Congenital coronary anomalies are among the rare disorders of the otherwise normal heart. A 2-year-old toddler was evaluated for heart failure after a flu-like event 2 months before being suspicious of post-Covid-19 dilated cardiomyopathy. The cardiac magnetic resonance (CMR) technique displayed the basal to mid subendocardial to transmural scar, suggestive of an ischemic etiology. Further assessment with CT and invasive angiography confirmed the very uncommon left main coronary artery atresia (LMCAA) as the main cause of the patient's heart failure. This is not only the first reported LMCAA case that had undergone a CMR study but was also initially suspected with characteristic CMR findings.
先天性冠状动脉异常是正常心脏中罕见的疾病之一。一名2岁幼儿在疑似感染新冠病毒后扩张型心肌病的两个月前出现类似流感的症状，随后因心力衰竭接受评估。心脏磁共振成像（CMR）技术显示从心内膜下基底到中层至透壁的瘢痕，提示缺血性病因。通过CT和有创血管造影进一步评估，证实非常罕见的左冠状动脉主干闭锁（LMCAA）是该患者心力衰竭的主要原因。这不仅是首例报道的接受CMR研究的LMCAA病例，而且最初还通过CMR特征性表现得以怀疑。
