概括
预测的假肢-患者不匹配 (PPMp) 显示了在手术上更换大动脉 (SAVR) 后与测量PPM (PPMm) 的次优一致性. 在小门尺寸使用预测不匹配时建议谨慎使用,以防止意外的测量不匹配.
科学领域:
- 心脏病学 心脏病学
- 生物医学工程 生物医学工程
- 手术创新 在外科创新.
背景情况:
- 手术性大动脉置换 (SAVR) 后的假肢-患者不匹配 (PPM) 与不良的临床结果和减少门耐用性有关.
- 对PPM的准确评估对于优化SAVR后患者预后至关重要.
研究的目的:
- 在接受SAVR的患者中,回顾评估预测PPM (PPMp) 和测量PPM (PPMm) 之间的一致性.
- 在三种不同的生物假体类型中比较PPMp和PPMm:Magna Ease,Intuity和Inspiris Resilia.
主要方法:
- 对1323名SAVR患者的分析,对872人提供完整的血液动力学数据.
- PPMm通过心声波测量有效孔面积指数 (EOAi) 确定;PPMp使用基于患者和假肢特征的参考值进行评估.
- 与PPMm相比,PPMp的灵敏度,特异性,预测值和准确性的评估,按假肢类型,尺寸和直径分层.
主要成果:
- 总体上,PPMp和PPMm之间的一致性为72.8% (635/872名患者).
- 在Magna Ease,Intuity和Inspiris Resilia生物假体中没有观察到PPMp-PPMm一致性的显著差异.
- 预测和测量PPM之间的不一致性在较小的门尺寸中更为明显,PPMp的整体准确性为73%.
结论:
- 在SAVR后,预测和测量的假肢患者不匹配之间的一致性是不理想的.
- PPMp的预测准确性有限,特别是对于较小的门尺寸,需要仔细的临床考虑.
- 目前用于预测PPM的方法可能需要改进,以提高准确性并避免意外的测量不匹配,特别是在特定的患者和假肢配置中.
