简要总结
To evaluate the performance of patent foramen ovale (PFO) device developed by Lifetech Technology (Shenzhen) Co., LTD
详细描述
The purpose of this prospective, multi-center, single-group target value premarket clinical trial was to evaluate the safety and efficacy of a patent foramen ovale (PFO) occlator developed by Lifetech Technology (Shenzhen) Co., LTD for the treatment of cryptogenic stroke complicated with patent foramen ovale. The study required the implant to follow instructions strictly.

入选标准
- •Patients aged 18-60 years;
- •Be able to understand the purpose of the experiment, voluntarily participate in the experiment and sign the informed consent;
- •Patent foramen ovale was confirmed by chest ultrasound (TTE) or esophageal ultrasound (TEE);
- •The presence of a large right-to-left shunt was confirmed by right aspiration angiography (cTTE or cTCD);
- •It meets the clinical status of patent foramen ovale plugging indication, and at least one of the following conditions exists:
- •Cryptogenic stroke complicated with patent foramen ovale, combined with one or more clinical risk factors;
- •Cryptogenic stroke complicated with patent foramen ovale, combined with one or more anatomical risk factors of patent foramen ovale;
- •Cryptogenic stroke complicated with patent foramen ovale, with clear deep vein thrombosis or pulmonary embolism, and not suitable for anticoagulant therapy;
- •Cryptogenic stroke complicated with patent foramen ovale, but still recurred with antiplatelet or anticoagulant therapy.
排除标准
- •Carotid atherosclerotic stenosis was determined by the investigator based on CT or vascular ultrasound (> 50%);
- •Large cerebral infarction occurred within 4 weeks (MR/CT or DWI image ASPECTS score <6 points or infarction volume ≥70 ml or infarction area > 1/3 middle cerebral artery blood supply area);
- •intracardiac thrombosis or tumor, intracardiac neoplasm;
- •acute myocardial infarction or unstable angina within 6 months;
- •Left ventricular aneurysm formation or left ventricular wall movement disorder;
- •Mitral/aortic disease: including mitral stenosis or severe mitral regurgitation of any cause, severe aortic stenosis or severe aortic regurgitation, mitral or aortic valve vegetations or prior valve replacement surgery;
- •Dilated cardiomyopathy, LVEF < 35%, or other severe heart failure;
- •Patients with right-to-left shunt due to other causes, including atrial septal defect or perforated diaphragm;
- •Atrial fibrillation/atrial flutter (chronic or intermittent);
- •pregnant or planning to become pregnant during the trial;
- •Patients with active endocarditis or other untreated infections or other hemorrhagic diseases;
- •Pulmonary hypertension or patent foramen ovale was a special channel;
- •liver and kidney function impairment (ALT or AST > 3 times the upper limit of normal value, serum creatinine (Cr) > 2 times the upper limit of normal value);
- •Uncontrolled hypertension (> 180/100 mmHg);
- •Contraindication of antiplatelet or anticoagulant therapy, such as severe bleeding within 3 months, obvious retinopathy, history of other intracranial bleeding, and obvious intracranial diseases;
- •Coronary heart disease, hypertension, diabetes and other vascular diseases that are poorly controlled by drugs or other means;
- •The investigator determined that the patient was not suitable for implantation of PFO occluder (for example, the diameter of the base of the atrial septal tumor ≥25mm and the size of the foramen ovale ≥5mm) or the patient has contraindications for implantation of PFO occluder;
- •Thrombosis exists at the location or route of implantation;
- •Malignant neoplasms or other diseases with a life expectancy of less than 2 years;
- •Patients who could not be followed up during the trial;
- •Participate in clinical trials of other drugs or medical devices within three months.
结局指标
主要结局
Accurate success rate
时间窗: 6 month
180 days after the operation, transthoracic echocardiography (TTE) showed that the position and shape of the occluders were normal, and no horizontal atrial shunt was observed. Re-examination by chest echocardiographic contrast 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 resting state and Valsalva action.
次要结局
- Success rate of occluder implantation technology(one week after surgery)
- Success rate of complete occlusion(180 days after surgery)
- Effective plugging success rate(360 days after surgery)
- Recurrence or incidence of cryptogenic stroke during follow-up(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)(360 days, 2 years, 3 years, 4 years, 5 years after surgery)
- Success rate of occluder implantation(one week after surgery)
- Incidence of new atrial fibrillation and atrial flutter during follow-up period(360 days, 2 years, 3 years, 4 years, 5 years after surgery)
- All-cause mortality rate(360 days, 2 years, 3 years, 4 years, 5 years after surgery)
- Incidence of device defects.(360 days, 2 years, 3 years, 4 years, 5 years after surgery)
