目的 分析经导管三尖瓣置换术(transcatheter tricuspid valve replacement,TTVR)治疗电极导线相关三尖瓣反流(tricuspid regurgitation,TR)的临床疗效.方法 回顾性纳入2020年6月-2021年8月国内9家医疗单位接受LuX-Valve TTVR的重度TR患者.根据术前是否接受植入式心脏电子装置(cardiac implantable electronic device,CIED)分为CIED组和非CIED组.手术成功定义为瓣膜安全植入,输送器完整退出.预后改善定义为TR等级下降至≤2+级,心功能改善≥2个等级.比较两组患者手术成功率及术后预后情况.结果 共纳入190例患者,其中男50例、女140例,平均年龄(66.2±7.8)岁.CIED组29例,非CIED组161例.CIED组28例患者植入永久起搏器,1例患者植入心律转复除颤器.两组患者术前心功能分级、TR程度、左心室射血分数、三尖瓣环收缩期位移、心脏风险评分差异均无统计学意义(P＞0.05).术后所有患者TR降低至≤2+级,两组瓣周漏发生率差异无统计学意义(P=0.270),CIED组患者术后复查CT可见瓣膜在位,电极导线无明显挤压、扭曲、偏移.两组患者在院死亡率分别为10.3％和1.9％,差异有统计学意义(P=0.047).此外,两组患者术后心功能改善情况、随访1年和2年死亡率差异均无统计学意义(P＞0.05).结论 TTVR对CIED植入患者可行且安全有效,电极导线对治疗效果无显著影响.
Clinical efficacy of transcatheter tricuspid valve replacement in cardiac implantable electronic lead-related tricuspid regurgitation:A multi-center retrospective cohort study
Objective To analyze the clinical efficacy of transcatheter tricuspid valve replacement(TTVR)in cardiac implantable electronic lead-related tricuspid regurgitation(TR).Methods The patients with severe TR who underwent LuX-Valve TTVR in 9 Chinese medical centers from June 2020 to August 2021 were retrospectively enrolled.They were divided into a cardiac implantable electronic device(CIED)group and a non-CIED group based on whether they had pre-existing CIED implantation.Success of the procedure was defined as safe implantation of the LuX-Valve and complete withdrawal of the delivery system.Prognostic improvement was defined as a decrease of TR grade to≤2+and an improvement of cardiac function by≥ 2 grades.Surgical success and postoperative prognosis were compared between the two groups.Results A total of 190 patients were collected,including 50 males and 140 females with a mean age of 66.2±7.8 years.There were 29 patients in the CIED group,and 161 patients in the non-CIED group.In the CIED group,28 patients were implanted with a permanent pacemaker and 1 patient with a cardioverter-defibrillator.Preoperative New York Heart Association(NYHA)cardiac function class,TR degree,left ventricular ejection fraction,tricuspid annular plane systolic excusion,and cardiac risk scores were comparable between the two groups(P＞0.05).Postoperative TR was reduced to≤2+in all patients,and there was no statistical difference in the incidence of perivalvular leakage between the two groups(P=0.270).Postoperative CT of CIED patients showed the valve was in place,and the lead was not extruded,twisted,or deflected.The in-hospital mortality of the two groups were 10.3％and 1.9％,respectively,and the difference was statistically significant(P=0.047).In addition,there was no statistical difference between the two groups in terms of postoperative improvement of cardiac function and mortality in the 1-and 2-year follow-up.Conclusion TTVR is feasible,safe,and effective in patients with CIED implantation,and the pre-existing lead has no significant effect on the clinical efficacy.
