Why the study?
Does a size-based device selection strategy (coil for ≤1mm, ADO for >1mm) improve complete occlusion rates compared to coils alone in patients undergoing transcatheter PDA closure?
Does a size-based device selection strategy (coil for ≤1mm, ADO for >1mm) improve complete occlusion rates compared to coils alone in patients undergoing transcatheter PDA closure?
A size-based strategy using an Amplatzer Duct Occluder for larger PDAs and coils for smaller PDAs achieves superior complete occlusion rates compared to using coils alone.
No takes yet. Share an insight, caveat, or question.
Size-based PDA device selection may enhance occlusion; hypothesis-generating and should not yet change practice.
Gudausky et al. (2008) studied this question.
