Different Techniques of Surgical Left Atrial Appendage Closure and Their Efficacy: A Systematic Review

Reviews in Cardiovascular Medicine, 2023
Background: Atrial fibrillation has been identified as an independent risk factor for thromboembolic events. Since 1948 different surgical techniques have described the feasibility and the rationale of left atrial surgical appendage closure.

Electrophysiological Mechanisms of Atrial Flutter [PDF]

, 2006
Atrial flutter (AFL) is a common arrhythmia in clinical practice. Several experimental models such as tricuspid regurgitation model, tricuspid ring model, sterile pericarditis model and atrial crush injury model have provided important information about

Giant left atrial appendage aneurysm [PDF]

European Heart Journal - Cardiovascular Imaging, 2014
A 35-year-old black man without cardiovascular risk factor presented with dizziness. Physical examination found an irregular cardiac rhythm and ECG revealed atrial fibrillation with a slow ventricular response. Brain magnetic resonance imaging (MRI) showed small and recent vertebrobasilar ischaemic strokes.

A Misleading Left Atrial Appendage

JACC: Case Reports, 2023
Left atrial appendage collapse is a relatively unusual echocardiographic finding. Although in post-cardiac surgery patients it may be an early sign of cardiac tamponade, and pericardiocentesis should be discussed, a conservative approach may be followed in cases secondary to viral infection without confusing it with a left atrial appendage thrombus ...

Genetic and Phenotypic Features of the Five Known Polyaminopathies: A Critical Narrative Review

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Polyaminopathies are a recently described family of rare genetic neurodevelopmental disorders. Polyaminopathies disrupt the biosynthesis of the primary polyamines: putrescine, spermidine, and spermine. Snyder–Robinson syndrome results from hemizygous loss‐of‐function variants in the spermine synthase (SMS) gene, resulting in decreased or ...

‘Twiddling’ of the pacemaker resulting in lead dislodgement [PDF]

, 2009
Twiddler’s syndrome is a rare condition in which patient manipulation of the pulse generator within its pocket may result in coiling of the lead and lead dislodgement, thereby causing pacemaker malfunction.
