Inclusion criteria

Inclusion criteria: Patients with atrial septal defect is confirmed by imaging tests such as echocardiography, cardiac CT, or cardiac MRI, and is hemodynamically stable (NYHA I-III) among patients undergoing atrial septal defect closure at our hospital. Patients were selected.

Exclusion criteria

Exclusion criteria: 1. Poor control patients with hypertension (160/90 mmHg) or hypotension (90/50 mmHg) 2. Those with a history of acute other organ diseases such as pulmonary embolus within 3 months 3. NYHA Patients with congestive heart failure with cardiac function IV degree 4. Patients with severe hepatorenal failure 5. Pregnant woman 6. Patients with or have a history of deep vein thrombosis 7. Patients with trauma or skin diseases in the leg-positive pressure area of the lower leg

Design outcomes

Primary

MeasureTime frame
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

MeasureTime frame
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.
