科学领域:

  • 心血管外科心血管外科
  • 生物材料科学 生物材料科学
  • 临床心声扫描 临床心声扫描 临床心声扫描

背景情况:

  • 大动脉全移植 (AAV) 与假体相比,具有优势,但耐用性低于最佳.
  • 了解AAV功能障碍对于改善长期结果至关重要.

研究的目的:

  • 描述一下大动脉全移植门功能障碍的特征.
  • 确定影响AAV功能障碍发展的因素.

主要方法:

  • 570名患有冷保存的AAV.患者的心声学随访.
  • 基于外科手术技术的功能障碍分析 (根部置换,冠心下,包容气).
  • 调查与AAV功能障碍相关的患者和供体因素.

主要成果:

  • 随着时间的推移,在显著比例的患者中观察到大动脉全移植功能障碍 (吐或狭窄).
  • 根置换技术显示,与冠状动脉下 (23.0%) 和包容筒 (14.7%) 技术相比,显著的AAV反的发生率较低 (5.0%).
  • 较小的宿主大动脉环大小,较年轻的患者年龄 (冠状动脉下),以及较老的供体年龄 (根部置换) 与增加的AAV功能障碍有关.

结论:

  • 根置换技术与较少频繁的大动脉全移植变性有关.
  • 结果表明,改进外科手术程序,患者和捐赠者的选择标准,以提高AAV的寿命.
  • 改进的选择可能会导致主动脉全移植门的长期表现更好.
