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. …
