Long-Term (5- to 20-Year) Outcomes After Transcatheter or Surgical Treatment of Hemodynamically Significant Isolated Secundum Atrial Septal Defect

The American Journal of Cardiology, 04/25/2012

Long–term outcomes after secundum atrial septal defect (ASD) closure using modern methods are excellent. No significant differences were found between transcatheter closure (TC) versus surgical closure (SC) with regard to survival, functional capacity, atrial arrhythmias, or embolic neurologic events. Arrhythmia and neurologic events remain long–term risks after ASD closure, especially if the patient had pre–existing arrhythmia.
