A 74-year-old woman with paroxysmal atrial fibrillation underwent left atrial appendage (LAA) exclusion with a LARIAT snare device. Transesophageal echocardiogram one month later demonstrated a left atrial thrombus at orifice of the completely occluded LAA that subsequently resolved with two months of anticoagulation. This case highlights that LAA ligation with LARIAT device continues to pose a risk for left atrial thrombosis in the immediate post-operative period. It also emphasizes the need for further evidence regarding antiplatelet and anticoagulation therapy in these patients. © 2014 Wiley Periodicals, Inc.
一名74岁阵发性心房颤动女性患者接受了使用LARIAT圈套装置的左心耳（LAA）封堵术。术后1个月经食管超声心动图显示，完全闭塞的LAA开口处有左心房血栓形成，随后经过2个月的抗凝治疗血栓溶解。该病例表明，使用LARIAT装置进行LAA结扎在术后即刻仍有发生左心房血栓形成的风险。这也强调了需要进一步获取关于这些患者抗血小板和抗凝治疗的证据。© 2014威利期刊公司
