Anatomy of the Heart

93.3K
The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.

科学领域:

  • 心脏病学 心脏病学
  • 病理学 病理学 病理学
  • 免疫学 免疫学 免疫学

背景情况:

  • 无法解释的心脏骤停通常被认为源于已知的潜在疾病.
  • 尸检可以揭示以前未被诊断的病理,导致心脏事件.

研究的目的:

  • 调查心肌多重微伤痕 (MMS) 与无法解释的心脏骤停之间的潜在联系.
  • 在心脏突然死亡和心律失常的患者中识别潜在的病理发现.

主要方法:

  • 介绍了三个临床病理学病例,涉及患者死于无法解释的心脏骤停.
  • 对临床记录的审查,以将心肌病理与死亡前节律失常相关联.
  • 检查尸检结果以确定心脏微伤痕的位置和程度.

主要成果:

  • 在所有三名患者的心肌中都发现了多个微小痕 (MMS).
  • 患有MMS的患者表现出心律失常,如心房动和非持续性心室低心率.
  • MMS位于左心室,心房和肺静脉和左心房的结合点.
  • 所有患者都接受了COVID-19的补充疫苗接种;一个人有COVID-19的病史.

结论:

  • 应考虑心脏MMS作为未解释的心脏骤停的潜在差异诊断,特别是当心律失常复杂时.
  • 存在MMS可能表明以前未被识别的病理过程导致心脏突然死亡.
