纳入标准:

Inclusion criteria

排除标准:

1.由研究者判断,可以找到非PFO相关原因的缺血性脑卒中或TIA; 2.术前4周内发生大面积脑梗死; 3.经研究者根据患者的CTA或血管超声判断为颈动脉或椎动脉血管粥样硬化性狭窄(>50%或中度及以上); 4.超声心动图提示存在心内血栓或赘生物; 5.左室射血分数(LVEF)<35%; 6.心房颤动或心房扑动; 7.左心室室壁瘤形成或者左室室壁运动障碍; 8.合并重度的瓣膜狭窄或反流或既往接受瓣膜置换或修复手术; 9.合并肺动脉高压或PFO为特殊通道(左右心衰); 10.其他原因导致的右向左分流患者,包括房间隔缺损或肺动静脉瘘; 11.多孔PFO或PFO合并房间隔缺损(ASD); 12.植入部位或植入路径存在血栓、肿块或者赘生物; 13.术前3个月内急性心肌梗死或者不稳定心绞痛; 14.既往植入下腔静脉滤器、PFO闭合装置、ASD闭合装置; 15.研究者判断不适宜植入卵圆孔未闭封堵器的情形; 16.合并其他需要心脏外科手术的心脏畸形; 17.无法控制的全身或局部感染,败血症; 18.活动性感染需同期接受抗生素治疗(如为暂时性疾病,需在患者停止应用抗生素至少14天才能入组); 19.对抗血小板或抗凝治疗禁忌症者,如3个月内有严重出血情况;明确的视网膜病变、有颅内出血病史、明确的颅内疾病; 20.对钽、镍过敏患者; 21.处于妊娠期、哺乳期女性; 22.预期寿命少于1年的恶性肿瘤或其他疾病; 23.患者目前正在参与一项尚未完成主要终点的试验性药物或医疗器械临床研究。

Exclusion criteria:

1. As judged by the researcher, ischemic stroke or TIA with identifiable non-PFO-related causes; 2. Large-area cerebral infarction occurring within 4 weeks before surgery; 3. Carotid or vertebral artery atherosclerotic stenosis (>50% or moderate and above), as determined by the researcher based on the patient's CTA or vascular ultrasound; 4. Echocardiography suggesting the presence of intracardiac thrombus or mass; 5. Left ventricular ejection fraction (LVEF) <35%; 6. Atrial fibrillation or atrial flutter; 7. Left ventricular aneurysm formation or left ventricular wall motion abnormalities; 8. Severe valvular stenosis or regurgitation, or a history of valve replacement or repair surgery; 9. Pulmonary hypertension or PFO with special pathway (right-to-left heart failure); 10. Right-to-left shunt caused by other reasons, including atrial septal defect or pulmonary arteriovenous fistula; 11. Multi-patent PFO or PFO combined with atrial septal defect (ASD); 12. Thrombus, mass, or vegetation at the implant site or along the implantation path; 13. Acute myocardial infarction or unstable angina within 3 months before surgery; 14. Previous implantation of inferior vena cava filter, PFO closure device, or ASD closure device; 15. Situations deemed unsuitable for PFO closure by the researcher; 16. Other cardiac malformations requiring cardiac surgery; 17. Uncontrolled systemic or local infection, sepsis; 18. Active infection requiring concurrent antibiotic treatment (if a temporary condition, the patient must have stopped antibiotics for at least 14 days before enrollment); 19. Contraindications to antiplatelet or anticoagulant therapy, such as severe bleeding within the past 3 months; documented retinal disease, history of intracranial hemorrhage, or known intracranial disease; 20. Allergy to tantalum or nickel; 21. Pregnant or breastfeeding women; 22. Malignant tumors or other diseases with an expected life expectancy of less than 1 year; 23. Patients currently participating in an experimental drug or medical device clinical study whose primary endpoints have not yet been completed.
