Pitfalls in Echocardiography: Coarctation of the Aorta Presenting as XXXX ( @entity384 ).

@entity1 @entity712 @entity384 @entity1498 @entity6554
UNASSIGNED: Purpose: The morphologic spectrum of @entity1498 extends from discrete @entity6554 of the entire aortic arch. Neonates with @entity1498 frequently present with @entity712 and critically reduced perfusion of the descending aorta following ductal closure. During the recent years we observed several @entity1 with @entity1498 who presented beyond the neonatal period with @entity384 ( @entity384 ). We reviewed our @entity1 with @entity1498 to determine whether this presentation represents an exception or is relevant for the differential diagnosis of @entity1 with @entity384 . Materials and Methods: From 1/2001 to 12/2013 74 babies with @entity1498 were diagnosed in our institution. 50 @entity1 presented in the neonatal period and 24 @entity1 beyond the first month. Results: 5/74 @entity1 presented after the neonatal period with poorly contractile, dilated left ventricles. Echocardiographic detection of the @entity1498 was facilitated by application of the ductal view and by Doppler interrogation of the celiac artery revealing a significantly diminished systolic flow velocity. All @entity1 underwent resection of the @entity1498 and end-to-end anastomosis of  the aorta. Postoperative normalization of left ventricular function was observed within a median interval of 2 months. Conclusion: Coarctation of the aorta presenting as @entity384 accounted for 21% of our @entity1 with @entity1498 who presented beyond the neonatal period and 7% of those in the first year of life. The stenosis was difficult to detect because of its distal location and normal configuration of the aortic arch. @entity1498 should be included in the differential diagnosis of @entity1 with @entity384 and requires careful examination of the isthmic region in these @entity1 .
