左心耳封堵器相关性血栓的预测因素研究进展

Progresses in predicting factors of left atrial appendage occluder associated thrombosis

器械相关性血栓(DRT)已被认为是左心耳封堵(LAAO)的重要并发症,与术后卒中发生率增加有关,高龄、缺血性卒中或短暂性脑缺血发作病史、左心耳增大、左心室射血分数降低、非阵发性心房颤动等被认为导致LAAO术后DRT危险性增高,然而关于DRT的预测因素仍然众说纷纭,无统一认识。本文通过分析国内外相关文献,对目前DRT的预测因素作一回顾及评述。

Device related thrombosis(DRT)has been considered as an important complication of left atrial appendage occlusion(LAAO),and is related to the increased incidence of postoperative stroke.Older age,history of ischemic stroke or transient ischemic attack(TIA),maximum diameter of left atrial appendage,decreased left ventricular ejection fraction(LVEF),non paroxysmal atrial fibrillation are increased risk of DRT after LAAO.However,there are still different opinions on the predictive factors of DRT.This paper reviews the current researches about predictive factors of DRT.
