ABSTRACT

Device-induced aortic obstruction is a known rare complication following transcatheter closure of patent ductus arteriosus in extremely low-birth-weight infants. Various mechanisms have been proposed. We report the first description of late aortic obstruction due to ductal vasoconstriction on pulmonic end causing device to be gradually pushed out of aortic end in a 980-gram premature infant.

Keywords: Doppler echocardiography; Patent ductus arteriosus; coarctation of the aorta; extremely low-birth-weight infants; premature infant.
