A 22-year-old female with a history of aortic and mitral valve replacement was admitted with a 4-week history of dyspnea and chest pain. Emergency coronary angiography revealed not only external compression of the left main coronary artery due to an aortic root abscess, but also the dual left anterior descending artery arising from the left and right coronary sinus. Although aortic root abscess is a well recognized complication of aortic valve endocarditis, coronary artery compression is an unusual mode of presentation. The binary distribution of the left anterior descending artery may limit the extent of ischemic insult to the anterior wall and thus led to a more insidious clinical course.
一名有主动脉瓣和二尖瓣置换病史的22岁女性因4周的呼吸困难和胸痛病史入院。急诊冠状动脉造影显示，不仅存在主动脉根部脓肿导致的左主干冠状动脉外部压迫，还发现左前降支动脉分别起源于左、右冠状动脉窦。虽然主动脉根部脓肿是主动脉瓣心内膜炎公认的并发症，但冠状动脉受压是一种不常见的表现形式。左前降支动脉的这种双源分布可能会限制前壁缺血损伤的范围，从而导致更隐匿的临床病程。
