The Impact of Left Atrium Appendage Morphology on Stroke Risk Assessment in Atrial Fibrillation: A Computational Fluid Dynamics Study

open access: yesFrontiers in Physiology, 2019
Atrial fibrillation (AF) carries out a 5-fold increase in stroke risk, related to embolization of thrombi clotting in left atrium (LA). Left atrial appendage (LAA) is the site with the highest blood stasis which causes thrombus formation.

Analysis of a coupled fluid‐structure interaction model of the left atrium and mitral valve

open access: yesInternational Journal for Numerical Methods in Biomedical Engineering, 2019
We present a coupled left atrium‐mitral valve model based on computed tomography scans with fibre‐reinforced hyperelastic materials. Fluid‐structure interaction is realised by using an immersed boundary‐finite element framework.

Giant left atrium [PDF]

open access: yesThorax, 1970
Radiographic evidence of asymmetrical enlargement of the left atrium without atrial infarction is presented. Giant atrial enlargement is rarely symmetrical, the atrial appendage can contribute to the enlargement, and the giant atrium can be effectively trimmed.

Transcriptomic profile analysis of the left atrium in spontaneously hypertensive rats in the early stage

open access: yesFrontiers in Pharmacology, 2022
Left atrial remodeling, characterized by enlargement and hypertrophy of the left atrium and increased fibrosis, was accompanied by an increased incidence of atrial fibrillation.

Region specific parasympathetic nerve remodeling in the left atrium contributes to creation of a vulnerable substrate for atrial fibrillation.

open access: yesJCI Insight, 2019
Atrial fibrillation (AF) is the most common heart rhythm disorder and a major cause of stroke. Unfortunately, current therapies for AF are suboptimal, largely because the molecular mechanisms underlying AF are poorly understood.

Case Report: Double-Decker Repair of Partial Pulmonary Venous Return Into the Coronary Sinus

open access: yesFrontiers in Cardiovascular Medicine, 2022
We present a case of persistent left superior vena cava (LSVC) draining into the right atrium (RA) via the coronary sinus (CS), while the left superior pulmonary vein returns abnormally to the CS.

Morphology and morphometry of pulmonary veins and the left atrium in multi-slice computed tomography

open access: yesSurgical and Radiologic Anatomy, 2019
PurposePulmonary veins are involved in pathogenesis and treatment of atrial fibrillation and structures at risk during thoracic surgeries. There is lack of data regarding pulmonary vein morphology and morphometry in normal population.MethodsThe study was

Anatomic Study of Number of Pulmonary Veins Draining into the Left Atrium and Their Variations

open access: yesJournal of Medical Sciences and Health, 2020
Introduction: Pulmonary veins originate from the alveolar capillary plexus and carry oxygenated blood to the left atrium. The fibrous pericardium is perforated by the pulmonary veins and they drain separately in the posterosuperior aspect of the left ...
