Carotid-Subclavian Artery Index: New Echocardiographic Index to Detect Coarctation in Neonates and Infants

Recurrent Coarctation After Neonatal Univentricular and Biventricular Norwood-Type Arch Reconstruction

“…Aortic arch dimensions on the initial preoperative echocardiogram were measured at multiple locations, including the ascending and transverse aorta, aortic isthmus, and the distance between the takeoff of the left carotid and subclavian arteries, by a single cardiologist (HH) [19]. Peak and mean aortic arch gradients were measured from the discharge echocardiogram.…”

Predictors of Inadequate Mixing in Transposition of the Great Arteries — a Critical Neonatal Condition

“…For instance, the carotid-subclavian index, 22,25,26 the isthmus/ductus ratio 27 or a combination between ventricular disproportion, aortic and ductal isthmus measurements can help to better characterize aortic coarctation in newborns and fetuses. 28,29 In pulmonary atresia with intact ventricular septum, a critical CHD with ductal-dependent pulmonary circulation, the tricuspid valve z score, and the right to left ventricular ratios were described as predictors of outcome in fetuses and neonates as well.…”

“…[20][21][22][23][24] Furthermore, there are sev- eral studies that emphasize the role of echocardiography in decision-making in different critical CHDs in newborns.…”

Original Research. Diagnosis of the Aortic Coarctation in the Neonatal Period — a Critical Condition in the Emergency Room

“…8,9 The Z score was also calculated by correlating body surface area and aortic annulus diameter, mitral annulus, distal portion of the aortic arch, and aortic isthmus using the Detroit calculation formula. Newborn demographic data analyzed included: gender, mean age at the time of the first echocardiographic evaluation, mean weight, mean length, average body surface area, mean gestational age, and antenatal diagnosis.…”
