Coronary embolism due to prosthetic valve thrombosis is a rare cause of acute coronary syndrome. We report the challenging case of a 66-year-old female patient with non-ST-elevation myocardial infarction caused by left main coronary artery bifurcation embolism in the setting of mechanical aortic valve thrombosis. The patient was treated with intravenous thrombolysis. Four hours later, she suffered an anterior ST-elevation myocardial infarction due to left anterior descending artery embolization. Repeat coronary angiogram showed complete disappearance of the LMCA embolus with only distal LAD occlusion. The patient was further treated medically with excellent outcome.
心脏机械瓣膜血栓导致的冠状动脉栓塞是急性冠状动脉综合征的一个罕见病因。我们报告了一例 66 岁女性非 ST 段抬高型心肌梗死病例,其病因是左主干冠状动脉分叉处栓塞,同时合并机械主动脉瓣血栓。该患者接受了静脉溶栓治疗。4 小时后,她因左前降支动脉栓塞发生前壁 ST 段抬高型心肌梗死。再次冠状动脉造影显示左主干动脉栓塞完全消失,仅遗留左前降支远段闭塞。该患者接受了进一步的药物治疗,取得了良好的预后。
