Investigating muscle architecture in static and dynamic conditions is essential to understand muscle function and muscle adaptations. Muscle architecture analysis, primarily through extended field-of-view ultrasound imaging, offers high reliability at rest but faces limitations during dynamic conditions. Traditional methods often involve "best fitting" straight lines to track muscle fascicles, leading to possible errors, especially with longer fascicles or those with nonlinear paths.

In several poorly documented cases, it was also selected in patients on dolutegravir. Given the widespread use of dolutegravir, further studies of S147G are required.

Objective: The aims of this study were to evaluate efficacy and safety of the pentaspline PFA catheter for PVI + LAPWI in patients with persistent AF undergoing an index ablation procedure and to compare 1-year outcomes of PVI + LAPWI with PFA vs CB-A.
Methods: All consecutive patients undergoing an index ablation for persistent atrial fibrillation (AF) at Universitair Ziekenhuis Brussel, Belgium, between 2021 and 2023 were retrospectively screened.
Background: A novel focal lattice-tip catheter allowing the delivery of either pulsed field (PF) or radiofrequency (RF) energy has recently received regulatory approval. The technology features a proprietary 3-dimensional electroanatomic mapping system.
Objective: We describe the first real-world and multicenter experience.
