Ablation of atrial fibrillation

Current Cardiology Reports, 2006
Fueled by dissatisfaction with pharmacologic strategies to treat atrial fibrillation (AF), the results of basic and clinical investigation into the understanding of AF initiation and maintenance mechanisms, and the explosive development in catheter-based technologies, AF ablation has matured from a purely investigational technique to a preferred, safe,

P21‐Activated Kinase 2 as a Novel Target for Ventricular Tachyarrhythmias Associated with Cardiac Adrenergic Stress and Hypertrophy

Advanced Science, EarlyView.
Ca2+/calmodulin‐dependent kinase II (CaMKII) activation is likely driven by oxidative stress, particularly excessive reactive oxygen species (ROS) production. This study identifies P21‐activated kinase 2 (Pak2) as a novel regulator of ROS‐induced CaMKII activation and abnormal Ca2⁺ dynamics in acute adrenergic and chronic pressure‐overload stressed ...

Cognitive function in late‐stage HFpEF patients with tricuspid regurgitation undergoing transcatheter tricuspid valve intervention

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1323-1330, December 1, 2022., 2022
Abstract Objectives This study evaluates the impact of transcatheter tricuspid valve interventions (TTVI) on cognitive function (CF), quality of life (QOL), and exercise capacity in late‐stage heart failure with preserved ejection fraction (HFpEF) and relevant tricuspid regurgitation (TR).

Cryoballoon or Radiofrequency Ablation for Paroxysmal Atrial Fibrillation.

New England Journal of Medicine, 2016
BACKGROUND Current guidelines recommend pulmonary-vein isolation by means of catheter ablation as treatment for drug-refractory paroxysmal atrial fibrillation. Radiofrequency ablation is the most common method, and cryoballoon ablation is the second most

Transcatheter valve repair of tricuspid regurgitation with the PASCAL system: TriCLASP study 30‐day results

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1291-1299, December 1, 2022., 2022
Abstract Background Severe tricuspid regurgitation (TR) is independently associated with increased morbidity and mortality. Percutaneous transcatheter approaches may offer an alternative for patients not amenable to surgery. Methods TriCLASP is a prospective, single‐arm, multicenter European post‐market clinical follow‐up study (NCT04614402) to ...

ROS‐Activated Nanohydrogel Scaffolds with Multi‐Factors Controlled Release for Targeted Dual‐Lineage Repair of Osteochondral Defects

Advanced Science, EarlyView.
ROS‐activated nanohydrogels composite bilayer scaffolds are rationally designed for targted dual‐lineage repair of osteochondral defects. The as‐prepared nanohydrogel scaffolds provided 3D culture and induced dual‐lineage differentiation of BMSCs in vitro, efficiently inhibited early‐stage inflammation by rapidly releasing DS and improved cartilage and

Underweight and obesity are related to higher mortality in patients undergoing coronary angiography: The KARDIO invasive cardiology register study

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1242-1251, December 1, 2022., 2022
Abstract Background In patients with some cardiovascular disease conditions, slightly elevated body mass index (BMI) is associated with a lower mortality risk (termed “obesity paradox”). It is uncertain, however, if this obesity paradox exists in patients who have had invasive cardiology procedures.

Biophysical Characterization of α-Synuclein and Rotenone Interaction

Biomolecules, 2013
Previous studies revealed that pesticides interact with α-synuclein and accelerate the rate of fibrillation. These results are consistent with the prevailing hypothesis that the direct interaction of α-synuclein with pesticides is one of many suspected ...

GLS1‐Mediated Redundancy in Glutamate Accelerates Arterial Calcification via Activating NMDAR/Ca2+/β‐Catenin Pathway

Advanced Science, EarlyView.
GLS1 is a novel contributor to arterial calcification. GLS1‐catalyzed glutamate exerts the promoting effects on osteogenic reprogramming in arteries. NMDAR, a glutamate receptor, is also activated and overexpressed during arterial calcification.
