Different antithrombotic strategies after left atrial appendage closure with the LACbes occluder: protocol of the DAAL trial

BMJ Open
Introduction The purpose of this study is to evaluate the safety and efficacy of two different antithrombotic strategies, dual antiplatelet therapy (DAPT, aspirin and ticagrelor) and direct oral anticoagulant (DOAC, rivaroxaban), after left atrial ...

Echocardiography‐Assisted Stenting of the Ductus Venosus in Infracardiac TAPVC: Report of a New Technique and Review of the Literature

Catheterization and Cardiovascular Interventions, Volume 108, Issue 1, Page 214-220, July 1, 2026.
ABSTRACT Neonates with infracardiac total anomalous pulmonary venous connection (TAPVC) frequently require urgent treatment. If surgical repair is contraindicated due to extreme prematurity, interventional stenting of the ductus venosus (DV) has been introduced successfully to postpone surgery.

Severe coronary artery spasm during left atrial appendage closure plus catheter ablation for atrial fibrillation: case presentation

BMC Cardiovascular Disorders, 2022
Background Left atrial appendage closure (LAAC) combined with radiofrequency catheter ablation (RFCA) as a hybrid procedure is commonly performed to treat atrial fibrillation (AF). Although this treatment carries a low risk of coronary artery spasm (CAS),

Systematic Analysis of Gene Expression Differences between Left and Right Atria in Different Mouse Strains and in Human Atrial Tissue [PDF]

, 2011
Background: Normal development of the atria requires left-right differentiation during embryonic development. Reduced expression of Pitx2c (paired-like homeodomain transcription factor 2, isoform c), a key regulator of left-right asymmetry, has recently ...

Recurrent Ischemic Stroke Caused by a Residual PFO Shunt After Surgical Repair: Three‐Dimensional Transesophageal Echocardiography‐Guided Localization and Transcatheter Closure

Echocardiography, Volume 43, Issue 7, July 2026.
Residual shunting after surgical PFO closure may cause recurrent paradoxical embolism. Three‐dimensional transesophageal echocardiography combined with microbubble testing and multiplanar reconstruction enabled precise localization of an elusive residual shunt and guided successful transcatheter closure.

Virtual left atrial appendage occlusion in paroxysmal atrial fibrillation during sinus rhythm predicts variable reductions in blood stasis

The Journal of Physiology, Volume 604, Issue 13, Page 5342-5354, 1 July 2026.
Abstract figure legend Stasis before and after left atrial appendage occlusion (LAAO) in participants with high stasis and low stasis. Stasis is predominantly located in LAA and reduced after LAAO. But in the participant with high stasis, stasis remains close to the occlusion site, indicating a potential risk for device related thrombi.
