研究目的: |
本研究旨在评价经导管球囊房间隔造口术(Balloon Atrial Septostomy, BAS)在终末期肺动脉高压及肺动脉高压危象患者中的生存及预后改善效果。本研究为多中心、前瞻性、随机对照试验,重点评估BAS对患者24个月无肺移植生存率的影响,同时观察其对血流动力学、右心结构与功能重构、临床症状及运动耐量的改善,以及对术后1年和3年全因死亡率的影响。本研究亦将系统评估BAS的围手术期及远期安全性。 |

|
Objectives of Study: |
This study aims to evaluate the survival and prognostic benefits of balloon atrial septostomy (BAS) in patients with end-stage pulmonary arterial hypertension or PAH crisis. In this multicenter, prospective, randomized controlled trial, the primary focus is to assess transplant-free survival at 24 months. Additionally, the study will examine improvements in hemodynamics, right ventricular structure and function, clinical symptoms, and exercise capacity, as well as impacts on 1-year and 3-year all-cause mortality. The peri-procedural and long-term safety profile of BAS will also be systematically evaluated. |

盲法: |
本试验为开放标签设计,未对受试者、干预实施者(操作医师)或结局评估者设置盲法。这是由于试验组(经导管球囊房间隔造口术)与对照组(充分联合靶向药物治疗)的干预措施性质差异巨大,在技术上无法对参与者或操作医师设盲。 |
|
Blinding: |
This trial was an open-label study. No blinding was applied to the subjects, intervention providers (operating physicians), or outcome assessors. This was because the nature of the interventions differed fundamentally between the trial group (transcatheter balloon atrial septostomy) and the control group (full combined targeted drug therapy), making it technically impossible to blind the participants or the operating physicians. |
