概括

自扩展式透导管大动脉置换后,亚临床血栓形成是常见的,影响18-24%的患者. 双动脉是这种早期植入后并发症的关键预测因素.

科学领域:

心脏病学心脏病学
放射学放射学是指放射学
生物医学工程生物医学工程

背景情况:

亚临床血栓形成是假肢结构性疾病的早期指标.
现有的研究主要集中在气球可扩展门上,在了解可自扩展假体血栓形成方面留下了一个空白.
过导管大动脉置换 (TAVR) 是一个不断发展的领域,随着假肢技术的发展.

研究的目的:

调查自扩展TAVR后的膜和周膜血栓的发生率,位置和预测因素.
分析假肢主体相互作用的多探测器计算机断层扫描 (MDCT) 预测因素.
评估血栓形成对假肢性能和临床结果的影响.

主要方法:

对100名接受Evolut R TAVR治疗的患者进行了回顾性分析,其功能正常.
在6个月的随访中使用了MDCT和胸前两维心声谱.
与临床结果和假肢血液动力学相关联的MDCT发现.

主要成果:

传单血栓发生在18%的患者中,严重病例发生在6%的患者中.
在24%和23%的患者中,分别观察到解剖性鼻和亚膜血栓形成.
双动脉是低衰减病变 (血栓形成) 的最强预测因素.

结论:

膜和周膜血栓瘤在自扩张TAVR后的早期并不罕见.
双主动脉与植入后血栓形成有显著的关联.
早期的血栓形成并没有影响这个队列中的假体血液动力学或临床结果.

关键词:

低衰减性病变的病变多探测器计算机断层扫描.亚临床小册子血栓形成症通过导管更换大动脉门.

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
