Constriction of juxta-ductal aorta and rapid progression of obstruction in a newborn.

Abstract

A 13-day-old baby girl presenting with features of congestive cardiac failure was found to have coarctation of the aorta (CoA) and patent ductus arteriosus (PDA) by echocardiography. Doppler spectral display revealed moderate CoA. Echocardiogram, 12 hours later, showed severe juxtaductal aortic coarctation with spontaneous closure of PDA. This case emphasises the need to keep a close watch on the progress of CoA in the neonatal period, even if the duct has narrowed to a small size thus demonstrating the role of constriction of juxtaductal aorta in pathogenesis of coaractation. Closure of even asmall PDA can cause acute progression CoA in the presence of posterior shelf.
