- Primary Outcome Measures
Name Time Method The primary outcome is the difference in stroke volume between resting and stressed leg-positive pressure before closure (up to 3 days) between normal controls and patients with atrial septal defect.
- Secondary Outcome Measures
Name Time Method Secondary outcomes: (1) Difference in stroke volume between rest and load before (within 3 days) and 6 months after atrial septal defect closure (2) Normal control and patients with atrial septal defect the difference between the stroke volume at rest and at load 6 months after atrial septal defect closure.
