Cardiac Catheterization II: Right Heart Catheterization

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

Cardiac Catheterization III: Left Heart Catheterization

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...

  • 医疗器械技术 医疗器械技术

背景情况:

  • 有限的数据存在于手术程序和早期的结果,用于跨关节跨管三管替换 (TTVR).
  • 评估TTVR的疗效,特别是在更大的设备尺寸下,对于管理严重的三角吐来说至关重要.

研究的目的:

  • 评价第一个在人体内进行的跨状TTVR的程序和临床结果.
  • 专门评估接受大型设备尺寸的患者的结果,其中有效性已受到质疑.

主要方法:

  • 76名患者的回顾性注册,他们使用LuX-Valve Plus系统进行了TTVR,用于症状三管吐.
  • 数据是从2022年1月到2024年2月在15个国际中心收集的.
  • 终点包括手术TR降低,住院死亡率,不良事件和1个月存活率,按器件尺寸分层 (≥55毫米与<55毫米).

主要成果:

  • 在90.8%的患者中成功降低TR至≤1+,其中75%的接收器件≥55mm.
  • 一个月生存率为94.4%,NYHA功能类显著改善.
  • 住院死亡率低 (5.3%),严重出血 (6.6%) 和新的起器植入 (3.9%);没有观察到中风或肺栓塞.
  • 在接受小型 (<55毫米) 和大型 (≥55毫米) 设备的患者之间,结果是可比的.

结论:

  • 横TTVR在治疗严重三管吐时显示出安全性和有效性.
  • 该程序甚至在患有非常大的三形解剖学需要更大的设备的患者中也显示了可比的结果.
