| Popis: | Introduction. Diagnosis of neonatal coarctation of the aorta (CoA) still presents a challenge in routine practice because of absence of reliable morphologic and functional parameters for early detection of this congenital heart defect in newborns. Objective. The aim of this study is to identify easy obtainable two-dimensional echocardiographic parameters for detection of the CoA in newborns. Methods. Echocardiographic evaluation was performed in 30 newborns with CoA and 20 healthy neonates (control group). Measurements of the proximal transverse arch (PTA), distal transverse arch (DTA), isthmus, distance between the left common carotid artery (LCCA) at the origin of the left subclavian artery (LSA), were obtained by two-dimensional echocardiography. Aortic arch hypoplasia was defined using Mouleart, Karl and Mee criteria, and Z-value. Index 1 was calculated as a ratio of DTA and distance between origins LCCA-LSA, Index 2 was calculated as a ratio of the ascending aorta and the distance between LCCA-LSA origins, and Index 3 was calculated as a ratio of PTA and distance between LCCA-LSA origins. Results. Index 1 was significantly lower in patients with CoA in comparison with control group (0.50 vs. 1.39; p≤0.01). A cutoff point at 0.39, for Index 1, showed a sensitivity of 92% and specificity of 99% for the diagnosis of neonatal CoA, while cut off points at 0.69 and 0.44, for Index 2 and Index 3, showed the highest sensitivity and specificity for the diagnosis of CoA in newborns. Conclusion. By using these echo indexes, two-dimensional echocardiographic aortic arch measurement becomes a simple, reliable noninvasive method for the evaluation of aortic coarctation in newborns and may lead to earlier diagnosis and subsequent surgical correction. |
