Mitral Valve Prolapse I: Introduction

4
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

科学领域:

  • 心脏病学 心脏病学
  • 医疗器械 医疗器械
  • 生物医学工程 生物医学工程

背景情况:

  • 两个单无心脏起器 (LPs),Micra VR和AVEIR VR,已在美国获得批准.
  • 脱位和/或栓塞 (D/E) 是LP的潜在并发症.
  • 不同的固定机制 (Micra的尼醇锡,AVEIR的活性螺旋螺旋) 可能会影响D/E速率.

研究的目的:

  • 为了评估AVEIR VR LP在美国FDA批准后的D/E发病率.
  • 为了比较AVEIR VR和Micra VR无心脏起器的D/E速率.

主要方法:

  • 在FDA MAUDE数据库中搜索了美国D/E关于AVEIR VR (2023年12月批准) 和Micra VR (2024年4月批准) 的报告.
  • 间接获得的报告被排除在外.
  • 美国的植入物总数来源于制造商报告.

主要成果:

  • 在21个月内,5990个AVEIR VR植入器的D/E率为0.88% (53/5990),其中60.4%发生在植入过程中.
  • 在8年的时间里,72,237个Micra VR植入器的D/E率为0.29% (211/72237).
  • 对于AVEIR VR的D/E比率明显高于Micra VR (0.88%与0.29%相比;p < .0001).

结论:

  • AVEIR VR植入物具有明显的脱和/或栓塞的风险,估计发生率为0.9%.
  • 与Micra VR.相比,这种发生率明显高.
  • 固定问题和设备与输送导管的分离与AVEIR VR D/E事件有关.
