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.

SYNOPSIS A case of idiopathic dilatation of the left atrium in a 7 month old infant is described. The initial diagnosis was a mediastinal mass, and the correct diagnosis was made at thoracotomy. His course was characterised by atrial arrhythmias for 3 months, but subsequent course was benign and the left atrial dilatation regressed to normal size.

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 Congenital left atrial aneurysm is a rare anomaly that has been reported only five times previously. The usual presenting features include an abnormal chest roentgenogram, an apical systolic murmur and supraventricular tachycardia. Even with cineangiocardiography the diagnosis is uncertain, and the lesion is commonly confused with cardiac ...

Shone's anomaly describes a complex involving multiple left sided cardiac obstructions, namely, parachute deformity of the mitral valve, supravalvular ring of the left atrium, subaortic stenosis and aortic coarctation. We are reporting a case of Shone's anomaly characterised by aortic recoarctation, mitral supravalvular membrane, bicuspid aortic valve,

A74-year-old man was admitted for progressive exertional dyspnea. Physical examination was normal. Echocardiography showed a myxoma-like tumor in the left atrium that impinged to the left ventricle during diastole (Fig 1A). Chest computed tomography revealed the tumor (arrow) originated from the left lower lobar bronchus and descended to the left ...

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 ...

The left atrium is of considerable importance in the natural and surgical story of mitral valve stenosis. It is the first chamber to be affected when the ventricle is being filled; inside it, blood stasis and the pro-coagulant effect that stenosis causes can promote the formation of thrombi that are a considerable factor in the patient’s morbidity and ...

The terminology of the atria has been confusing. The words, auricle, atrium, and appendix (or appendage) are often interchanged. Auricle (L. auricula = ear) has long been used—presumably because of the fancied resemblance of the protuberance of the right-sided chamber to the ear of a dog.

The fully developed human left atrium (LA) consists of the true atrial septum, a superior smooth walled portion, and an inferior trabeculated portion. The smooth walled portion is larger and originates embryologically from the pulmonary veins that combine to form a common pulmonary vein before becoming integrated with the inferior portion of the left ...
