ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.

Pathophysiologic Consequences of Early Coarctation Stenting in a Longitudinal Porcine Model
ABSTRACT Background Novel stent technologies offer early intravascular treatment options for coarctation (COA). Mid‐to‐long‐term cardiovascular responses to early COA stent interventions are undefined. Aims We studied a porcine model of COA, with and without early stent implantation with serial dilation to adult aortic diameters, aiming to define ...

ABSTRACT Background A 3D electroanatomical mapping (3D‐EAM) visualized steerable sheath was designed to improve catheter placement and reduce radiation exposure during ablation, an established treatment for atrial fibrillation (AF). However, prospective randomized data comparing the procedural and clinical outcomes of visualized and non‐visualized ...

ABSTRACT Background Deflectable delivery systems have been introduced to enhance coaxial alignment and procedural efficacy during left atrial appendage occlusion (LAAO), yet randomized comparisons with conventional fixed‐curve systems are lacking. Aims The GUIDE‐LAAO trial evaluated whether the TruSteer deflectable delivery system is non‐inferior to ...

ABSTRACT Background Preprocedural planning with multislice computed tomography (MSCT) is an essential prerequisite for successful transcatheter aortic valve replacement (TAVR). However, preprocedural planning is time‐consuming and may contain clinically meaningful interobserver variability.

GAN‐LSTM‐3D: An efficient method for lung tumour 3D reconstruction enhanced by attention‐based LSTM
Abstract Three‐dimensional (3D) image reconstruction of tumours can visualise their structures with precision and high resolution. In this article, GAN‐LSTM‐3D method is proposed for 3D reconstruction of lung cancer tumours from 2D CT images. Our method consists of three phases: lung segmentation, tumour segmentation, and tumour 3D reconstruction. Lung

Gamma suppression correlates with thalamic stimulation therapeutic response in intractable epilepsy
Abstract Objective In patients with drug‐resistant epilepsy who undergo anterior nucleus of the thalamus (ANT) deep brain stimulation (DBS), efficacy is assessed months after therapy initiation and clinicians have no guidance when choosing stimulation parameters due to the lack of real‐time biomarkers.
