概括
在使用左心室辅助器件 (LVAD) 的患者中,假体门并发症并不常见. 然而,大动脉生物假肢功能障碍可能发生在LVAD植入后的一年内.
科学领域:

- 心血管外科心血管外科
- 生物医学工程 生物医学工程
背景情况:
- 左心室辅助器件 (LVAD) 对于末期心力衰竭管理至关重要.
- 假体门和LVAD之间的相互作用需要进一步调查患者的治疗结果.
研究的目的:
- 评估LVAD接受者与假肢相关的发病率和死亡率的发生率和特征.
- 评估 LVAD 患者假体门的长期性能.
主要方法:
- 在2004年4月至2022年12月期间接受HeartMate II或3 LVAD的726名患者的回顾性评估.
- 包括患有任何假的患者,分析置换时间 (LVAD前,后或后).
- 评估门位置 (大动脉,额头,三) 和类型 (机械与生物假体).
主要成果:
- 74名患者 (10.2%) 在LVAD插入周围进行了门置换.

The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar 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...

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...
