Wide antral circumferential vs. ostial pulmonary vein isolation using pulsed field ablation—the butterfly effect

Frontiers in Cardiovascular Medicine, 2023
BackgroundWide antral circumferential ablation (WACA) in comparison to ostial pulmonary vein (PV) isolation (PVI) has been attributed with improved rhythm outcome.

Left Atrial Posterior Wall Isolation in the Treatment of Atrial Fibrillation [PDF]

, 2020
The optimal approach for the ablation of persistent atrial fibrillation is undefined. Left atrial posterior wall isolation (LAPWI) is a promising lesion set, based on techniques for surgical AF ablation. The left atrial posterior wall can be isolated via

Effect of epicardial fat volume on outcomes after left atrial posterior wall isolation in addition to pulmonary vein isolation in patients with persistent atrial fibrillation

Frontiers in Cardiovascular Medicine, 2022
BackgroundGreater epicardial adipose tissue (EAT) is related to higher recurrences after atrial fibrillation catheter ablation (AFCA). We investigated the effects of posterior wall box isolation (POBI) in conjunction with circumferential pulmonary vein ...

Hybrid Ablation of Nonparoxysmal Atrial Fibrillation: The Convergent and Totally Thoracoscopic Approaches

Reviews in Cardiovascular Medicine, 2022
Nonparoxysmal atrial fibrillation continues to challenge electrophysiologist and surgeons alike. Stand-alone endocardial catheter ablation has resulted in less than satisfying results, and while the on-pump Cox-Maze surgery has excellent results, the ...

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Longstanding Persistent Atrial Fibrillation Ablation: How Do You Perform It?

Journal of Cardiac Arrhythmias, 2020
Longstanding-persistent atrial fibrillation is one of the most challenging arrhythmias to treat. While radiofrequency catheter ablation is highly effective in paroxysmal atrial fibrillation, pulmonary vein antral isolation (including posterior wall ...

Posterior wall substrate modification using optimized and contiguous lesions in patients with atrial fibrillation

, 2020
\(\bf Background:\) Radiofrequency (RF) linear ablation at the left atrial (LA) roof and bottom to isolate the LA posterior wall using contiguous and optimized RF lesions was evaluated.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Natural History of Arrhythmia After Successful Isolation of Pulmonary Veins, Left Atrial Posterior Wall, and Superior Vena Cava in Patients With Paroxysmal Atrial Fibrillation: A Multi‐Center Experience

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background We evaluated long‐term outcome of isolation of pulmonary veins, left atrial posterior wall, and superior vena cava, including time to recurrence and prevalent triggering foci at repeat ablation in patients with paroxysmal atrial fibrillation ...
