目的:评价改良扩大Morrow手术(室间隔心肌切除术)治疗青少年肥厚型梗阻性心肌病(HOCM)的早期手术疗效。方法:回顾性分析我院2011年至2015年改良扩大Morrow手术治疗29例青少年(≤21岁)HOCM患者的临床资料,评价早期手术疗效。术前、术后...目的:评价改良扩大Morrow手术(室间隔心肌切除术)治疗青少年肥厚型梗阻性心肌病(HOCM)的早期手术疗效。方法:回顾性分析我院2011年至2015年改良扩大Morrow手术治疗29例青少年(≤21岁)HOCM患者的临床资料,评价早期手术疗效。术前、术后超声心动图检查比较左心房前后径、左心室舒张末期内径、左心室射血分数、室间隔厚度、左心室流出道峰值压差、二尖瓣收缩期前向运动征和二尖瓣反流分级变化,同时抽血检测术前、术后血浆N末端B型利钠肽原水平变化,采用纽约心脏协会心功能分级评估心功能。结果:本组患者中,接受单纯改良扩大Morrow手术者17例(58.6%),同时行冠状动脉旁路移植术者8例(27.6%)。与术前比较,改良扩大Morrow手术后患者的室间隔厚度显著减小[(24.6±6.8)mm vs(16.9±7.1)mm,P<0.01],左心室流出道峰值压差明显降低[(68.8±15.7)mm Hg(1 mm Hg=0.133 k Pa)vs(10.7±4.2)mm Hg,P<0.01],二尖瓣反流明显减轻[(1.7±1.3)级vs(0.2±0.4)级,P<0.01],纽约心脏协会心功能分级显著改善[(3.4±0.8)级vs(1.4±0.5)级,P<0.01],血浆N末端B型利钠肽原水平显著下降[(1957.6±392.5)ng/ml vs(458.7±161.0)ng/ml,P<0.01]。无围手术期死亡。术后第12、24、36个月患者的生存率分别为100.0%、86.7%和86.7%。结论:改良扩大Morrow手术是治疗青少年HOCM安全、有效的手段,术中充分暴露是保证手术效果的重要措施。展开更多
目的:总结改良扩大Morrow术治疗肥厚型梗阻性心肌病的临床经验,分析其近中期结果。方法:回顾性分析2012年5月至2019年6月,在我院行改良扩大Morrow术的26例肥厚型梗阻性心肌病患者临床资料。其中女性18例,男性8例,年龄31~67岁,平均年龄(4...目的:总结改良扩大Morrow术治疗肥厚型梗阻性心肌病的临床经验,分析其近中期结果。方法:回顾性分析2012年5月至2019年6月,在我院行改良扩大Morrow术的26例肥厚型梗阻性心肌病患者临床资料。其中女性18例,男性8例,年龄31~67岁,平均年龄(45.6±13.5)岁。所有患者均经主动脉切口行改良扩大Morrow术,合并心脏病变同期处理,比较术前、术后及随访时超声心动图、心电图结果及并发症情况。结果:全组无手术死亡,单纯行改良扩大Morrow术18例,同期冠状动脉旁路移植术1例,二尖瓣成形或置换术5例,主动脉瓣置换术1例,心房颤动改良迷宫术1例。随访3~90个月,左心室流出道压差[(20.3±17.5)vs.(65.2±27.5)mm Hg,1 mm Hg=0.133 k Pa]、最大室间隔厚度[(18.6±6.4)vs.(26.3±5.1)mm]均较术前明显降低,LVEDD[(43.3±4.1)vs.(38.7±4.9)mm]较术前增加,差异均有统计学意义(P<0.05);24例(92.3%)患者NYHA心功能分级Ⅰ或Ⅱ级,较术前明显改善(P<0.01),二尖瓣反流程度减轻(P<0.01),二尖瓣收缩期前向运动现象消失。术后并发症包括:III°房室传导阻滞2例(8.3%);2例患者因切除范围不够致术后残余左心室流出道压差,1例再次行改良扩大Morrow术。结论:肥厚型梗阻性心肌病患者行改良扩大Morrow术可获得良好的近中期效果,不良事件发生率低,远期结果有待进一步随访观察。展开更多
