Comparative StudyContrast-enhanced magnetic resonance angiography of persistent fifth aortic arch in children.
Cine angiography and echocardiography have been utilized to diagnose congenital aortic arch anomalies. However, the visualization of great vessels by echocardiography is limited, while cine angiography requires cardiac catheterization with ionizing radiation. Contrast-enhanced magnetic resonance angiography (MRA) is a noninvasive modality suitable for visualization of congenital aortic arch anomalies. ⋯ Contrast-enhanced MRA is a safe, accurate, and fast imaging technique for the evaluation of persistent fifth aortic arch and may obviate the need for conventional cine angiography. Cardiac catheterization may be reserved for some types of complicated congenital heart disease and for obtaining hemodynamic information.

Case ReportsRight-sided superior vena cava draining into the left atrium: a rare anomaly of systemic venous return.
The most commonly encountered systemic thoracic venous anomaly is a persistent left superior vena cava that drains into the right atrium via the coronary sinus. A much rarer systemic venous anomaly is that of isolated anomalous drainage of a normally positioned right superior vena cava (RSVC) into the left atrium (LA). ⋯ We report the case of a toddler with asymptomatic hypoxemia resulting from anomalous drainage of a normal RSVC into his LA. This was diagnosed non-invasively by contrast-enhanced chest CT.
