Velocity characteristics of atrial fibrillation sources determined by electrographic flow mapping before and after catheter ablation
Background: Electrographic-Flow-(EGF)-Mapping is a novel method to identify Atrial Fibrillation (AF) drivers. Sources of excitation during AF can be characterized and monitored. Objective: The aim of this study was to evaluate the correlation between velocity of EGF around a respective AF source and its spatial variability (SV) and stability (SST). Methods: 25 patients with AF were included in ...

Identification of active atrial fibrillation sources and their discrimination from passive rotors using electrographical flow mapping
Barbara Bellmann 1, Tina Lin 2, Peter Ruppersberg 3, Marit Zettwitz 1, Selma Guttmann 1, Verena Tscholl 1, Patrick Nagel 1, Mattias Roser 1, Ulf Landmesser 2, Andreas Rillig 4 Background: The optimal ablation approach for the treatment of persistent atrial fibrillation (AF) is still under debate; however, the identification and elimination of AF sources is thought to play a key role. Currently ...

First-in-man demonstration of 18-month spatiotemporal stability of active atrial fibrillation source detected by Electrographic Flow mapping in persistent atrial fibrillation
Keywords: atrial fibrillation, catheter ablation, mapping, atrial fibrillation, source, electrographic flow Introduction: Advanced mapping methods for atrial fibrillation (AF) have previously suffered from poor spatiotemporal stability. Electrographic flow (EGF) mapping is a novel technique using computer vision and optical flow smoothing algorithms to avoid this issue. The aim of this ...

Huateng Pharma Supplies Some Intermediates of CDK4/6 Inhibitors for Treatment of Advanced Breast Cancer
Breast cancer is the most frequent cancer among women, impacting 2.1 million women each year, and also causes the greatest number of cancer-related deaths among women. In 2018, it is estimated that 627,000 women died from breast cancer – that is approximately 15% of all cancer deaths among women. While breast cancer rates are higher among women in more developed regions, rates are ...

Peptides for Osteoporosis Research
Introduction to OsteoporosisOsteoporosis is a systemic multi-causal skeletal disease that is prone to fractures due to changes in systemic bone mass and microstructure of bone tissue, resulting in increased bone fragility. Osteoporosis is a type of disease that is difficult to cure. According to the etiology, it can be divided into primary osteoporosis, secondary osteoporosis and idiopathic ...

Conceptual Considerations for Device-Based Therapy in Acute Decompensated Heart Failure
Abstract Acute decompensated heart failure remains the most common cause of hospitalization in older adults, and studies of pharmacological therapies have yielded limited progress in improving outcomes for these patients. This has prompted the development of novel device–based interventions, classified mechanistically based on the way in which they intend to improve central hemodynamics, ...
