Cardiac stress MRI evaluation of anomalous aortic origin of a coronary artery.

Myocardial ischemia is an insult that is primarily thought of in an adult population. However, there are several congenital and acquired cardiac lesions that may lead to myocardial ischemia in a pediatric population. One of the prominent congenital lesions is anomalous aortic origin of a coronary artery (AAOCA). Anomalous aortic origin of a coronary artery is one of the leading causes sudden cardiac death in pediatric and young adult patients, and thus the assessment of myocardial perfusion is of the utmost importance. Over the past decade, pharmacologic stress MRI has proven to be a highly sensitive and accurate diagnostic examination for qualifying myocardial perfusion in adults with coronary artery disease. This noninvasive imaging modality may be a useful tool in assessing the function impact of AAOCA on myocardial perfusion.
