Left atrial appendage closure (LAAC) devices can be inadvertently released into unfavorable locations, which may allow them to migrate to a different position within the left atrial appendage or embolize from the heart into the aorta. In such instances, it can be challenging to remove the LAAC device. Here, we present two cases in which patients with atrial fibrillation experienced LAAC device exposure at an inappropriate site because of interventional operator error and device mismatch: (a) the LAAC device was dislodged into the aortic arch and retrieved percutaneously from the femoral artery route, and (b) in the left atrium, which was dislodged into the left atrium and retrieved atrial transseptal puncture of the femoral vein.

Background: Sequential application of radiofrequency with pulsed field (PF) ablation may increase lesion depth while preserving the advantages of PF. The study's aim was to determine lesion dimensions of sequential, colocalized radiofrequency and PF ablation.
Methods: A preclinical study using swine (n=4) performed lesions in the right/left ventricles.

Background: Areas of conduction disorders play an important role in both initiation and perpetuation of AF and can be recognized by specific changes in unipolar potential morphology. For example, EGM fractionation may be caused by asynchronous activation of adjacent cardiomyocytes because of structural barriers such as fibrotic strands. However, it is unknown whether there are sex differences in unipolar potential morphology.

Atrial fibrillation (AF) is the most common tachyarrhythmia and seriously affects human health. Key targets of AF bioinformatics analysis can help to better understand the pathogenesis of AF and develop therapeutic targets. The left atrial appendage tissue of 20 patients with AF and 10 patients with sinus rhythm were collected for sequencing, and the expression data of the atrial tissue were obtained.

We report a case of persistent consciousness disturbance due to non-convulsive status epilepticus (NCSE) following a successful mechanical thrombectomy (MT). A 98-year-old female with atrial fibrillation presented with impaired consciousness and right hemiparesis 6 hrs after her last known well state. Magnetic resonance angiography revealed occlusion of the left internal carotid artery, necessitating MT to achieve complete recanalisation.

Objective: Chronic Chagas Cardiomyopathy (CCC) carries a high risk of embolic events due to structural changes in the left ventricle and frequent conduction disorders. However, there is limited data on anticoagulant prescription patterns and factors influencing the use of direct oral anticoagulants (DOACs) in these patients. This study aims to characterize CCC patients based on the anticoagulant therapy received and identify factors associated with DOACs use.
