The effect of the pericardial patching exclusion technique for left atrial appendage closure on postoperative reopening rate

BMC Cardiovascular Disorders
Background The left atrial appendage (LAA) is the primary source of cardiogenic embolism in atrial fibrillation patients. Traditional LAA closure methods have shown suboptimal clinical outcomes.

Bilateral atrial appendage aneurysms associated with atrial fibrillation. [PDF]

, 2014
Aneurysm of the left atrial appendage is an extremely rare anomaly. We describe the case of a 68-year-old man who presented with palpitation and was found to have a very large aneurysm located near the left atrial appendage on routine echocardiography ...

Conjugated Porphyrin Polymer With Superior Charge Transfer for Photodynamic‐Immunomodulatory Prevention of CIED Infection in Diabetes

Advanced Healthcare Materials, EarlyView.
Under NIR irradiation, PTCPP generates ROS to eliminate MRSA biofilms and promote M1 macrophage polarization for phagocytosis. After bacterial clearance, the material is phagocytosed by macrophages, shifting their polarization to M2 phenotype via metabolic reprogramming, which synergistically enhances anti‐infection therapy and wound healing.

Therapeutic Dilemma of Natural Watchman: Congenital Absence of the Left Atrial Appendage

Case Reports in Cardiology, 2018
Congenital absence of the left atrial appendage is a rare congenital cardiac anomaly which is usually an incidental finding. We present a rare case of congenital absence of the left atrial appendage in a 77-year-old female patient with atrial ...

A Geometrically Transient Platform for Bioelectronic Implants

Advanced Materials, EarlyView.
Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.

Left atrial appendage size is a marker of atrial fibrillation recurrence after radiofrequency catheter ablation in patients with persistent atrial fibrillation

Clinical Cardiology, 2021
There are no consistently confirmed predictors of atrial fibrillation (AF) recurrence after catheter ablation. Therefore, we aimed to study whether left atrial appendage volume (LAAV) and function influence the long‐term recurrence of AF after catheter ...

Left atrial appendage closure with the Amplatzer cardiac plug in patients with atrial fibrillation

, 2012
Percutaneous left atrial appendage closure (LAAC) has emerged as an alternative to oral anticoagulation (OA) for prevention of thromboembolic stroke in patients with non-valvular atrial fibrillation (NVAF)

Cysteine Redox State Governs the Condensation Pathway of Hendra Virus W Protein and Differentially Impacts Type I IFN and NF‐κB Signaling

Advanced Science, EarlyView.
The cysteine redox state of the Hendra virus W (WHeV) protein controls assembly into fibrils or amorphous aggregates, with residues 2–29 required for fibrillation. In cells, WHeV forms different types of nuclear condensates. Impaired ability to form redox‐sensitive, non‐filamentous condensates reduces WHeV inhibition of the NF‐κB pathway, while it ...

The long‐term efficacy and safety of combining ablation and left atrial appendage closure: A systematic review and meta‐analysis

Cardiovascular Electrophysiology, 2021
Combined ablation and left atrial appendage closure (LAAC) is an alternative for atrial fibrillation patients with a high risk of stroke. However, the long‐term outcomes of this combined procedure remain elusive.
