Anomalous Aortic Origin of Coronary Artery (AAOCA) is the 2nd most common cause of sudden cardiac death in the young. Coronary artery origins are evaluated as part of transthoracic echocardiography (TTE) and diagnostic precision may be limited by technical limitations, operator dependence, and patient cooperation. MRI and gated Cardiac Computed Tomographic Angiography (CCTA) are often utilized in patients where an anomaly is suspected on TTE. There is limited literature comparing TTE and CCTA in children with suspected AAOCA. The purpose of this study is to determine the distribution of various coronary anomalies comparing TTE and CCTA data, and define the added value advanced imaging brings in clinical decision-making.

Norwood procedure is a 3-stage surgical palliation for patients with functionally single ventricle anatomy, most commonly hypoplastic left heart syndrome. Complications after stage I operation are not uncommon and include Blalock Taussig Thomas (BTT) /Sano shunt abnormalities, Damus-Kaye-Stansel (DKS) anastomotic narrowing, and neo-aortic arch /branch vessel stenosis. Transthoracic echocardiography (TTE) is traditionally the mainstay for evaluation. The purpose of our study is to compare Gated Cardiac Computed Tomographic Angiography (CCTA) with TTE when evaluating post-operative complications after stage I Norwood procedure and implications of CCTA findings on management.

Infants with one functional cardiac ventricle undergo operations that yield unobstructed systemic outflow and a controlled source of pulmonary blood flow, often starting with the Norwood operation with Blalock-Taussig (BT) shunt. Infants with shunt dependent pulmonary blood flow are at risk for developing proximal pulmonary artery (PA) stenoses, which may result in morbidity and mortality. Echocardiography (TTE) is the primary means of surveillance for PA narrowing, but is limited by acoustic windows, operator experience and patient cooperation. Computed tomography (CT) offers high spatial resolution, rapid acquisition and relatively low radiation exposure. To date, there have been no studies comparing TTE and CT-derived measurements of the proximal PA anatomy in this high-risk population. Read More
