*the article, "comparative effectiveness of surgical ligation and catheter closure of patent ductus arteriosus in preterm infants", was reviewed.The article presents a retrospective, single-center experience to evaluate the association, if any, between closure modality (surgical ligation sl vs.Catheter cc) of a hemodynamically significant patent ductus arteriosus (pda), after failure of or contraindication to medical therapy, and immediate procedural complications, and post-procedure physiologic status in preterm (gestational age < 32 weeks) infants.All catheter-based closures were performed with the amplatzer piccolo device.The article concluded that the risks of serious adverse outcomes were low, regardless of the modality.Transcatheter closure of pda was comparable to surgical ligation; both procedures were effective and had few major adverse effects.Further investigation into long-term outcomes associated with both procedures is warranted.[the primary and corresponding author is girija natarajan, division of neonatology, central michigan university, children¿s hospital of michigan, 3901 beaubien blvd, pediatrics detroit, central mi, usa with corresponding email: gnataraj@dmc.Org].

Patient outcome of death in the research article for patent ductus arteriosus closure with either surgical or closure with an amplatzer piccolo device was reported in a subject population with multiple co-morbidities.A more comprehensive assessment could not be performed as the event was non-contemporaneously reported through a literature review and no device or individual patient information was received for analysis.Based on the available information, the root cause of the reported event could not be conclusively determined.There is no indication of a product quality issue with regards to manufacture, design, or labeling.(b)(6) 2023: death date is estimated (b)(6) 2021, the same date the study ended.
