The article, "transcatheter closure of patent ductus arteriosus in preterm infants: results from a single-center cohort", was reviewed.The article presented a case study of a 30-day-old,1265g infant with a patent ductus arteriosus (pda).It was reported that on an unknown date, an unknown amplatzer piccolo occluder was chosen for implant with a 4f amplatzer torqvue delivery sheath.During procedure, the device was positioned in the ductus arteriosus but did not sufficiently occlude the defect.During the final attempt to deploy, it was reported the guidewire and the delivery sheath swapped their trajectory and got stuck into the right ventricle infundibulum.This led to a cardiac tamponade that was limited as long as the sheath stayed in the infundibulum.A decision was made to perform an emergency sternotomy to drain the pericardial effusion and ligate the pda.Post-procedure, the patient developed inferior vena cava (ivc) thrombosis that was treated with heparin therapy.It was noted the only symptom was an isolated macroscopic hematuria.The study concluded that transcatheter closure of a pda is a valid alternative to surgical ligation due to its high success rate and low incidence of post-ligature syndrome.Nevertheless, we also report rare, although serious complications.[(b)(6)].

As reported in a research article, transcatheter closure of patent ductus arteriosus in preterm infants: results from a single-center cohort.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.
