Abstract

Atrial septal abnormalities are common congenital lesions that remain asymptomatic in many patients until adulthood. Adults with atrial septal defects (ASD) most commonly have ostium secundum ASD. Transcatheter closure has become increasingly popular in recent years as a successful alternative method to surgery for treating ASD and patent foramen ovale (PFO). The overall rate of ASD transcatheter closure device embolization has been reported to be less than 1%; however, retrieving the device via surgery or by trans-catheter route can be necessary. The current manuscript describes a systematic review of the techniques used to retrieve ASD closure devices, as well as their success rates, complications, and limitations. A comprehensive search was performed covering various databases including PubMed, MEDLINE, SCOPUS, Google Scholar, and Cochrane Library from inception until April 2022 for English-published case reports, case series, and experimental studies investigating the indications, safety, and limitations of ASD closure and ASD device retrieval by transcatheter approaches. Finally, 20 studies were included in our review. Our findings showed that most of the studies used a single snare technique; of these, all but one reported 100% success. Double tool retrieval methods (snare plus snare, snare plus bioptome, or snare plus forceps) and the gooseneck snare technique yielded 100% success. One study that used the lasso technique reported unsuccessful retrieval and the need for surgical intervention. More recently, the novel coronary wire trap technique was introduced, which provides a simpler method for embolized device removal by trapping the device for retrieval using coronary wire. © 2024 HMP Global.
