An Unusual Congenital Heart Disease: Giant Left Atrial Appendage

Methodist DeBakey Cardiovascular Journal, 2022
A 52-year-old female was admitted to our hospital in April 2021 with dyspnea. She was discharged from the hospital 3 weeks ago due to the diagnosis of pneumonia caused by coronavirus disease 2019 (COVID-19).

La orejuela izquierda como fuente de accidentes cerebrovasculares: cerrar (y cómo), o no cerrar (y por qué) [PDF]

, 2012
The left atrial appendage is considered the main source of emboli in strokes in patients with atrial fibrillation. Oral anticoagulant therapy significantly reduces the risk of cerebral embolic events compared to aspirin, but it is ...

Fetal heterotaxy with tricuspid atresia, pulmonary atresia, and isomerism of the right atrial appendages at 22 weeks. [PDF]

, 2013
We report the accurate prenatal diagnosis at 22 weeks gestation of right atrial isomerism in association with tricuspid atresia. Several distinctive sonographic features of isomerism of the right atrial appendages were present in this fetus: complex ...

Left atrial appendage occlusion.

International journal of preventive medicine, 2013
Left atrial appendage (LAA) occlusion is a treatment strategy to prevent blood clot formation in atrial appendage. Although, LAA occlusion usually was done by catheter-based techniques, especially percutaneous trans-luminal mitral commissurotomy (PTMC), it can be done during closed and open mitral valve commissurotomy (CMVC, OMVC) and mitral valve ...

Left Atrial Appendage Exclusion for Atrial Fibrillation [PDF]

Heart Failure Clinics, 2014
Percutaneous left atrial appendage (LAA) closure is being increasingly used as a treatment strategy to prevent stroke in patients with atrial fibrillation (AF) who have contraindications to anticoagulants. Several approaches and devices have been developed in the last few years, each with their own unique set of advantages and disadvantages.

Chemically Doped Conductive Polymers for Wearable Health Monitoring

Advanced Materials Technologies, EarlyView.
Among conductive polymers, poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), polyaniline (PANI), and polypyrrole (PPy) are the most studied and applied. Chemical doping significantly boosts intrinsic conductivity and mechanical robustness.

Factors associated with left atrial appendage thrombus (results of a retrospective analysis)

Journal of V. N. Karazin Kharkiv National University: Series Medicine
Background. Atrial fibrillation is the most common type of arrhythmia and, due to thrombus formation in the left atrial appendage, is associated with a significant increase in the risk of thromboembolic complications, primarily ischemic stroke, transient

Can the vicious cycle of obscure or intractable gastrointestinal bleeding be broken in patients with atrial fibrillation subject to anticoagulant therapy? The role of percutaneous left atrial appendage closure [PDF]

, 2018
Gastrointestinal bleeding of obscure origin or with an intractable cause is particularly common in patients with atrial fibrillation subject to oral anticoagulant therapy.

Direct Gravity‐Induced Modulation of Cardiac Conduction Pathways Evidenced Through Propagation Features in Electrophysiological Mapping

Advanced Materials Technologies, EarlyView.
A high‐density wearable body‐surface potential mapping array reveals how gravity reshapes cardiac conduction in real time. By resolving spatiotemporal delay patterns invisible to conventional ECG, the platform uncovers posture‐dependent electrophysiological adaptations across the thorax.
