Basic objectives -Others

To clarify the hemodynamic characteristics of atrial septal defect by examining how the response to leg-positive pressure stress changes 6 months after atrial septal defect closure in patients with atrial septal defect.

Assessment

Primary outcomes

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.

Key secondary outcomes

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.

Key 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.

Key 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
