What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Success rate of effective occlusion	Effective occlusion was defined as: 180 days after the surgery, Transthoracic echocardiography (TTE) showed that the position and shape of the occluder were normal, and no horizontal atrial shunt was observed. Re-examination by Contrast transthoracic echocardiography (cTTE) showed no or only a small amount of right-to-left shunt, that is, no microvesicles or less than 10 microvesicles/frame in left heart cavity after Valsalva and resting state.	180 days after surgery

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Recurrence or incidence of cryptogenic stroke during follow-up	Cryptogenic stroke was defined as a new focal cerebral ischemia confirmed by neuroimaging (cranial MRI or CT), which was performed After extensive vascular, cardiac, and blood evaluation, non-atherosclerotic, cardiogenic, or arteriolar obliterators were identified Cerebral infarction caused by the diagnosis of exclusion.	360 days, 2 years, 3 years, 4 years, 5 years after surgery
All-cause mortality rate	All-cause death is defined as death from any cause during the follow-up period.	360 days, 2 years, 3 years, 4 years, 5 years after surgery
Success rate of occluder implantation technology	The success of occluder implantation technology is defined as successful intraoperative implantation of occluder and immediate Echocardiography confirmed that the shape and position of the sealing device were appropriate, no new pericardial effusion or valve regurgitation was found, and the perioperative patients survived.	7 days after surgery
Success rate of surgical implantation of occlusion	Successful occluder implantation was defined as successful implantation of occluder and routine postoperative hospitalization that there were no serious adverse events related to surgery.	7 days after surgery
Success rate of complete occlusion	Complete occlusion was defined as the Transthoracic echocardiography (TTE) showing occlusion 180 days after surgery The position and shape of the apparatus were normal, and no horizontal atrial shunt was observed. The results of Contrast transthoracic echocardiography (cTTE) were reviewed there was no right-to-left shunt, that is, no microbubbles in the left heart cavity after Valsalva and resting state.	180 days after surgery
Success rate of effective occlusion	Success rate of effective occlusion was defined as: Transthoracic echocardiography (TTE) showed the position and shape of the occluder 360 days after the operation Normal condition, no horizontal atrial shunt; Reexamination by Contrast transthoracic echocardiography (cTTE) showed no or few results in other words, there were no microbubbles or less than 10 microbubbles in the left heart cavity after Valsalva and resting state.	360 days after surgery
Incidence of new atrial fibrillation and atrial flutter during follow-up period	atrial fibrillation and atrial flutter	360 days, 2 years, 3 years, 4 years, 5 years after surgery
Incidence of device-related serious adverse events during follow-up (including device-related thrombosis, embolic stroke, and peripheral stroke)	Arterial embolism, Atrioventricular block III degree, heart abrasion, infective endocarditis, severe hemolytic anemia, etc.);	360 days, 2 years, 3 years, 4 years, 5 years after surgery
Incidence of device defects.	Device defects refer to unreasonable risks that may endanger human health and safety under normal use of medical devices in clinical trials, such as label errors, quality problems and failures.	360 days, 2 years, 3 years, 4 years, 5 years after surgery
