Prospective Randomized Evaluation of High Power during CLOSE-guided Pulmonary Vein Isolation: The POWER-AF Study.

Circulation: Arrhythmia and Electrophysiology, 2020
Background - CLOSE-guided atrial fibrillation (AF) ablation is based on contiguous (inter-tag distance ≤6mm), optimized (Ablation Index (AI) >550 anteriorly and >400 posteriorly) point-by-point radiofrequency (RF) lesions.

Excessive MYC Orchestrates Macrophages induced Chromatin Remodeling to Sustain Micropapillary‐Patterned Malignancy in Lung Adenocarcinoma

Advanced Science, Volume 12, Issue 12, March 27, 2025.
Song et al. integrates an evaluating system to characterize malignancy of micropapillary (MP)‐pattern lung adenocarcinoma in vivo or in vitro. They have discovered that intrinsic MYC redundancy expression combined with extrinsic M2‐like macrophage jointly mediate MP‐pattern malignancy.

Left atrial appendage (LAA) electrical isolation by Maze‐like catheter substrate modification in presence of LAA‐occluder device: A case report

Clinical Case Reports, 2020
Maze‐like linear substrate modification in atrial fibrillation patients nonresponders to pulmonary vein isolation represents a feasible technique to gain left atrial appendage electrical isolation even in the presence of a Watchman occluder device.

Vision Transformers increase efficiency of 3D cardiac CT multi-label segmentation [PDF]

arXiv, 2023
Accurate segmentation of the heart is essential for personalized blood flow simulations and surgical intervention planning. Segmentations need to be accurate in every spatial dimension, which is not ensured by segmenting data slice by slice. Two cardiac computed tomography (CT) datasets consisting of 760 volumes across the whole cardiac cycle from 39 ...

Pulmonary Vein Nonconduction

JACC: Clinical Electrophysiology, 2016
Durable isolation following pulmonary vein (PV) ablation may not be necessary for effective suppression of atrial fibrillation (AF) in certain patients with AF. However, most patients are thought to benefit from durable PV isolation, because PV reconnection seems to by and large underlie ...

The Placenta Regulates Intrauterine Fetal Growth via Exosomal PPARγ

Advanced Science, Volume 12, Issue 15, April 17, 2025.
The placenta expresses much higher levels of PPARγ than fetal adipose tissue. Trophoblastic exosomes transport PPARγ into fetal preadipocytes via fetoplacental circulation and thus regulate adipogenic genes distinct from endogenous PPARγ. Compromised placental PPARγ leads to fetal adipogenesis deficiency and intrauterine growth restriction, reversible ...

Single Ectopy-Triggering Ganglionated Plexus Ablation Without Pulmonary Vein Isolation Prevents Atrial Fibrillation

JACC: Case Reports, 2020
A 58-year-old woman with drug-refractory symptoms of paroxysmal atrial fibrillation (AF) was referred for AF ablation. A single site of ganglionated plexus triggering pulmonary vein ectopy and AF was ablated, without pulmonary vein isolation.

Safety and efficacy of early radiofrequency catheter ablation in patients with paroxysmal atrial fibrillation complicated with amiodarone-induced thyrotoxicosis [PDF]

, 2016
Background: Amiodarone is an antiarrhythmic drug that is frequently used to control atrial fibrillation (AF). Many patients with AF are afraid of the risk of ablation and take amiodar­one, some patients develop amiodarone-induced thyrotoxicosis (AIT ...
