摘 要:生物可吸收封堵器的应用有望降低传统金属封堵器并发症的风险.之前研制的生物可吸收封堵器存在不完全降解的局限性并导致新的并发症,因此目前尚未有相关产品获批上市.本研究使用了一种新型完全可吸收封堵器,旨在探索完全可吸收封堵器治疗室间隔缺损的疗效和安全性.从2019年4月到2020年1月,本研究在七个医学中心入组125名膜周部室间隔缺损患者,经筛查后108名患者被纳入研究并随机分为植入生物可吸收封堵器实验组和金属封堵器组.所有受试者均成功植入封堵器并完成24个月的随访.生物可吸收封堵器组患者经胸超声心动图显示高亮回声在24个月内逐渐消失,说明可吸收封堵器在体内实现完全降解.对比金属封堵器,实验组器械相关心律失常发生率(5.56%vs.14.81%,P=0.112)和持续传导阻滞发生率(0/54 vs.6/54,P=0.036)显著降低.本研究提示新型完全可吸收封堵器可以在单纯超声引导下实现成功植入,同时降低术后永久性心律失常的发生率.Although the use of bioabsorbable occluder is expected to reduce the risk of metal occluder-related complications,it has not been approved due to incomplete degradation and new complications.Novel fully bioabsorbable occluders were designed to overcome such limitations.The aim of this study was to investigate the efficacy and safety of a fully biodegradable occluder in patients with ventricular septal defects.125 patients with perimembranous ventricular septal defect(VSD)larger than 3 mm were screened from April 2019 to January 2020 in seven centers.108 patients were enrolled and randomized into the bioabsorbable occluder group(n=54 patients)and nitinol occluder group(n=54).A non-inferiority design was utilized and all patients underwent transcatheter device occlusion.Outcomes were analyzed with a 24-month follow-up.All patients were successfully implanted and completed the trial.No residual shunt>2 mm was observed during follow-up.Transthoracic echocardiography showed a hyperechoic area corresponding to the bioabsorbable occluder which decreased primarily during the first year after implantation and disappeared within 24 months.Postprocedural arrhythmia was the only occluderrelated complication with an incidence of 5.56%and 14.81%for the bioabsorbable and nitinol groups,respectively(P=0.112).The incidence of sustained conduction block was lower in the bioabsorbable occluder group(0/54 vs.6/54,P=0.036)at 24-month follow-up.In conclusion,the novel fully bioabsorbable occluder can be successfully and safely implanted under echocardiography guidance and reduce he incidence of sustained postprocedural arrythmia.The efficacy and safety of this fully biodegradable occluder are non-inferior to that of a traditional nitinol one.
