Background: Device closure of a patent ductus arteriosus (PDA) is rapidly evolving, with the Amplatzer Piccolo Occluder (Abbott) receiving US Food and Drug Administration approval and becoming the first device approved for PDA closure in patients ≥700 g. We report on the first known cases of complete left pulmonary artery (LPA) occlusion following Piccolo closure of a PDA in premature infants. Methods: Retrospective chart analysis of PDA closures. Results: We have performed over 50 cases of Piccolo device closure of the PDA in preterm neonates in the past 2 years, with these 2 cases representing our only complications (4%). This represents a total complication rate similar to or lower than most centers that have published data for this procedure. Conclusions: Although rare, severe LPA obstruction can be seen in premature infants following device closure of the PDA. The Piccolo device is designed to ideally remain entirely intraductal. Although our device selection appeared to provide a device short enough for the given ductal length, we recommend, whenever possible, giving consideration to using the shortest possible device. We also recommend increasing the frequency of echocardiographic surveillance to weekly studies if at any time the imaging demonstrates an increase in the degree of obstruction/turbulence.
