Data Augmentation for Automatic Identification of Spatiotemporal Dispersion Electrograms in Persistent Atrial Fibrillation Ablation Using Machine Learning.

Catheter ablation is increasingly used to treat atrial fibrillation (AF), the most common sustained cardiac arrhythmia encountered in clinical practice. A recent breakthrough finding in AF ablation consists in identifying ablation sites based on their spatiotemporal dispersion (STD). STD stands for a delay of the cardiac activation observed in intracardiac electrograms (EGMs) across contiguous leads.

[Amniotic band syndrome and facial malformations].

Amniotic band syndrome (ABS) is a collection of fetal congenital malformations affecting mainly the limbs, but also the craniofacial area. The pathogenic mechanism is still unclear. The facial malformations in ABS are multiple, polymorphous, and asymmetric.

[Soft tissue metastasis revealing an asymptomatic bronchial adenocarcinoma].

Skeletal muscle metastases from non-small-cell lung cancer are uncommon. We report a case of lung adenocarcinoma disclosed by metastatic dissemination to a forearm muscle. A 46-year-old man consulted for a painful mass of the right forearm.

[Prospective comparison between a clinical and biological score and ultrasonography for the diagnosis of benign or malignant hepatic lesions].

The purpose of this study was to compare ultrasound with a clinical and biological score to differentiate benign and malignant liver lesions. The study was carried out prospectively in 100 consecutive patients with liver masses of unknown origin. The accuracy of ultrasound and the score was 84% and 76%, respectively (P = 0.
