A 19-year-old woman presented to the emergency department with arrhythmia and signs of cardiogenic shock. After a 12-lead electrocardiogram ruled out acute myocardial infarction, and cardiac magnetic resonance showed no sign of cardiomyopathy, cardiac computed tomography angiography (CCTA) was performed, displaying ostial atresia of the right coronary artery. She was thus referred to a specialist centre for congenital cardiovascular disease, where an electrophysiological study observed an arrhythmogenic focus on the posteromedial papillary muscle, which was ablated, and she has been asymptomatic since. When dealing with patients presenting with arrhythmias or cardiogenic shock, and no signs of myocardial infarction or cardiomyopathy, performing CCTA to study the anatomy of the coronary arteries is vital.
一名19岁女性因心律失常和心源性休克症状就诊于急诊科。在12导联心电图排除急性心肌梗死后,心脏磁共振成像未显示心肌病迹象,遂进行心脏计算机断层血管造影(CCTA),结果显示右冠状动脉开口处闭锁。于是她被转诊至先天性心血管疾病专科中心,在那里进行的电生理研究发现后内侧乳头肌存在致心律失常灶,该病灶被消融,此后她一直无症状。在处理出现心律失常或心源性休克且无心肌梗死或心肌病迹象的患者时,进行CCTA以研究冠状动脉解剖结构至关重要。
