Congenital coronary artery (CA) anomalies can be classified into abnormalities pertaining to origin, course and termination, which can serve as important prognostic factors. Some of these anomalies are asymptomatic with a benign clinical course, while others can give rise to symptoms of chest pain and even sudden death (e.g. malignant interarterial CA course). Acquired CA abnormalities such as coronary arterial aneurysms associated with Kawasaki disease may result in thrombi development, necessitating a change in patient management. Early and accurate diagnosis of these abnormalities is therefore crucial but can be technically challenging owing to the small size of the coronary arteries, rapid heart rate, and limited cooperation of children. Whilst the proximal aspect of the coronary arteries can be visualized with echocardiography, computed tomography angiography (CTA) provides a more comprehensive assessment of the coronary arteries even without ECG-triggering. Moreover, CTA offers the flexibility of customizing acquisition parameters for the individual patient. As such, CTA is rapidly becoming the imaging modality of choice for evaluating complex congenital and acquired CA abnormalities in children.

The aims of this educational exhibit are to review the embryology of coronary arteries, outline congenital and acquired CA abnormalities, and discuss the utility of optimizing low-dose CTA to evaluate these abnormalities in children. Determining the origin and course of CAs is key for pre-operative planning in some types of congenital heart disease, for example, the arterial switch procedure for transposition of great arteries and in Taussig Bing anomaly. Identifying the malignant interarterial intramural CA course can be lifesaving. Evaluating for co-existing abnormalities, such as CPAM, is also an integral part of these studies. Read More

With increased use of CT and MR for coronary imaging in children, pediatric radiologists are more likely to encounter the unusual finding of dilated or aneurysmal coronary arteries. An understanding of the differential diagnoses and clinical associations is critical for accurate diagnosis and timely initiation of therapy. This educational exhibit begins with a discussion of diagnostic criteria and terminology for describing coronary dilation. The exhibit includes representative cases of the various causes of coronary artery dilation and aneurysms in children, including congenital abnormalities (coronary artery fistula, ALCAPA, ARCAPA), acute infection/inflammation (Kawasaki Disease, MIS-C), chronic immune-mediated disorders (Takayasu arteritis, polyarteritis nodosa), connective tissue diseases, and iatrogenic/acquired etiologies. Implications for surgical/interventional planning, particularly for congenital etiologies, are a key attribute of cross-sectional imaging. Imaging characteristics and clinical manifestations are discussed in the context of each case. Read More

Coronary artery anomalies span a broad spectrum of clinical outcomes from clinically insignificant to deadly. Although uncommon, these conditions can be devastating and reflect a significant proportion of premature deaths in young people, particularly young athletes. As imaging becomes more common in the pediatric and young adult population, as well as the increase of cardiac imaging in adults, many of these anomalies can be found incidentally. The purpose of this educational exhibit is to provide a framework for assessing coronary artery anomalies and to review several classic cases. The exhibit will discuss anomalies of origin, course, and termination, as well as hemodynamically significant and non-hemodynamically significant anomalies. Specific cases include interarterial course, prepulmonic course, retro aortic course, ALCAPA, ARCAPA, coronary artery fistula, and coronary artery aneurysms (Kawasaki, MIS-C). Examples of post-procedural findings will also be included. Given the variety of coronary artery anomalies and varied clinical presentations, it is important for radiologists to recognize and correctly diagnose these diseases to ensure appropriate management.
