Abstract:
This case describes an infantile presentation of left main coronary artery atresia (LMCAA), which involves complete absence of the left coronary ostium and left main coronary artery. The echocardiographic features of LMCAA that assist in making this diagnosis are detailed. Important imaging features that distinguish LMCAA from anomalous left coronary artery from the pulmonary artery are highlighted.
