Excerpt

Pulsed field ablation (PFA) is a novel nonthermal catheter ablation for atrial fibrillation (AF) [1]. However, ablation of the right inferior pulmonary vein (RIPV) using a pentaspline catheter (Farawave, Boston Scientific, Marlborough, MA, USA) is sometimes challenging. Tight spaces may cause spline bunching, leading to low resistance, overcurrent, and ineffective energy release. Excessive bunching can cause a “cobra-shaped” spline, requiring stowing and rotation in a sheath or removal from the body, which increases the risk of air embolism [2]. To address these concerns, we propose a simple method to efficiently position a pentaspline catheter on the RIPV antrum, facilitating a smooth ablation procedure while effectively avoiding catheter deformation. …

Keynote webinar | Spotlight on medication adherence

  • Webinar | 27-06-2024 | 18:00 (CEST)

Medication non-adherence is a major barrier to effective healthcare delivery; half of all patients do not follow their doctor’s recommendations or treatment plan.

Our experts explain the fundamentals with a practical discussion of how to manage non-adherence in two common scenarios: hypertension and asthma control.
