The following  factors are critical determinants of the success of ASD device closure

  1. Location of the defect ( Only ostium secundum )
  2. Size of the defect (<35mm .Never forget  simple truth , larger the defect shorter would be the  rim )
  3. Shape  of the defect (Please note ,none are strictly circular but most devices are ! )
  4. Eccentricity of the defect (RA aspect of ASD need not match LA aspect)
  5. Length of the rim ( 5mm said to be adequate)
  6. Thickness of the rim ( Least respected parameter .Thin filament like rims are notorious  in sagging the device into RA)
  7. Pre and Per- operative TEE (As Vital as the procedure)
  8. Technical expertise . (This includes extreme patience  of the primary operator .Most sub optimal results and complications are related to this.
  9. Good team ( Not every  interventional  cardiologist should  attempt this !)
  10. Courage to abandon the procedure
  11. Device brand (Probably less important )
