摘要
左心室假腱索(LVFT)是左心室心腔内一种常见的解剖变异,为连接室间隔与乳头肌或左心室游离壁的一种条索状结构,其形态和分布多样。LVFT并非是不发挥作用的“旁观者”:在电学方面,LVFT的附着部位是室性心律失常的潜在异位激动点;在力学方面,LVFT的牵拉与心室重塑密切相关;此外,LVFT也可能对血流动力学产生不良影响。现对LVFT的研究现状进行阐述。
Left ventricular false tendon(LVFT)is a chord-like structure to connect ventricular septum with papillary muscle or left ventricular free wall,has diversiform morphology and distributing as a common anatomic variation.LVFT is not a non functioning bystander.In terms of electricity,the attachment site of LVFT is the potential ectopic beat of ventricular arrhythmia;in terms of mechanics,the traction of LVFT is closely related to ventricular remodeling;furthermore,adverse effects on hemodynamics may be caused by LVFT.This paper expounds the research status of LVFT.
