概括

在复杂的分支支支架支架过程中,无意的支架变形 (USD) 在9.3%的病例中发生,通常是由于非光线重新布线或引导导管碰撞. 未经治疗的USD显著增加了主要的不良心脏事件,突出显示了检测和纠正的需要.

科学领域:

心血管医学心血管医学
干预心脏病学干预心脏病学
医疗成像医学成像

背景情况:

在冠状动脉支架期间,无意的支架变形 (USD) 可能会导致严重的并发症,包括失去接入和支架血栓形成.
美国美元在复杂的双叉支架支架中的发生率,机制和结果尚未得到充分理解.

研究的目的:

在OCTOBER试验中,使用光学连贯断层扫描 (OCT) 确定美元的发生率和机制.
评估医生检测和纠正意外非光线转接线的速度和USD.

主要方法:

对OCT扫描进行分析,以确定意外的光线下重新布线和USD.
通过审查程序性OCT扫描和血管图来确定USD机制.

主要成果:

在9.3%的OCT指导病例中,USD被确定为主要原因,其中非光线重新布线 (44%) 和导管导管碰撞 (40%) 是主要原因.
美元发生在18.5%的左主分支干预中.
未经治疗的USD与2年主要不良心脏事件发生率为23.3%,而经过纠正/可能纠正的USD则为0%.

结论:

美元与不良的程序结果和随访心脏事件有关,如果未被识别和纠正.
未被检测到的非光线重新布线和引导导管碰撞是USD的主要驱动因素.
左主分叉支架支架对USD具有更高的风险.

Plastic Deformations

Plastic Deformations

Plastic deformation represents a fundamental concept in materials science, which explains the irreversible change in the shape of a material when it experiences stress beyond its elastic capability. This phenomenon is important in structural engineering, especially in designing and analyzing cantilever beams—structures that are securely fixed at one end and bear loads at the opposite end. When these beams are subjected to loads within their elastic range, they will return to their...
