摘　　要：目的探讨保留二尖瓣瓣下结构二尖瓣膜置换手术对心功能、瓣膜功能及并发症的影响。方法选取2019年8月至2022年7月在苏州大学附属第一医院行保留二尖瓣瓣下结构二尖瓣膜置换手术患者84例作为观察组,同时选取同期未保留二尖瓣瓣下结构二尖瓣膜置换手术患者68例作为对照组,比较两组手术指标和并发症,以及手术前后心功能指标、二尖瓣口血流动力学参数。结果观察组和对照组手术时间、体外循环时间、主动脉阻断时间、术后机械通气时间、ICU滞留时间和术后住院时间比较差异无统计学意义(P>0.05);观察组术后1、3和6个月时左室收缩末期内径(LVESD)、左室舒张末期内径(LVEDD)明显低于对照组(P<0.05),左室短轴缩短率(LVFS)明显高于对照组(P<0.05);观察组和对照组术后1、3和6个月时左室射血分数(LVEF)比较差异无统计学意义(P>0.05);观察组和对照组术后1、3和6个月时二尖瓣口峰值流速(Vmax)、最大跨瓣压差(PGmax)和平均跨瓣压差(PGmean)比较差异无统计学意义(P>0.05);观察组和对照组术后1、3和6个月时肌酸激酶同工酶(CK-MB)和N末端前体脑利钠肽(NT-proBNP)比较差异无统计学意义(P>0.05);观察组和对照组术后并发症发生率比较差异无统计学意义(P>0.05)。结论保留二尖瓣瓣下结构二尖瓣膜置换手术有助于心脏结构保护、改善患者心功能,同时与不保留二尖瓣瓣下结构手术相比,二尖瓣口血流参数及并发症无明显差异。Objective To investigate the effects and complications of mitral valve membrane replacement surgery with preservation of mitral valve subvalvular structure on cardiac and valve function.Methods A total of 84 patients receiving mitral valve membrane replacement surgery with preserved mitral valve subvalvular structure in the First Affiliated Hospital of Soochow University from August 2019 to July 2022 were selected as the observation group,and 68 patients receiving mitral valve membrane replacement surgery without preservingmitral valve subvalvular structure were selected as the control group.The surgical indicators,comorbidities,preoperative and postoperative cardiac function,and mitral valve hemodynamic parameters were compared between the two groups.Results There was no statistically significant difference between the observation group and the control group in terms of surgical history,extracorporeal circulation time,aortic occlusion time,postoperative mechanical ventilation time,ICU retention time,and postoperative hospitalization time(P>0.05).At 1,3,and 6 months after surgery,the left ventricular end systolic diameter(LVESD)and left ventricular end diastolic diameter(LVEDD)in the observation group were significantly lower than those in the control group(P<0.05),while the left ventricular short axis shortening rate(LVFS)was significantly higher than that in the control group(P<0.05).There was no statistically significant difference in left ventricular ejection fraction(LVEF)between the observation group and the control group at 1,3,and 6 months after surgery(P>0.05).There was no statistically significant difference(P>0.05)in the peak mitral valve velocity(Vmax),maximum pressure gradient difference(PGmax),and mean pressure gradient difference(PGmean)between the observation group and the control group at 1,3,and 6 months after surgery.There was no statistically significant difference in creatine kinase isoenzyme(CK-MB)and N-terminal precursor brain natriuretic peptide(NT-proBNP)between the observation group and
