Persistence and Distortion of Electrical Activity in the LAA 5 Years After Endovascular Occlusion

JACC: Case Reports, 2020
This is the first report demonstrating persistence and distortion of electrical activity in the left atrial appendage 5 years after endovascular occlusion with a Watchman device. Electrical conduction is impaired providing an arrhythmogenic substrate for

Panoramic voltage‐sensitive optical mapping of contracting hearts using cooperative multiview motion tracking with 12 cameras

The Journal of Physiology, EarlyView.
Abstact figure legend A panoramic 3D optical mapping system was developed, enabling imaging of action potential waves across the entire strongly deforming ventricular surface of beating isolated hearts. The system comprises 12 high‐speed cameras and a soccerball‐shaped imaging chamber with 48 light‐emitting diodes (LEDs).

Interventional and surgical occlusion of the left atrial appendage

, 2017
With a steadily increasing prevalence, atrial fibrillation (AF) is the most common sustained cardiac arrhythmia worldwide and an independent risk factor for stroke caused by thromboembolic events.

Left Atrial Appendage Occlusion: British Cardiovascular Intervention Society and British Heart Rhythm Society Position Statement

Arrhythmia & Electrophysiology Review
Percutaneous left atrial appendage occlusion aims to reduce the risk of stroke in patients with AF, particularly those who are not good candidates for systemic anticoagulation.

Organ‐Specific and Conserved Regulatory Logic Orchestrates Gene Expression in the Embryonic Mesothelium

Advanced Science, Volume 13, Issue 34, 19 June 2026.
Integrated multi‐omic profiling maps the gene‐regulatory landscape of the coelomic mesothelium across heart, lung, and pancreas. A cardiac‐restricted regulatory program is uncovered in which TBX20 activates heart mesothelial (epicardial) cis‐regulatory elements, while MAF emerges as a conserved regulator of mesothelial identity.

Risk factors of incomplete endothelialization after left atrial appendage occlusion in patients with atrial fibrillation

Introduction We aimed to investigate the risk factors of incomplete device endothelialization (IDE) following left atrial appendage occlusion (LAAO) and provide a nomogram model for predicting the risks of IDE in patients with atrial fibrillation (AF ...

Left Atrial Appendage Occlusion as an Alternative to Anticoagulation

, 2021
Non-valvular atrial fibrillation is associated with a significantly increased risk of embolic stroke as a result of blood clots forming primarily in the left atrial appendage (LAA).

Outcomes of Left Atrial Appendage Occlusion in Heart Failure With Reduced Ejection Fraction

Catheterization and Cardiovascular Interventions, Volume 107, Issue 7, Page 2345-2352, June 1, 2026.
ABSTRACT Background Patients with heart failure with reduced ejection fraction (HFrEF) were excluded from major trials of left atrial appendage occlusion (LAAO). Aim The objective of this study was to describe this population and evaluate outcomes after LAAO in patients with and without HFrEF.

Acute Finger Ischemia Evaluated With Point‐Of‐Care‐Ultrasound and Diagnosed With Concurrent Polycythemia Vera, Antiphospholipid Syndrome, and Tobacco Use

Clinical Case Reports, Volume 14, Issue 6, June 2026.
We present a case of digital ischemia investigated and localized using point‐of‐care ultrasound (POCUS), in a patient that was subsrquently diagnosed with antiphospholipid syndrome and polycythemia vera concurrently, in the setting of active tobacco use. ABSTRACT In patients with undifferentiated extremity ischemia, point‐of‐care ultrasound (POCUS) can
