The article, "spontaneous closure of patent ductus arteriosus in preterm babies after failed attempts at transcatheter device closure", was reviewed.This research article reported a case study on a 4 week old patient at 30 weeks gestation.Weight at the time of cardiac catheterization was 1.86 kg.The patient was transferred from an outside hospital for transcatheter device closure of the patent ductus arteriosus (pda) after failure of ibuprofen therapy.Echocardiography demonstrated a large pda (diameter 3 mm) with a left-to-right shunting, moderate left heart enlargement, and mild mitral regurgitation.An angiogram demonstrated a type c tubular pda with a minimum diameter of 3.5 mm.First, an 5-4 amplatzer piccolo occluder device (5¿4 size) was deployed.As the device was too long and encroached on the aorta and lpa, the device was removed before release.A second amplatzer piccolo occluder (5-2) device was attempted.On release, the device embolized to the right pulmonary artery.The device was successfully retrieved using a 10-mm goose-neck snare.The next morning, an echocardiogram showed that the pda was significantly smaller.On repeat echocardiogram 3 days later, pda had closed.Pda remained closed in follow-up echocardiogram after 10 weeks.[the primary and corresponding author of the article is ahmed deniwar, md, division of pediatric cardiology, mcgovern medical school, university of texas health science center, houston, texas, usa, with corresponding email: deniwar.Ahmed@gmail.Com.] related events : cn-140987, cn-140984.

As reported in a research article, a 5-4 amplatzer piccolo occluder device was deployed in a 4 week old patient at 30 weeks gestation.The device was too long and encroached on the aorta and lpa, and thus was removed before release.A second amplatzer piccolo occluder (5-2) device was attempted.On release, the device embolized to the right pulmonary artery.The device was successfully retrieved using a 10-mm goose-neck snare.A more comprehensive assessment could not be performed as the event was non-contemporaneously reported through a literature review and no device was received for analysis.Based on the information received, the cause of the reported incident could not be conclusively determined.There is no indication of a product quality issue with respect to labeling design or manufacturing of the device.
