Single coronary artery (SCA) is a very rare coronary anomaly. The accurate diagnosis of the entity requires multimodality imaging of the coronary anatomy. SCA is often incidentally diagnosed when patients are investigated for symptoms of suspected coronary artery disease with invasive or non-invasive coronary angiography. There are no established diagnostic electrocardiographic or echocardiographic criteria to identify the presence of SCA, which makes the diagnosis a far-reaching fruit. We present a young male patient presenting with a non-ST elevation myocardial infarction. He was found to have SCA on invasive coronary angiography, which was subsequently confirmed by CT coronary angiography.
