A 42-year-old female developed central chest pain radiating to the left shoulder. Twelve lead electrocardiogram demonstrated no ischaemia and the serum troponin was raised at 28 (normal <13 ng/L), which peaked to 140 and fell to 67. Dual antiplatelet therapy with aspirin and clopidogrel was commenced for a presumed acute coronary syndrome. Transthoracic echocardiography demonstrated preserved biventricular function and mild mitral regurgitation (Supplementary data online, Movies S1 and S2). Invasive coronary angiography demonstrated unobstructed coronary arteries and no coronary atheroma (Supplementary data online, Movies S3, S4 and S5). A cardiovascular magnetic resonance (CMR) scan was arranged to investigate aetiology of the clinical presentation.

用心血管磁共振鉴定肺动静脉畸形和栓塞性心肌梗死。

一名 42 岁女性出现放射至左肩的中央胸痛。12 导联心电图显示无缺血，血清肌钙蛋白升高至 28（正常 <13 ng/L），最高为 140 并降至 67。开始使用阿司匹林和氯吡格雷双重抗血小板治疗以治疗疑似急性冠状动脉综合征。经胸超声心动图显示保留双心室功能和轻度二尖瓣关闭不全（在线补充数据，电影 S1 和 S2）。侵入性冠状动脉造影显示冠状动脉通畅，没有冠状动脉粥样硬化（在线补充数据，电影 S3、S4 和 S5）。安排心血管磁共振 (CMR) 扫描来调查临床表现的病因。
