Residual Patent Ductus Arteriosus After Surgical and Transcatheter Closure: Anatomical Challenges and Transcatheter Re-Intervention Strategies.

Key Points

• The aim is to assess the feasibility of transcatheter re-intervention for residual patent ductus arteriosus (PDA) despite previous device misplacement.
• Conducted a single-center case series
• Performed transcatheter re-intervention procedures
• Evaluated anatomical challenges prior to intervention
• Successfully closed residual shunts in all cases
• Demonstrated that anatomical evaluation improves procedural outcomes
• Showed feasibility even with malpositioned prior devices
