The safety of direct transeptal puncture using a radiofrequency guidewire combined with a 17Fr pulsed field ablation sheath

Scientific Reports
Transseptal puncture (TSP) is widely used in catheter-based cardiac interventions to gain left atrial (LA) access, but its workflow has remained largely unchanged and is still a source of serious complications.

Polymorphism in alpha-synuclein oligomers and its implications in toxicity under disease conditions

Frontiers in Molecular Biosciences, 2022
The major hallmark of Parkinson’s disease (PD) is represented by the formation of pathological protein plaques largely consisting of α-synuclein (αSN) amyloid fibrils.

Dynamic fibrils in H-alpha and C IV [PDF]

Astron.Astrophys.460:309-316,2006, 2007
Aim: To study the interaction of the solar chromosphere with the transition region, in particular active-region jets in the transition region and their relation to chromospheric fibrils. Methods: We carefully align image sequences taken simultaneously in C IV with the Transition Region and Coronal Explorer and in H-alpha with the Swedish 1-m Solar ...

Atrial fibrillation

Australian Journal of General Practice, 2019
Abstract Atrial fibrillation (AF) is the commonest cardiac arrhythmia in hospitalized patients, with an increasing incidence with age and an epidemic increase projected for the next 10 years. Therapy of AF has several goals: to decrease mortality (mainly due to cardiovascular diseases), stroke rate, ventricular deterioration, and heart ...

Incidence, duration, pattern, and burden of de novo atrial arrhythmias detected by continuous ECG monitoring using an implantable loop recorder following ablation of the cavotricuspid isthmus

Cardiovascular Digital Health Journal, 2020
Background: Following cavotricuspid isthmus (CTI) ablation, many patients with atrial flutter (AFL) are diagnosed with atrial fibrillation (AF). The incidence, duration, pattern, and burden of AF remain undefined.

Apixaban versus warfarin in patients with atrial fibrillation.

New England Journal of Medicine, 2011
BACKGROUND Vitamin K antagonists are highly effective in preventing stroke in patients with atrial fibrillation but have several limitations. Apixaban is a novel oral direct factor Xa inhibitor that has been shown to reduce the risk of stroke in a ...

Bruton tyrosine kinase inhibitors in the management of Waldenström macroglobulinemia

American Journal of Hematology, Volume 98, Issue 2, Page 338-347, February 2023., 2023
Abstract Bruton tyrosine kinase (BTK) inhibitors have taken a central role in the management of patients with Waldenström macroglobulinemia and are the only agents approved by the Food and Drug Administration (FDA) to treat these patients. Although associated with high rates of durable responses, unmet needs with BTK inhibitor therapy include ...

Catheter ablation of atrial fibrillation in patients with diabetes mellitus

Heart Rhythm O2, 2020
Background: Diabetes mellitus (DM) is an independent risk factor for atrial fibrillation (AF). Few studies have compared clinical outcomes after catheter ablation between patients with and those without DM.
