title: Juxtaductal aortic atresia masquerading as coarctation.
abstract: Two cases of juxtaductal aortic atresia diagnosed as coarctation on clinical and Doppler echocardiographic grounds are presented. The misleading nature of the Doppler flow velocity characteristics in this condition is discussed and raises questions as to the source of these flow velocities in coarctation.
