The safety of direct transeptal puncture using a radiofrequency guidewire combined with a 17Fr pulsed field ablation sheath.

Transseptal puncture (TSP) is widely used in catheter-based cardiac interventions to gain left atrial (LA) access, but its workflow has remained largely unchanged and is still a source of serious complications. Pulsed field ablation (PFA) for pulmonary vein isolation (PVI) has been shown to be at least comparable with radiofrequency ablation (RFA) in terms of safety and efficacy. However, PFA catheter delivery to the LA typically requires a standard TSP and an over the wire sheath exchange which can limit workflow and lengthen procedure time-a shorter procedure time being a proposed advantage of PFA over RFA.

: Selective cryolipolysis is a widely used aesthetic procedure that cools subcutaneous adipose tissue to temperatures as low as to induce fat cell destruction. However, real-time monitoring techniques are lacking, limiting the ability to optimize safety and efficacy. Traditional imaging methods either fail to provide adequate penetration depth or lack the resolution necessary for visualizing subcutaneous fatty tissue dynamics.

Background: Grasping and manipulating objects requires humans to adapt both grip and manipulation forces. When handling an object with both hands, the additional degrees of freedom introduce more levels to the redundancy of the object manipulation since we can distribute the contribution of the grip and manipulation forces between hands.
Methods: In this study, we investigated the forces produced by both hands during coupled bimanual manipulation of a needle object in a virtual environment.

Purpose: Lung cancer remains the leading cause of cancer death. This has brought about a critical need for managing peripheral regions of interest (ROIs) in the lungs, be it for cancer diagnosis, staging, or treatment. The state-of-the-art approach for assessing peripheral ROIs involves bronchoscopy.
