Outcomes of transcatheter closure of patent ductus arteriosus with the off-label use of large occluders (≥16 mm)

摘要

Transcatheter closure is the first-choice strategy for the management of appropriate patients with patent ductus arteriosus (PDA). The management of large PDAs is challenging due to the limited available sizes of approved devices and the inherent risks of surgical ligation, especially in adults with calcified PDAs. This study aimed to assess the outcomes of the off-label use of large occluders at a tertiary center.
