Purpose: Atrial fibrillation (AF) is the most common chronic cardiac arrhythmia that increases the risk of stroke, primarily due to thrombus formation in the left atrial appendage (LAA). Left atrial appendage occlusion (LAAO) devices offer an alternative to oral anticoagulation for stroke prevention. However, the complex and variable anatomy of the LAA presents significant challenges to device design and deployment.

Reaching competency in congenital heart surgery (CHS) requires lengthy and rigorous training. Due to patient safety, time limitations, and procedural complexity, the intraoperative setting is not ideal for technical practice. Surgical simulation using synthetic, biological, or virtual models is an increasingly valuable educational tool for technical training and assessment.

This contribution details a new high-fidelity finite element analysis (FEA) methodology for the investigation of the effect of the graft size on the pressure distribution developing at the calcaneocuboid joint after the Evans osteotomy procedure. The FEA model includes all 28 bones of the foot up to the distal end of fibula and tibia as well as soft tissues, tendons, and muscles. The developed FEA model was validated by comparing the in-vivo pressure distribution on the foot plantar with the in-silico results, resulting in a low deviation equal to 7.

Use of an observer tool to enhance learning of anaesthesia resident's non-technical skills during high-fidelity simulation: a randomised controlled trial.

Centre de Simulation LabForSIMS, Département de Recherche et Innovation Pédagogique en Santé, Faculté de Médecine, Université Paris Saclay, Le Kremlin-Bicêtre, 94275, France.

Background: The use of an observer tool (OT) has been shown to improve learning of technical skills through observation in simulation. The objective was to assess the impact of a non-technical OT on anaesthesia residents' learning of non-technical skills (NTS) during simulation.

Methods: After consent, residents were randomised into 2 groups: OT+ (with an OT based on NTS to be systematically completed during observation of others) and OT- (without OT).
