Cardiac Catheterization III: Left Heart Catheterization

56
Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...

科学领域:

  • 心脏病学 心脏病学
  • 血管外科 血管外科
  • 神经学 神经学

背景情况:

  • 心房动 (AF) 是美国普遍存在的一种心律失常,经常导致源自左心房附属体 (LAA) 的栓塞性中风.
  • 该LAA表现出明显的解剖学和生理学特征,像花菜类型的变异与非膜AF中风风险增加有关.
  • 抗凝药是AF中风预防的标准,但出血并发症限制了许多患者的使用.

研究的目的:

  • 审查外科手术左心房附属体 (LAA) 封闭的疗效.
  • 要总结当前的非手术LAA关闭方法.
  • 探索LAA关闭战略的未来方向.

主要方法:

  • 关于手术LAA闭塞结果的主要研究的综述.
  • 皮穿式LAA关闭装置和技术的总结.
  • 讨论LAA解剖学及其与中风风险的关系.

主要成果:

  • 手术LAA封闭已经证明在预防栓塞事件方面是有效的.
  • 有各种可用于LAA关闭的皮装置,可以作为抗凝药的替代品.
  • LAA解剖学,特别是花菜类型,与较高的中风风险有关.

结论:

  • 关闭LAA提供了一种可行的替代方法,用于预防AF患者中风的抗凝药,这些患者不能容忍血液稀释剂.
  • 手术和皮肤穿刺LAA关闭方法都在进步,目前正在研究最佳技术和长期结果.
  • 了解LAA形态对于风险分层和定制中风预防策略至关重要.
