the pulmonary veins, giant left atrium, and left ...

Compliance of left atrium with and without left atrium appendage
American Journal of Physiology-Heart and Circulatory Physiology, 1990Compliance of the left atrial chamber was estimated with and without the appendage intact in six isolated canine left atria. Pressure-volume determinations were measured over a range of 5-30 mmHg for the whole left atrium and were repeated with the appendage excluded. The slope of the pressure vs. normalized volume data for the left atrium without the
