Patients with severe valvular heart disease, aortic dissection, or cardiomyopathy;\n     2. High-risk patients with a history of anticoagulant therapy or currently receiving anticoagulant therapy (e.g., history of thrombosis or stroke);\n     3. Patients with severe underlying conditions such as cancer or severe diabetes;\n5. Clinical diagnosis: Persistent atrial fibrillation (PsAF)\n\n   * Inclusion criteria:\n\n     1. Patients aged 18 to 80 years;\n     2. Diagnosed with persistent atrial fibrillation (PsAF) via electrocardiogram (ECG) or Holter monitoring;\n     3.

History of stroke or clinical evidence of thrombus formation;\n3. Severe heart failure (NYHA III-IV class);\n4. High-risk cardiac conditions (e.g., acute myocardial infarction, coronary artery disease); In the above different types of rapid arrhythmias, the inclusion criteria primarily focus on the diagnosis and control of clinical symptoms for different types of arrhythmias, while the exclusion criteria focus on avoiding patients with severe comorbidities or those unable to tolerate surgery. Through this patient screening method, the safety of the study and the accuracy of the data are ensured, thereby enabling a better assessment of the clinical efficacy of the new EasyStars catheter.","ALL","18 Years","80 Years",{"count":20,"type":21},300,"ESTIMATED","INTERVENTIONAL",[24],"NA","The primary objective of this study was to evaluate the clinical feasibility, safety, and surgical characteristics of the EasyStars™ High Density Mapping Catheterin in patients with complex arrhythmias.",[27,28,29,30],"Ventricular Tachycardia (VT)","Atrial Tachycardia","Typical Atrial Flutter","Paroxysmal Atrial Fibrillation (PAF)","NOT_YET_RECRUITING","2025-07-28",{"date":34,"type":35},"2025-07-31","ACTUAL",{"date":37,"type":21},"2025-08-30",{"date":39,"type":21},"2027-12-31",{"name":41,"class":42},"Shanghai MicroPort EP MedTech Co., Ltd.","INDUSTRY",{"id":44,"slug":45,"hasResults":11,"nctId":46,"briefTitle":47,"officialTitle":47,"acronym":4,"eligibilityCriteria":48,"healthyVolunteers":11,"sex":16,"minAge":17,"maxAge":4,"enrollmentInfo":49,"targetDuration":4,"studyType":22,"phases":51,"briefSummary":52,"conditions":53,"keywords":4,"overallStatus":55,"whyStopped":4,"lastUpdateSubmitDate":56,"lastUpdatePostDateStruct":57,"startDateStruct":59,"completionDateStruct":61,"leadSponsor":63,"locationsCount":65},"100528182","an-exploratory-study-of-focal-pulse-ablation-system-in-the-treatment-of-atrial-arrhythmia-100528182","NCT06157437","An Exploratory Study of Focal Pulse Ablation System in the Treatment of Atrial Arrhythmia","Inclusion Criteria:\n\n* Subjects aged at least 18;\n* Subjects with at least one typical atrial flutter attack recorded by ECG or holter in the 180 days prior to enrollment, and the ECG of other hospitals could be accepted;\n* Subjects are able to understand the purpose of the study, voluntarily participate in the study and sign the informed consent, and are willing to complete the follow-up according to the requirements of the program.\n\nExclusion Criteria:\n\n* Any prior cavo-tricuspid isthmus ablation;\n* Unstable angina;\n* Atrial flutter secondary to electrolyte disorder, thyroid disease or other reversible causes;\n* Myocardial infarction or coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) within the prior three months;\n* At baseline, New York College of Cardiology (NYHA) heart function grades III and IV;\n* Implantable devices such as ICDs, CRTS and pacemakers in the body;\n* Atrial or ventricular tumors, blood clots, thrombus, or known clotting disorders were recorded within the prior 90 days;\n* Severe structural heart disease, including tricuspid stenosis, tricuspid malformation, or other congenital heart disease that prevents ablation surgery;\n* Previously received tricuspid metal valve replacement;\n* Thromboembolic events (including transient ischemic attacks) within the past 6 months;\n* Mural thrombosis, tumor, or other abnormality that interferes with vascular puncture or catheter operation;\n* Severe lung disease, pulmonary hypertension or any lung disease involving abnormal blood gas or severe breathing difficulties;\n* Anticoagulation contraindications and a history of blood clotting or abnormal bleeding;\n* Acute systemic infection;\n* Serum creatinine greater than twice the upper limit of normal, or any history of renal dialysis;\n* Women who are pregnant or breastfeeding or who cannot use contraception during the study period;\n* Enrollment in another clinical trial evaluating other devices or drugs during the same period;\n* Life expectancy less than 12 months (e.g. advanced malignancy);\n* Abnormalities or diseases considered by the investigator to be excluded from inclusion in this study.",{"count":50,"type":21},10,[24],"This is a prospective, single-group clinical study.
