经导管三尖瓣置换装置Lux-Valve与Lux-Valve Plus治疗重度三尖瓣反流患者的疗效比较
浙江大学学报. 医学版目的比较应用Lux-Valve与Lux-Valve Plus行经导管三尖瓣置换术（TTVR）治疗重度三尖瓣反流患者术后6个月的疗效。方法回顾性分析2019年8月至2023年11月因重度三尖瓣反流于空军军医大学第一附属医院行TTVR的28例患者的资料。按照置入瓣膜类型将患者分为Lux-Valve组和Lux-Valve Plus组，各14例。所有患者于TTVR术前及术后6个月行经胸超声心动图检查，比较患者TTVR术前与术后6个月以及Lux-Valve组与Lux-Valve Plus组各项指标。结果与Lux-Valve组比较，Lux-Valve Plus组术中出血量减少、术后住院时间缩短（均P<0.05）。TTVR后6个月，两组患者均无少量以上三尖瓣瓣内反流；Lux-Valve ...
