背景：高强度聚焦超声球囊导管（HIFU‐BC）设计用于隔离开口（PV窦）外的肺静脉（PV）。该导管使用一个抛物线形CO2球囊（在水球囊后面），在球囊前方（平行于导管管身）聚焦一个直径为20、25或30 mm的超声环。本研究旨在测试HIFU‐BC用于房颤（AF）患者肺静脉窦隔离的安全性和有效性。
Background: A high‐intensity‐focused ultrasound balloon catheter (HIFU‐BC) is designed to isolate pulmonary veins (PV) outside the ostia (PV antrum). This catheter uses a parabolic CO2 balloon (behind water balloon) to focus a 20‐, 25‐, or 30‐mm diameter ring of ultrasound forward of the balloon (parallel to catheter shaft). The purpose of this study is to test the safety and efficacy of the HIFU‐BC for PV antrum isolation in patients with atrial fibrillation (AF).
