A 54-year-old man with recurrent, persistent atrial fibrillation was found dead unexpectedly. He was reportedly non-compliant with his medications and was not on anti-coagulant therapy. He was found dead in his residence after complaining of abdominal discomfort a day prior to death. Postmortem examination revealed a thromboembolus occluding the left anterior descending coronary artery that originated from a mural thrombus in the left appendage, in addition to kidney infarcts. Although atrial fibrillation-related thromboembolism is often speculated to be a cause of myocardial infarction with non-obstructive coronary arteries, supporting pathological evidence is rare. This case documents radiological, macroscopic and microscopic images of this important complication from atrial fibrillation.

一名患有反复持续性房颤的 54 岁男性被发现意外死亡。据报道，他不遵守药物治疗，也没有接受抗凝治疗。他在死亡前一天抱怨腹部不适后被发现死在他的住所中。尸检显示血栓栓塞阻塞了左冠状动脉前降支，其起源于左附件的壁血栓，以及肾梗塞。尽管心房颤动相关的血栓栓塞常被推测是非阻塞性冠状动脉心肌梗死的原因，但支持病理学证据很少。本案例记录了房颤这一重要并发症的放射学、宏观和微观图像。
