摘要
纵向支架缩短是一种已知的现象,然而,冠状动脉弯曲对纵向支架缩短的影响尚不清楚。本研究的目的是确定在现实情况下冠状动脉曲率对纵向支架缩短的影响。本研究共纳入86例连续行冠状动脉支架植入术的患者。冠状动脉弯曲度定义为冠状动脉弯曲长度除以直长。纵向支架预缩定义为植入后的支架长度除以植入前的支架长度。在弯曲的冠状动脉中,冠脉支架的平均纵向缩短率约为94%。纵向支架缩短率与冠状动脉弯曲度呈正相关(r = -0.86, P < 0.01)。冠状动脉弯曲与冠状动脉支架明显的纵向预缩有关,因此在确定弯曲冠状动脉支架长度时应考虑纵向预缩,弯曲冠状动脉通常需要更长的支架。
Impact of Coronary Artery Curvature on the Longitudinal Stent Foreshortening: Real-World Observations
Longitudinal stent foreshortening is a known phenomenon, however, the impact of coronary artery curvature on longitudinal stent foreshortening remains unclear. The aim of this study is to determine the impact of coronary artery curvature on the longitudinal stent foreshortening in the real-world scenarios. A total of 86 consecutive patients underwent coronary stent implantation were included in the present study. The degree of coronary artery curvature was defined as the length of the coronary artery curvature divided by the straight length. Longitudinal stent foreshortening was defined as the stent length after implantation divided by the stent length before implantation. The mean longitudinal foreshortening rate of coronary stents was about 94% in curved coronary arteries. Longitudinal stent foreshortening rate was positively correlated with the degree of coronary artery curvature (r = –0.86, P < 0.01). Coronary artery curvature is associated with significant longitudinal foreshortening of coronary stents, thus longitudinal foreshortening should be considered on deciding the stent length in curved coronary artery and a longer stent is usually needed in curved coronary artery.
期刊介绍:
The field of biomechanics concerns with motion, deformation, and forces in biological systems. With the explosive progress in molecular biology, genomic engineering, bioimaging, and nanotechnology, there will be an ever-increasing generation of knowledge and information concerning the mechanobiology of genes, proteins, cells, tissues, and organs. Such information will bring new diagnostic tools, new therapeutic approaches, and new knowledge on ourselves and our interactions with our environment. It becomes apparent that biomechanics focusing on molecules, cells as well as tissues and organs is an important aspect of modern biomedical sciences. The aims of this journal are to facilitate the studies of the mechanics of biomolecules (including proteins, genes, cytoskeletons, etc.), cells (and their interactions with extracellular matrix), tissues and organs, the development of relevant advanced mathematical methods, and the discovery of biological secrets. As science concerns only with relative truth, we seek ideas that are state-of-the-art, which may be controversial, but stimulate and promote new ideas, new techniques, and new applications.
