单纯室间隔缺损(VSD)是一种常见的先天性心脏病(先心病),约占所有先心病的10%~20%。外科修补术一直是治疗单纯VSD的传统方法,虽然技术已经比较成熟,但需体外循环,手术创伤大,且住院时间长。近年来,随着Amplatzer VSD封堵器的研制成功,使得经导管VSD封堵术(TCVSD)的广泛开展成为 Simple ventricular septal defect (VSD) is a common congenital heart disease (congenital heart disease), accounting for about 10% to 20% of all congenital heart disease. Surgical repair has always been the traditional treatment of VSD alone, although the technology has been more mature, but need extracorporeal circulation, surgical trauma, and hospitalization for a long time.
