自扩展式 (SE) 和气球可扩展式 (BE) 跨导管心脏 (THV) 在门内跨导管大动脉置换 (ViV-TAVR) 中显示出相似的存活率. SE THV的梯度较低,假肢与患者不匹配较少,这表明设计差异需要进一步研究.
科学领域:
- 心脏病学 心脏病学
- 干预心脏病学 干预心脏病学
- 生物医学工程 生物医学工程
背景情况:
- 过导管大动脉置换 (TAVR) 是大动脉狭窄的关键治疗方法.
- 门内 (ViV) TAVR用于退化的外科动脉.
- 在ViV-TAVR中,仅有有限的数据可以比较自扩展 (SE) 和气球可扩展 (BE) 跨导管心脏门 (THV).
研究的目的:
- 为了比较ViV-TAVR中SE和BETHV的临床和心声学结果.
- 评估SE与BETHVs进行ViV-TAVR的患者的生存和假肢患者不匹配情况.
主要方法:
- 对2013-2023年机构数据的回顾性分析.
- 包括接受ViV-TAVR的315名患者.
- 倾向性得分匹配 (1:1) 来比较SE和BETHV组,使用卡普兰-梅尔生存分析.
主要成果:
- 在73%的患者身上植入了SE THV.
- 在30天和1年后,与BE THV相比,SE THV显示出较低的平均大动脉梯度.
- 严重的假肢患者不匹配更常见于BE THVs (16%与6.2%相比).
- 30天和1年死亡率在两组之间相似 (分别为2.7%和7.5%).
- 生存率和中风发病率在长达5年的时间里相似.
结论:
- 自扩展和气球可扩展的THV在ViV-TAVR中显示了可比的生存率.
- 在BE THV中较高的残留梯度可能与门设计有关.
- 需要进行长期评估,以评估潜在的结构退行差异.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
