Infants with one functional cardiac ventricle often undergo the Norwood procedure which seeks to create unobstructed outflow from the single ventricle to aorta using a complex aortic arch reconstruction. The distal region of the patch used to fashion the neo-aorta terminates near the aortic isthmus, and represents an area of extensive challenge and manipulation for cardiothoracic surgeons. Re-coarctation in this region is common after the Norwood procedure and may be linked with longer-term morbidity and mortality. Echocardiography (TTE) is the primary means of surveillance of the aortic isthmus, though measurements are often difficult due to poor acoustic windows and lack of patient cooperation. To date, there have been no studies that assess how accurately TTE measures the aortic isthmus relative to a computed tomography (CT) derived gold standard. Read More
