As reported in a research article, a patient had an amplatzer piccolo device implanted which later embolized.It was also indicated that another amplatzer plug was implanted in the patent ductus arteriosus and that the piccolo was eventually removed from the patient after an unsuccessful attempt.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 regards to manufacture, design, or labeling.

The article, ¿risk factors associated with device embolisation or malposition during transcatheter closure of patent ductus arteriosus¿, was reviewed.The article presented a case study of a 2 month old patient weighing 2.2 kg with down syndrome, high anorectal malformation (arm), near systemic pulmonary artery pressures and large pericardial effusion.It was reported that on an unknown date, a 5-2mm amplatzer piccolo occluder was chosen for implant to treat patent ductus arteriosus (pda) that was sized 4 mm.It was then reported on an unknown date, the device had embolized and initial attempts to retrieve the device had failed as the embolized device was deeply lodged into the smaller right lower lobe branch.A decision was made to implant an 8mm amplatzer vascular plug ii into the pda.After successful implant, it was reported the pericardial effusion was drained and the patient was conservatively observed for piccolo embolization.It was reported the piccolo was recovered uneventfully on an unknown date.The article concluded device embolisation complicates 4% of transcatheter duct closures, with need for surgery in one-fifth of them.Larger ducts with high pulmonary artery pressures in younger and smaller infants are more often associated with device embolisation.Tubular ducts are more prone for embolisation compared to usual conical ducts.Softer vascular plugs are often associated with embolisations.Intentional device under sizing to avoid vascular obstruction in small patients is a frequent risk factor for embolisation.Precise echocardiographic measurements, correct occluder choice, proper technique and additional care in patients with high pulmonary artery pressures are mandatory to minimise embolisations.[the primary and secondary author was kothandam sivakumar, madras medical mission, 4a dr jj nagar, mogappair, chennai 600089, india, with corresponding email drkumarsiva@hotmail.Com].
