概括

门内透导管大动脉置换 (TAVR) 在所有年龄段提供血液动力学益处,但对老年人来说,3年死亡风险更高. 传单血栓的患病率有所不同,但年龄不是预测因素.

科学领域:

心脏病学心脏病学
干预心脏病学干预心脏病学
心脏外科手术心脏外科手术

背景情况:

门中门跨导管大动脉置换 (TAVR) 是生物假体门恶化的一种成熟治疗方法.
现在扩展的适应症包括具有结构膜恶化的年轻患者.
了解与年龄相关的结果对于优化不同患者群体的TAVR至关重要.

研究的目的:

为了评估不同年龄组的门内TAVR的临床结果.
评估与年龄相关的程序并发症和长期结果的差异.
为了确定年龄对死亡率,中风和门血液动力学后TAVR的影响.

主要方法:

对273名接受门内TAVR的患者进行了回顾性分析.
患者分为三个年龄组:<75,75-84岁和≥85岁.
随访包括心声学和计算机断层扫描用于血液动力学和并发症评估.

主要成果:

在所有年龄组中观察到低的住院并发症率.
在≥85岁的患者中,发现3年内全因死亡风险较高.
在所有年龄组中都观察到一致的3年血液动力学改善.
传单血栓在老年患者中更常见,但并没有根据年龄预测.

结论:

门内TAVR提供持续的血液动力学益处,但与老年人3年死亡率的增加有关.
传单血栓症的年龄相关差异需要进一步调查.
低衰减叶片加厚的影响需要进一步的研究.

Heart Valves

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...
